Control units

Our control units evaluate the output signals of our safety mats, safety edges and safety bumpers, then they immediately trigger the necessary safety measure.

Functional monitoring by our control units applies various principles.

A monitoring resistor integrated in the sensor measures a constant closed-circuit current in safe condition. When the sensor is actuated, the voltage drops. The control unit's safety contacts open and ensure the drive is safely switched off for 1k2, 8k2 or 22k1 final resistances.
In the case of the four-wire solution, functional monitoring takes place by feeding the signals back to the control unit.

Whichever principle is applied, the control unit stops the drive on actuation or cable interruption.
