Safety-related Digital Inputs
The controller has 20 digital inputs whose status is indicated via status indicators when the
controller is in RUN mode.
LS+ is a voltage source that provides 24V DC for a group of four dry contact inputs. There are
five groups on the GuardPLC 1600 controller.
If devices require 24V DC to operate and use the same power source as the controller, then wire
the outputs of the device directly to inputs on the controller.
