The basic relays SR2C, SR3C and SR7C are 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.
