1. General Introduction
The DI831 is a 16 channel 48 V d.c. digital input module for the S800 I/O. The input voltage range is 36 to 60 V d.c. and the input current is 4 mA at 48 V d.c.). Each input channel consists of current limiting components, EMC protection components, input state indication LED and optical isolation barrier. The module cyclically performs self-diagnostics. Module diagnostics include:
·Process power supply supervision (results in a module failure, if detected)
·Event queue full
·Time synchronization missing.
The input signals can be digitally filtered. The filter time can be set in the range 0 to 100 ms, this means that pulses shorter than the filter time are filtered out and pulses longer than specified get through the filter.
