857-424 WAGO Signal Relays

Wago 857-424 is an interface unit designed with a 2-channel signal splitter functionality. It operates on a supply voltage range of 9.6-31.2Vdc, with a nominal 24Vdc, and does not require an AC supply voltage. The unit features push-in CAGE CLAMP spring connections for secure and easy wiring, and its settings can be adjusted via a DIP switch. It is designed to work within an ambient air temperature range for operation of -40°C to +70°C and has a storage temperature range of -40°C to +85°C. The 857-424 supports a control voltage categorized under IP20 and has a rated insulation voltage (Ui) of 6 mm. Its dimensions are H94mm x W6mm x D97.8mm, and it is suitable for mounting on a DIN-35 rail. The interface unit accepts 1 x analog input with various ranges (0-10mA / 2-10mA / 0-20mA / 4-20mA / 0-5Vdc / 1-5Vdc / 0-10Vdc / 2-10Vdc) and provides 2 x analog outputs (0-20mA / 4-20mA / 0-10Vdc / 2-10Vdc), ensuring versatility in signal processing. It operates with a maximum load current of 35mA at 24Vdc nominal load. The transmission error is less than or equal to 0.1%, with a temperature coefficient of less than or equal to 0.01%/K, ensuring accuracy in signal splitting. The unit is designed to operate in environments with 5-95% relative humidity, non-condensing.
