Requirements for the safety monitoring module2-channel safety input, suitable for p-type sensors with NO function. The safety monitoring module must tolerate internal functional tests of the sensors with cyclic switch-off of the sensor outputs for max. 2 ms. The safety monitoring module does not need to have a cross-wire short monitoring function.
Series-wiring of sensors:
16 self-monitoring safety sensors can be wired in series without loss ot control category 4 to EN ISO 13849-1. The redundant output of the first sensor is wired into the input of the next sensor.
The voltage drop over a long sensor chain should be taken into account when planning cable routing. It depends on several factors which are operating voltage, cable length, ambient temperature, number of sensors series connected, and input load of the safety control monitor.

Actuators must be ordered separately.
