Safety Relays

With the safety relays of the SR series, Zander offers a series for the protection of humans as well as machines. They monitor the function of the connected safety sensors along with the wiring and function as power amplifiers for shutting down the connected power contactors or drives in a safe manner.

All the safety relays of the SR series fulfill the requirements defined by the applicable standards, right from emergency stop and safety door monitoring to 2-hand applications to furnaces in continuous operations and are tested and certified by independent testing institutes such as TÜV-Rheinland, Underwriters Laboratories or DNV GL, RINA as well as CCC.

No matter in which industry they are needed: We have the right safety relays, safety controller, safety time relays, safe coupling relays and extension modules.
