Series Connection of Multiple Safety Mats
The number of mats is limited by the total
series resistance per input channel. See
section, “Safety Mat Device Checkout” and
warning, ”Safety Mat Resistance Values.”

Auxiliary Monitor Contact/Solid-State Monitor Outputs Connection
The action of the auxiliary monitor contact, terminals 51-52, inversely "follows" the action of the safety outputs. Two additional solid-state
monitor outputs (at terminals Y32 and Y35) each are capable of switching up to 100 mA at 12- 24V dc. The output at terminal Y32 follows
