Monitoring of movable guards and magnetic
safety sensors
The safety module can
monitor emergency stop
circuits, control circuits for
movable guards as well as
magnetic safety sensors.
Replace the emergency
S35
stop contacts with switch
contacts or sensor contacts.
The sensors can only be
used in 2-channel configuration.
