Safety-related Digital Output Terminals
Digital outputs are connected to these terminals.
Safety-related Analog Input Terminals
The GuardPLC 1800 controller features 8 single-ended analog inputs.
Differential analog inputs cannot be used on the GuardPLC 1800
controller. Two- or four-wire transmitters can be used. These devices
can be powered from the transmitter supply terminal of the GuardPLC
1800 controller or from an external power supply. See Appendix
C for
example wiring diagrams.
