Product description
Isolation amplifier WAGO 857-403
The 857-403 isolation amplifier from WAGO with a supply voltage of 24 V DC guaranteed by galvanic 3-way separation of the input signal (current/voltage) from the output signal (current/voltage), a safe and error-free signal transmission.

The 857-403 isolation amplifier with a test voltage of 3 kV is adjusted using a DIP switch. Error or signal sifts are compensated by means of zero and span adjustment and the cut-off frequency can be defined between 100 Hz and 5 kHz. The isolation amplifier is connected using a push-in connection and mounting on a DIN 35 DIN rail.
