SR7D - 7NO/6NC - safe coupling relay



The basic relays SR7D is a universally applicable safety relays, with which the moving parts of a machine or plant can be brought to a standstill in a hazard situation, quickly and safely.

Safety relays are applied in single- or dual-channel emergency stop circuits and in guard monitoring devices in machines and plants.
