TE Connectivity SRS & SRK Safety Relays

TE Connectivity's (TE) SRS and SRK Safety Relays are single and multi-function relays that help ease the interfacing between safety devices and the machinery the devices monitor. Safety relays control the safety-related part of control systems in such a way that machine operation is allowed when safety is confirmed. The safety relays come with two types of connection technologies: screw clamp (SRS) or push-in (SRK) connection. TE SRS and SRK Safety Relays help designers achieve integrated safety functions, such as self-monitoring static outputs, control of external contactors (EDM), and selectable automatic or manual restart. The multi-function relays allow four different operating modes, offering the possibility to connect and control different types of safety devices, including safety light curtains, solid-state-output devices, dual-channel emergency stops, two-hand controls, and safety photocells.
