857-811 WAGO Signal Relays

Wago 857-811 is an analog transducer designed for temperature signal conditioning. 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 easy installation and utilizes a DIP switch for interface configuration, which can also be done via software or an app. 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 857-811 is protected to an IP20 degree and has a rated insulation voltage of 6 mm. Its dimensions are H94mm x W6mm x D97.8mm, and it is designed for mounting on a DIN-35 rail. The transducer includes 1 x analog input for Thermocouples types J and K, and offers 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. It features a tripping curve of 40mA at 24Vdc with a time delay at nominal load and operates within an accuracy class of 5-95% relative humidity, with no condensation permissible.
