Emergency Stop Dual-channel Devices
This example shows wiring and controller configuration when using a
POINT Guard I/O module with an emergency stop button and gate monitoring
switch that have dual-channel contacts. When used in combination with the
programs in a safety controller, this wiring is Safety Category 4 (emergency stop
button) and Safety Category 3 (gate monitoring switch).
