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. 0,25 ms. The safety monitoring module does not need to have a cross-wire short monitoring function.
Included in delivery
