What is the Wago 753-477?

This analog input module processes AC and DC voltages ranging from 0 to 10 V (rms).

The module measures the rms value of the voltage and displays it with a resolution of 1 mV.

The maximum voltage must not exceed 20 V.

The differential inputs are electrically isolated.

The fieldside and internal system are electrically isolated.

The system supply powers the module.

The input channels of the module are differential inputs.

The shield directly connects to the DIN-rail.
