857-819 WAGO Signal Relays

Wago 857-819 is an analog transducer featuring millivolt signal conditioning and a clipping circuit. It operates on a supply voltage range of 16.8-26.4Vdc, with 24Vdc as the nominal voltage, and does not require an AC supply voltage. This part is designed for push-in CAGE CLAMP spring connections and allows for DIP switch interface configuration via software or app. It is suitable for ambient air temperatures ranging from -25°C to +70°C for operation and can withstand storage temperatures from -40°C to +85°C. The 857-819 supports a control voltage (DC) and utilizes an IP20 communication protocol. It is designed for mounting on a DIN-35 rail and has a response time encapsulated in a housing measuring H94mm x W6mm x D97.8mm. The transducer accepts 1 x analog input with a range from -100mVdc to +1Vdc and provides 1 x analog output ranging from 0-10mA to 0-10Vdc, with a maximum load current of 40mA at 24Vdc nominal load. It is built to withstand mechanical resistance and operates efficiently within a humidity range of 5-95% RH, with no condensation permitted.
