857-809 WAGO Signal Relays

Wago 857-809 is a transducer with an analog function, specifically designed for potentiometer signal conditioning and includes a clipping circuit. It operates on a supply voltage range of 16.8-26.4Vdc, with a nominal voltage of 24Vdc, and does not require an AC supply voltage. This part features push-in CAGE CLAMP spring connections for secure and easy wiring, and its configuration can be adjusted via software or an app using a DIP switch interface. It is designed to operate within an ambient air temperature range of -25°C to +70°C and has a storage temperature range of -40°C to +85°C. The degree of protection provided is rated at IP20, and it has a rated insulation voltage (Ui) of 6 mm. The part's dimensions are H94mm x W6mm x D97.8mm, and it is suitable for mounting on a DIN-35 rail. It offers 1 x analog input for potentiometers ranging from 10 to 100kΩ and 1 x analog output with multiple signal options including 0-10mA, 2-10mA, 0-20mA, 4-20mA, 0-5Vdc, 1-5Vdc, 0-10Vdc, and 2-10Vdc. The maximum continuous operating voltage (Uc) is designed for potentiometer use, and the part can handle a resistance of 50mA at 24Vdc nominal load. It is built to withstand 5-95% relative humidity without condensation.
