The WAGO 857 series temperature signal conditioner features a DIP switch and software/app interface configuration, supporting one analog input for various thermocouple types (J, K, E, R, N, S, T, B) and one analog output with multiple current and voltage options (0-10mA, 2-10mA, 0-20mA, 4-20mA, 0-5Vdc, 1-5Vdc, 0-10Vdc, 2-10Vdc). It operates on a supply voltage of 16.8-26.4Vdc (24Vdc nominal) and includes Push-in CAGE CLAMP spring connections for easy installation on a DIN-35 rail (6mm width). The device is rated for ambient temperatures ranging from -25°C to +70°C and has an IP20 protection rating, equivalent to model 857811.
