Article 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. 
