Product Description:DS3800HLOC
It has a standard-sized PCB form factor designed to fit into the
appropriate slots or racks within the control system's enclosure.
The board is populated with various electronic components such as
integrated circuits, resistors, capacitors, and transistors. These
components are carefully arranged and soldered onto the board's
surface to form the necessary circuitry for its intended functions.
It features a backplane connector on one edge that allows it to
interface with other boards and components within the Mark IV
system. This connection enables the transfer of electrical signals,
power, and data between different parts of the overall control
setup.
The primary function of the DS3800HLOC is to handle logic output
operations. It takes in digital logic signals from the central
processing or control logic of the Mark IV system. These input
signals are processed based on the pre-programmed logic on the
board itself.
Once the signals are processed, it generates corresponding output
signals that are then used to drive external devices or components.
For example, it might send signals to control actuators like fuel
valves in a turbine, solenoids in a pneumatic system, or relays
that in turn control larger electrical loads. This way, it serves
as an important intermediary between the intelligent control
algorithms running in the system and the physical components that
need to be manipulated to achieve proper operation of the turbine
or other industrial equipment.
It is designed to operate within specific environmental conditions
typically found in industrial settings. This includes being able to
withstand a certain range of temperatures, humidity levels, and
vibration. It has built-in safeguards and electrical protection
features to prevent damage from electrical surges, electromagnetic
interference, and other common issues in industrial environments.
The board is often part of a redundant or backup system setup in
critical applications like power generation turbines, where its
reliability is crucial to ensure continuous and safe operation of
the equipment it controls. Continuous monitoring and diagnostic
features may also be incorporated to allow technicians to quickly
identify any potential failures or malfunctions of the DS3800HLOC
itself through the control system's interface.

Technical Parameters:DS3800HLOC
- Input Voltage: It typically operates within a specific range of DC (direct
current) voltages. For example, it might accept an input voltage in
the range of around 5V ± a certain tolerance (say, ±0.5V), which is
provided by the power supply within the Mark IV Speedtronic system
to power its internal components and circuits.
- Output Voltage: When sending out signals to drive external devices, the output
voltage levels can vary depending on the load and the specific
output channels. Generally, it can output logic high and logic low
voltages that are compatible with standard TTL
(Transistor-Transistor Logic) or CMOS (Complementary
Metal-Oxide-Semiconductor) logic levels. For TTL, a logic high
might be around 2.4V to 5V, and a logic low could be around 0V to
0.4V.
- Signal Frequency: It is capable of handling digital signals with frequencies in the
range of several kilohertz (kHz) to tens of kilohertz. This allows
it to process the rapidly changing logic signals coming from the
control system's central processing unit and translate them into
appropriate output signals in a timely manner.
- Signal Delay: There is a certain amount of signal propagation delay from the
time an input signal is received until the corresponding output
signal is generated. This delay is typically in the nanoseconds to
microseconds range, depending on the complexity of the internal
circuitry and the specific signal path, to ensure that the overall
control system's response time remains within acceptable limits for
industrial applications.
- Output Current Capacity: Each output channel on the DS3800HLOC has a defined maximum
current-carrying capacity. For instance, it might be able to supply
up to 20mA (milliamperes) of current per output pin. This
determines the types of external loads it can drive directly. For
heavier loads like larger relays or solenoids, additional driver
circuits or relays might be needed in conjunction with the board's
outputs.
- Impedance Matching: The board's output circuitry is designed to have appropriate
impedance characteristics to match with the input impedance of the
external devices it interfaces with. This helps in maximizing
signal transfer efficiency and minimizing signal reflections that
could lead to signal distortion or incorrect operation.
- Operating Temperature: It can operate within a temperature range typically from around
-20°C to +60°C (-4°F to +140°F). This wide temperature range allows
it to function properly in various industrial environments, whether
it's in a relatively cool power plant control room or in a warmer
area near industrial machinery.
- Humidity Tolerance: It is designed to withstand relative humidity levels ranging from
about 10% to 90% (non-condensing). This protects the board from
moisture-related issues such as corrosion of components or short
circuits caused by condensation.
- Vibration Resistance: The DS3800HLOC has a certain level of resistance to mechanical
vibration. It can endure vibrations with amplitudes and frequencies
typically encountered in industrial settings, such as those from
nearby rotating machinery or during transportation of equipment,
without components becoming loose or the board suffering from
electrical malfunctions.
- Communication Protocol: It adheres to the specific communication protocols defined within
the Mark IV Speedtronic system for exchanging data and signals with
other boards and components. This might involve parallel or serial
data transfer methods, depending on the specific requirements of
the system's internal architecture.
- Data Transfer Rate: When communicating with other parts of the system, it can support
data transfer rates that are sufficient to keep up with the overall
control and monitoring requirements of the turbine or industrial
process it is involved in. For example, it might have a data
transfer rate in the range of several megabits per second (Mbps)
for certain critical data exchanges.
Applications:DS3800HLOC
- Gas Turbine Control: In gas turbine power plants, the DS3800HLOC is crucial for
precisely controlling multiple aspects of the turbine's operation.
It takes the logic signals from the control system and converts
them into outputs to manage functions like fuel injection systems.
For example, it can control the opening and closing of fuel valves
to regulate the amount of fuel supplied to the combustion chamber,
ensuring the turbine operates at the desired power output and
efficiency levels. It also helps in coordinating the operation of
air intake systems, such as adjusting the position of inlet guide
vanes to optimize the air-fuel mixture for combustion.
Additionally, it plays a role in monitoring and responding to
various parameters like temperature and pressure sensors within the
turbine, enabling safety and protection mechanisms to prevent
overheating or other critical failures.
- Steam Turbine Control: In steam turbine applications, it can be used to control steam
admission valves. By receiving signals from the overall control
system, it determines when and how much steam should be allowed
into the turbine to drive the rotor at the correct speed and
generate the required electrical power. It also participates in the
control of condenser systems and other auxiliary components related
to the steam cycle, ensuring smooth and efficient operation of the
steam turbine unit.
- Process Control in Refineries: In oil refineries, where complex processes are constantly
running, the DS3800HLOC is involved in controlling pumps, valves,
and heaters. For instance, it can control the flow of crude oil or
refined products through pipelines by operating the appropriate
valves. It might also regulate the temperature of heating elements
in distillation columns or reactors by sending signals to heating
control systems, helping to maintain the precise conditions
required for different chemical processes.
- Automated Production Lines: In manufacturing facilities like automotive plants or electronics
factories, it can be used to control robotic arms, conveyor belts,
and other automated equipment. For example, it can send signals to
robotic arms to perform specific assembly tasks, such as picking up
components and placing them in the correct positions on a product.
It can also control the speed and direction of conveyor belts to
ensure the smooth flow of materials along the production line,
improving overall production efficiency and product quality.
- Wind Turbine Control (in Hybrid Systems): In some hybrid power generation setups that combine wind energy
with other sources like gas turbines, the DS3800HLOC can be part of
the control system that manages the interaction between different
energy sources. It can help in adjusting the operation of the gas
turbine based on the availability and output of the wind turbine.
For example, when wind power generation is low, it can signal the
gas turbine to increase its output to meet the overall power demand
of the grid or the local facility. It can also be involved in
coordinating the connection and disconnection of the wind turbine
from the grid to ensure stable power supply and protect the
electrical equipment.
- Engine Test Beds: In aerospace, during the ground testing of aircraft engines (both
jet engines and turboprop engines), the DS3800HLOC can be used in
the test bed control systems. It helps in simulating various flight
conditions by controlling engine parameters like fuel flow, thrust
settings, and exhaust nozzle positions. This allows engineers to
thoroughly evaluate the performance and reliability of the engines
before they are installed on actual aircraft, ensuring they meet
the strict safety and performance requirements of the aviation
industry.
Customization:DS3800HLOC
- Programmable Logic: The internal logic of the board can often be customized to some
extent through software programming. Engineers can configure the
specific algorithms and functions that govern how the input logic
signals are processed and translated into output signals. For
example, in a gas turbine application, depending on the specific
design and performance goals of a particular turbine model, the
logic for controlling fuel valve openings based on different
operating conditions (such as varying load demands, ambient
temperatures, etc.) can be programmed precisely. This allows for
tailoring the behavior of the DS3800HLOC to optimize the operation
of the equipment it controls.
- Communication Protocol Adjustment: In some cases, the communication protocols used by the board to
interact with other components within the Mark IV system or
external devices can be customized. This might involve modifying
the way data is sent and received, perhaps to integrate with a new
type of sensor or actuator that has a slightly different
communication standard. For instance, if a plant upgrades to a new
generation of temperature sensors with a different serial
communication format, the DS3800HLOC can potentially be adjusted to
be able to communicate effectively with them.
- Output Channel Configuration: The physical output channels of the board can be customized in
terms of their functionality and load-carrying capabilities. For
example, if a particular industrial application requires a higher
current output on certain channels to drive larger solenoids or
motors directly, additional power amplification components can be
added to those specific channels during the manufacturing or
customization process. Or, if some output channels are not needed
for a specific setup, they can be disabled or repurposed for other
functions like providing diagnostic signals or being used in a
redundant backup configuration.
- Component Selection and Upgrades: Depending on the environmental conditions and performance
requirements of the application, there may be options to customize
the selection of electronic components on the board. For instance,
in a high-temperature environment like a desert-based power plant,
components with higher temperature tolerance ratings can be chosen
to replace the standard ones. Similarly, if a user desires improved
signal processing speed or better noise immunity, upgraded
integrated circuits or capacitors with enhanced performance
characteristics can be incorporated onto the DS3800HLOC.
- Connector Types and Placement: The type of connectors used on the board can be customized to
match the existing cabling infrastructure or to interface with
specific external devices more conveniently. For example, if a
plant is retrofitting its control system and has a preference for a
particular style of industrial connectors, the DS3800HLOC can be
manufactured with those connectors instead of the standard ones.
Additionally, the placement of connectors on the board can be
adjusted to better fit within the available space in the control
cabinet or to simplify the wiring layout for easier maintenance and
installation.
- Mounting Options: The physical mounting design of the board can also be customized.
It might be modified to fit into a specific type of rack or
enclosure that is used in a particular industrial setting. This
could involve changing the size, shape, or mounting holes on the
board to ensure a proper and secure fit within the equipment
housing, making it easier for technicians to install and remove the
board as needed.
- Redundant System Design: In critical applications like power generation, where system
reliability is of utmost importance, the DS3800HLOC can be
customized to be part of a redundant or backup system
configuration. This could involve duplicating certain key functions
or having additional boards in a standby mode that can quickly take
over in case of a primary board failure. The logic for switching
between the primary and backup boards and how they communicate and
synchronize with each other can be customized to meet the specific
requirements of the application and ensure seamless operation
without interrupting the overall industrial process.
