Wago 753-421 Digital input module fieldbus module

2-channel digital input, 24 V DC, 3 ms The digital input module receives control signals from digital field devices and supplies sensors with power protected against short circuits. The module transfers the control signals and other information via fieldbus coupler to a supervisory control.

Each input module has a noise-rejection filter.

Each sensor can be supplied separately. A short circuit to ground is indicated as an error/fieldbus failure and a message is sent to the supervisory control.

The error is canceled automatically after it has been rectified.

Field and system levels are electrically isolated.
