Description
This digital input module receives control signals from the field side and supplies a short-circuit proof voltage to the sensors. The module transfers the control signals and other information via a fieldbus coupler to the higher-level controller.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.
