Requirements for the safety monitoring moduleThe safety monitoring module must tolerate internal functional tests of the safety outputs for 250 μs –1500 μs.
The 250 μs switch-off time of the safety sensor additionally will be extended depending on the cable length and the capacity of the cable used. Typically, a switch-off time of 500 μs is reached with a 100 m connecting cable.
Included in delivery
Actuators must be ordered separately.
