857-411 WAGO Signal Relays

Wago 857-411 is a single-channel isolation amplifier designed for sensor signal amplification. 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 is designed for use within an ambient air temperature range for operation of -25°C to +70°C and for storage from -40°C to +85°C. It offers IP20 protection and is suitable for mounting on a DIN-35 rail. The 857-411 has a rated insulation voltage of 6 mm and dimensions of H94mm x W6mm x D97.8mm. It supports 1 x analog input (0-20mA / 4-20mA) and 1 x analog output (0-20mA / 4-20mA), with a maximum output of 25mA at 24Vdc 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. It is designed to operate within a humidity range of 5-95% RH, with no condensation permissible.
