Application Platform: Modicon Quantum Automation Platform
technical parameter
Input points: 32 points
Channel grouping: divided into 4 groups
Input voltage: 24V DC, input voltage range is 19.2V to 30V
Logic input: positive logic (current filled type)
Voltage state: High level state 1 ensures a voltage range of 15V to 30V DC; Low level state 0 ensures a voltage range of -3V to 5V DC
Current state: In state 1, when the power supply voltage Us=5.5V and the input voltage Uin=0V, ensure that the current is ≥ 2mA; When the state is 0, ensure that the current is ≤ 0.5mA
Input impedance: 2500 Ω
Maximum leakage current: 200mA at Us=5.5V and Uin=4V
Absolute maximum input: 30V continuous, 56V continuous 1.3ms decay pulse
Response time: ≤ 1ms from state 1 to state 0 and from state 0 to state 1
Isolation feature: The isolation between the group and the bus is 1780Vrms for 1 minute; Inter group isolation is 500Vrms for 1 minute
Power consumption: 1.7W+(0.36 x number of conductive points)
Bus current requirement: 330mA
Indicator lights: 32 green LEDs for displaying input status, 1 red LED for indicating external faults, and 1 green LED for displaying bus communication status

Application scenarios
Industrial automation production line: used to detect various switch signals, sensor signals, etc. on the production line, such as checking whether the product is in place and whether the equipment is running normally, providing input signals for the automation control system, realizing the automation operation and monitoring of the production line.
Process control system: In the process control of industries such as chemical, petroleum, and power, various on-site equipment status signals can be collected, such as valve opening and closing status, pump operating status, etc., so that the control system can perform corresponding control and adjustment based on these signals.
Mechanical equipment control: Various sensors and switches connected to mechanical equipment monitor the operating status, position information, etc. of the equipment, achieving precise control and protection of the mechanical equipment, such as preventing equipment overload, overtravel, etc.
Building automation system: In intelligent buildings, it can be used to collect signals such as door and window switch status, lighting equipment status, air conditioning equipment status, etc., to achieve centralized monitoring and management of building equipment, improve the intelligence level and energy utilization efficiency of buildings.
