One of the most important elements of Schabus products is the relay. Whether as a potential-free contact in the exhaust air controls, for switching off the washing machine during an aquastop or as an alarm message from the gas detectors, every switching operation is handled by a relay.

A relay is simply a switch that is not operated by hand, but by electronics. The biggest advantage of a relay is that large powers can be switched with very low currents from the electronics.
