ABB ICSI16D1 Procontic CS31 Remote Digital Input Unit
The ABB ICSI16D1 (Product ID FPR3315101R0036) is a 16-channel binary input remote unit designed for decentralized signal acquisition within ABB Procontic CS31 control networks. It interfaces field devices such as switches, sensors, and pushbuttons directly with the CS31 system bus, reducing field wiring distances and expanding distributed control capacity.
Signal Processing and System Bus
The unit features 16 non-isolated 24 V DC digital inputs referenced to a common potential. Input debounce delay is configurable between approximately 2 ms and 32 ms to filter mechanical contact chatter and electrical noise. While the input channels share a common reference, the internal CS31 bus interface is galvanically isolated from the module's processing circuitry.
Diagnostics and Hardware Configuration
Diagnostic monitoring includes real-time status indication via 16 individual yellow LEDs alongside system-level indicators for unit errors, bus errors, and wire-break detection. The FPR3315101R0036 version operates from a 230 V AC (50/60 Hz) main power supply, providing an integrated 24 V DC auxiliary sensor supply up to 100 mA. The unit mounts on standard DIN rail or panel surfaces via ECZ module carriers.

Frequently Asked Questions
Q: What is the power supply requirement for the ICSI16D1 (FPR3315101R0036)? A: The FPR3315101R0036 variant operates on a 230 V AC (50/60 Hz) supply and includes an internal auxiliary supply delivering 24 V DC (up to 100 mA) for field sensors.
Q: Are the digital input channels galvanically isolated from each other? A: No, the 16 digital inputs are non-isolated and potential-referenced, though the CS31 system bus interface is galvanically isolated from the module circuitry.
Q: How are input signals stabilized in electrically noisy environments? A: The module provides configurable input delay filtering ranging from approximately 2 ms to 32 ms to suppress signal noise and switch contact bounce.
