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. ## Your advantages Time saving push-in connection, tools not required - Potentials can be easily looped through – ideal for BUS applications - Intuitive use through colour coded actuation lever - Can be combined with the MSTB 2,5 range Quick and convenient testing using integrated test option ## Key Commercial Data Packing unit 1 pc GTIN ~~eo_~~ GTIN 4055626428895 Weight per Piece (excluding packing) 170.910 g ~~a [~~ Custom tariff number ~~[OOOO]~~ 85371098 Country of origin Germany ~~LO~~ ~~**OOOO**~~ ## Technical data ## Note Utilization restriction EMC: class A product, see manufacturer's declaration in the download area 02/27/2020 Page 1 / 7 https://www.phoenixcontact.com/gb/products/2702925 ## Extension module - PSR-SPP-42-230UC/URM4/4NO/2NC - 2702925 ## Technical data ## Dimensions ||Width|22.5 mm| |---|---|---| ||Height|112 mm| ||Depth|114.5 mm| |Ambient conditions||| ||Ambient temperature (operation)|-20 °C ... 55 °C (observe derating)| ||Ambient temperature (storage/transport)|-40 °C ... 85 °C| ||Max. permissible relative humidity (operation)|75 % (on average, 85% infrequently, non-condensing)| ||Max. permissible humidity (storage/transport)|75 % (on average, 85% infrequently, non-condensing)| ||Maximum altitude|≤ 2000 m (Above sea level)| |Input data||| |Rated control circuit supply voltage US
