What is the Wago 750-473?

This analog input module processes standard 4–20 mA signals.

The input signal is electrically isolated and is transmitted with a resolution of 12 bits.

The 24 V field supply is derived from the module's power jumper contacts.

The shield directly connects to the DIN-rail.

This module supplies the short circuit-proof voltage for 2-wire signal conditioners.

A short circuit to power is indicated as an error/fieldbus failure and a message is sent to the supervisory control.
