857-450 WAGO Industrial Automation Components

Wago 857-450 is an amplifier designed for sensor applications, featuring a single-channel isolation amplifier with zero/span adjustment capabilities. It operates on a supply voltage range of 8-30Vdc, including nominal values of 12Vdc and 24Vdc, and is equipped with push-in CAGE CLAMP spring connections for easy installation. The design incorporates a DIP switch and is loop-powered via output. This part does not require an AC supply voltage and is designed to operate within an ambient air temperature range of -25°C to +70°C, with a storage temperature tolerance of -40°C to +85°C. The degree of protection is rated at IP20, and it supports a wide range of input signals including analog inputs from -5...+5mA up to -20...+20Vdc, and outputs a 4-20mA analog signal. The device boasts a transmission error of ≤0.1% and a temperature coefficient of ≤0.01%/K, ensuring accuracy and stability in performance. It is designed for mounting on a DIN-35 rail, with dimensions of H94mm x W6mm x D97.8mm, and can operate in environments with 5-95% relative humidity, provided there is no condensation.
