GuardPLC 16-Digital Inputs and 8-Digital Outputs Module 9
Publication 1753-IN011A-EN-P - October 2005
Safety-Related Digital Inputs
The module has 16 digital inputs whose status is indicated via LED indicators when
the controller or module is in the RUN mode. Refer to page 4 for location of digital
inputs and LED indicators.
LS+ is a voltage source that provides 24V dc for a group of four inputs.
If devices require 24V dc to operate and use the same power source as the
GuardPLC, wire the outputs of the device directly to inputs on the GuardPLC.
