What is the Wago 750-425?

This digital input module receives control signals from NAMUR proximity sensors (per DIN EN 60947-5-6) from the field side.

Each channel of the sensors is supplied with a short-circuit-protected voltage of 8.2 V. A short circuit or a line break is indicated in the process image (1 bit) and via the red LED.

The green LED indicates the input status:

Signal current (0): LED off

Signal current (1): LED on

Field and system levels are electrically isolated.
