The digital input signals connected to the digital input module have normally open contacts. Does this module detect Earth faults on these inputs signals


#1

The Safety system has a Earth Leakage Detector module (10310/./1) installed.
The digital input signals connected to the digital input module have normally open contacts. Does this module detect Earth faults on these inputs signals.

A short between the +24VDC and earth will be detected.
A short between the return line to the input channel will not be detected if no converter module is used:

For the input module SDI-1624, use input converter module BSDI-16UNI
SM: digital input module type SDI-1624 placed in a redundant or non redundant IO Chassis
FSC: digital input module type 10101/2/1 placed in a redundant or single IO rack
