Features

• 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
