Our General Terms of Use for Downloads are valid (http://phoenixcontact.com/download) 1 or 2-channel contact extension with wide range input, 4 N/O contacts, 1 N/C contact, 1 confirmation current path, together with basic device up to Cat. 4, PL e according to EN ISO 13849, plug-in screw terminal block, width: 22.5 mm ## Product Description The URM4 contact extension device enables safety-related signals to be further processed as floating contacts for an input voltage range of 42 to 230 V AC/DC. The contact extension device specifically covers the operating range above a nominal voltage of 24 V. The new device is approved in accordance with EN 50156 and can therefore be used in furnaces without any additional effort. In particular when used in conjunction with the corresponding PSR safety relay as a basic device, safety circuits up to PL e or SIL 3 can be implemented. ## Key Commercial Data Packing unit 1 pc GTIN ~~Lit~~ GTIN 4055626429106 Weight per Piece (excluding packing) 199.000 g ~~[Do |~~ Custom tariff number 85371098 ~~[Lo~~ Country of origin Germany ~~LO~~ ## Technical data Note |Note|Note| |---|---| |Utilization restriction
