DC (10...30V) Input Module 15
Publication 1771-IN028D-EN-P - October 2008
Status Indicators
The module has 32 status indicators on the front plate.
These represent the control status of the input. Each indicator is lit when voltage is present at
the corresponding input.
These indicators can flicker (momentarily light up) when the chassis in which the module
resides is first powered up. This flicker is normal and in no way affects the control parameters
of the system.
