Product description
Isolation amplifier WAGO 857-409
The 857-409 isolation amplifier from WAGO, with a supply voltage of 24 V DC, ensures safe and error-free signal transmission by safe 3-way isolation of the input signal (current/voltage) from the output signal (current/voltage).

The 857-409 isolation amplifier with a test voltage of 2.5 kV is set via a DIP switch. Errors or signal shifts are compensated by means of zero and span adjustment and the maximum operating frequency can be selected between 100 Hz and 5 kHz. The isolation amplifier is connected via push-in connections and is mounted on 35 mm DIN-rail.
