Please find the complete data in the user's documentation. 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, pluggable Push-in terminal block, width: 22.5 mm The figure shows a version with a screw connection ## 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. ## 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<br>42 V AC/DC ... 230 V AC/DC -15 % ... +10 % (Rated control circuit<br>supply voltage US)<br>Rated control supply current IS<br>typ. 35 mA (42 V DC)<br>typ. 15 mA (230 V AC)<br>Power consumption at US<br>max. 1.5 W (with DC)<br>max. 1.7 W (with AC)<br>Inrush current<br>< 38 A (Δt = 50 µs at Us)<br>Typ. starting time with Us<br>< 100 ms (when controlled via A1)<br>Typical release time<br>< 20 ms (Control via A1 at 42 V DC)<br>< 200 ms (Control via A1 at 230 V AC)<br>Recovery time<br>< 1 s<br>Operating voltage display<br>1 x green LED<br>Protective circuit<br>Surge protection Suppressor diode and varistors<br>Maximum switching frequency<br>0.5 Hz<br>~~—_~~||| |Output data||| |Contact type<br>Contact material<br>Maximum switching voltage<br>Minimum switching voltage<br>Limiting continuous current<br>Maximum inrush current<br>Inrush current, minimum<br>Sq.
