GuardPLC 16-Digital Inputs and 8-Digital Outputs Module 15
Publication 1753-IN011A-EN-P - October 2005
Pulsed Output Terminals
All PO1 and PO2 terminals are internally connected. Therefore all PO1 and PO2
terminals pulse together.
Safety-Related Digital Outputs
The module has 8 output pairs whose status is indicated via LED indicators. The
digital outputs are not electrically isolated.
An output is in the safe state when it is de-energized. If a channel faults, the
affected outputs are switched off. If the module faults or loses ethernet
communications, all outputs are switched off.
An overload at an output causes the output to turn off. If the total current is greater
then 9 A, all outputs are turned off. When the overload is eliminated, the outputs
are activated according to their current software-driven state.
