ABB DI890 3BSC690073R1 Digital Input Module Over-VoltageProduct Details
The DI890 Digital Input Module has 8 channels. The module includes
Intrinsic Safety protection components on each channel for
connection to process equipment in hazardous areas without the need
for additional external devices. Each channel is galvanically
isolated from the power supply, ground, and each other.
Intrinsically safe Proximity sensors or volt-free contacts can be
powered and monitored by any channel.
The Proximity sensor should conform to the NAMUR standard and line
faults can be detected without any additional external components.
For line faults to be detected when using volt-free contacts,
external resistors should be connected in series and in parallel to
enable the state of the field circuit to be sensed by the input
channel. All eight channels are galvanic isolated from the
ModuleBus and power supply individually. Power to the input stages
is converted from the 24 V on the power supply connections. Three
LEDs indicate module status Fault (Red), Run (Green) and Warning
(Yellow).
TU890 and TU891 Compact MTU can be used with this module and it
enables two wire connection to the process devices without
additional terminals. TU890 for Ex applications and TU891 for non
Ex applications.
