The WAGO 857 series 2-channel signal splitter features a DIP switch and supports one analog input (0-20mA, 4-20mA, 0-5Vdc, 1-5Vdc, 0-10Vdc, 2-10Vdc) and two analog outputs (0-20mA, 4-20mA). It operates on a supply voltage of 16.8-31.2Vdc (24Vdc nominal) and utilizes Push-in CAGE CLAMP spring connections. Designed for DIN-35 rail mounting with a 6mm width, it is rated IP20 and can function in ambient temperatures ranging from -25°C to +70°C. This model is equivalent to 857423.
