SICK RLY3-OSSD200 Safety Relay

RLY3-OSSD200 Safety Relay from SICK (ReLy series, ordering number 1085344) is a 24 VDC safety relay designed to interface with OSSD-enabled sensors, providing two independent safety channels with OSSD outputs for two separate safety circuits. This DIN-rail mounted module is intended for integration with safety devices such as light curtains and guarded sensors to meet functional safety requirements in automated machinery. The device is specified for IEC 61508 SIL 3 safety integrity and supports PL e in corresponding safety architectures, delivering a robust signaling path to safety controllers. As part of the ReLy safety-relay family, the RLY3-OSSD200 emphasizes straightforward wiring and reliable fault monitoring while delivering solid-state OSSD signaling to feed safety controllers with clear, discrete safety-state information. Typical applications include stop/start enable functions on packaging lines, robotic cells, conveyors, and other automated production systems where two channels must be monitored and controlled for safe machine operation. The model is widely distributed and documented under the 1085344 product number, reinforcing its role as a two-channel safety relay designed for OSSDs and DIN-rail installation.
