857-450 Loop-Powered Isolation Amplifier Datasheet

This data sheet describes WAGO's loop-powered isolation amplifier (item 857-450), which converts, amplifies, filters, and electrically isolates standard unipolar/bipolar analog signals without requiring an additional supply voltage. It features DIP switch configuration, zero/span adjustment, calibrated measurement range switching, and 3-way electrical isolation with 2.5 kV test voltage, supporting bipolar current and voltage input signals with a current output signal.
