Siemens LZS:PT coupling relays are complete units comprising a plug-in industrial relay, socket, LED module, fixing/ejection bracket and labeling plate. The relay has a test button. Versions with standard socket (screw) or socket with logical separation (screw or spring-loaded push-in) are available.
