857-412 WAGO Signal Relays

Wago 857-412 is a single-channel isolation amplifier designed for sensor signal amplification. It operates with 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 is designed for use within an ambient air temperature range for operation from -25°C to +70°C and for storage from -40°C to +85°C. The 857-412 offers an IP20 degree of protection and is mounted on a DIN-35 rail. It has a response time tailored for applications requiring a 1 x analog input (0-10Vdc / 2-10Vdc) and 1 x analog output (0-10Vdc / 2-10Vdc), with a maximum current consumption of 25mA at 24Vdc under nominal load. The transmission error is less than or equal to 0.1%, and the temperature coefficient is less than or equal to 0.01%/K, ensuring minimal signal distortion. The device is designed to operate within a humidity range of 5-95% RH without condensation. Its dimensions are H94mm x W6mm x D97.8mm, making it compact for installation in various industrial settings.
