ABB 1SVR550110R1100 Safety Relay Module 24VDC

ABB 1SVR550110R1100 Safety Relay Module 24VDC is a compact safety relay designed for machine safety circuits. It provides a single changeover contact (1 c/o) controlled by a 24 V DC coil, making it suitable for interlocks, emergency-stop devices, and safety-gate monitoring. The device is part of ABB's 1SVR safety-relay family and is intended to be wired into control panels to ensure a defined safe state when protective devices are triggered. For this variant, ABB lists a time-delay function in the 0.3–30 s range, enabling a short, programmable delay before the relay output changes state. The module supports 24 V DC operation and is used to implement safety logic in a variety of applications, including conveyor lines, presses, and robotic cells, where a reliable safety stop is required. Its form factor and electrical interface are designed to be compatible with ABB's safety-relay ecosystem and standard control circuits.
