2.4 Inputs and outputs
The sensor of the safety switch provides the following inputs and outputs via the 8-pos. M12
connector:
– 24 V supply connection
– 2 safety inputs
– Start/reset input
– 2 safety outputs (OSSD)
– 1 signal output/diagnostic output
2.4.1 24 V supply connection
Designation: UB, 0 V
Power supply of sensor The UB and 0 V connections are used to supply the sensor with adequate voltage. When
doing so, observe the requirements on the power supply.
See Section “Electrical safety” on page 10.
See Section “Technical data for the sensors” on page 57.
Protect the power supply with a suitable external fuse.
See Section “Fuse protection for the power supply” on page 34.
Power supply of actuator The actuator is inductively supplied with power via the sensor as soon as the actuator has
reached the switch-on distance.
2.4.2 Safety inputs
Designation: FI1A, FI1B
Safety inputs FI1A and FI1B are used for safe series connection of several safety switches.
Safe series connection Connect the safety inputs of the first switch in a series connection to 24 V DC. Connect the
safety inputs of all other switches in the series connection to the safety outputs of the previ-
ous safety switch.
Single switch When using a single safety switch, connect the safety inputs to 24 V DC.
