857-550 WAGO Signal Relays

Wago 857-550 is an analog transducer featuring a current signal conditioner with a clipping circuit. It operates on a supply voltage of 16.8-26.4Vdc, with 24Vdc as the nominal voltage, and does not specify an AC supply voltage. This part utilizes push-in CAGE CLAMP spring connections for secure and efficient connectivity. It is designed for interface configuration via software or app, facilitated by a DIP switch. The ambient air temperature suitable for operation ranges from -25°C to +70°C, while it can be stored in temperatures ranging from -40°C to +85°C. The degree of protection offered by the enclosure is rated at IP20. It has a rated insulation voltage (Ui) of 6 mm and is designed for mounting on a DIN-35 rail. The response time and dimensions are specified as H94mm x W6mm x D97.8mm. It accepts 1 x analog input (0-1A / 0-5A) and provides 1 x analog output with a range of options including -10...+10mA, -20...+20mA, 0-20mA, 4-20mA, -5...+5Vdc, -10...+5Vdc, 0-5Vdc, 1-5Vdc, 0-10Vdc, and 2-10Vdc. The maximum continuous operating voltage (Uc) is noted for the analog output, and the device can handle a maximum load current of 40mA at 24Vdc nominal. It is designed to operate within an ambient humidity range of 5-95% RH, with no condensation permissible.
