Schmersal SRB-ZB-QS-230V Relay

Schmersal SRB-ZB-QS-230V is a safety relay module in the SRB family designed to monitor safety-related inputs and generate safe control outputs for machinery. The model, SRBZBQS230V, is configured for 230 V AC operation and is listed in distributor catalogs under the Schmersal/ELAN branding, reflecting its role as a compact, field-device safety relay. Weighing approximately 0.75 kg, this unit is described as a safety relay module intended to process safety signals from protective devices and drive appropriate safe outputs on industrial equipment. Manufacturer references indicate the SRB-ZB-QS-230V variant has been discontinued, so users should explore current SRB options from Schmersal for ongoing support and compatibility. Typical applications involve safety circuit monitoring for devices such as protective doors, interlocks, and emergency-stop configurations on automated lines, where EN 60204-1-compliant safety logic is required. The SRB series consolidates multiple safety functions into a single module to simplify wiring and oversight of safety circuits in manufacturing environments. This particular 230 V AC variant distinguishes itself from lower-voltage SRB models, making it suitable for installations where mains-supplied safety logic is standard. When integrating, verify that inputs and outputs match your existing safety devices and that wiring adheres to applicable safety standards to maintain proper machine protection.
