857-800 WAGO Signal Relays

Wago 857-800 is an analog transducer designed for temperature signal conditioning. It operates on a supply voltage range of 16.8-26.4Vdc, with a nominal 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 settings can be adjusted via a DIP switch. It is designed to operate within an ambient air temperature range of -25°C to +70°C and can be stored in temperatures ranging from -40°C to +85°C. The 857-800 offers a degree of protection rated at IP20 and is mounted on a DIN-35 rail. It has a response time detailed for specific configurations and dimensions of H94mm x W6mm x D97.8mm. The transducer supports 1 x analog input for RTD Pt100 / Pt200 / Pt500 / Pt1000 / Resistor with mechanical resistance options of 0-1kΩ and 0-4.5kΩ, and it can be configured for 2-wire / 3-wire / 4-wire systems. Additionally, it provides 1 x analog output capable of various signal outputs including 0-10mA, 2-10mA, 0-20mA, 4-20mA, 0-5Vdc, 1-5Vdc, 0-10Vdc, and 2-10Vdc. The maximum continuous operating voltage is specified for its nominal load, and it can handle an environment with 5-95% relative humidity, provided there is no condensation.
