753-421 - 2-channel digital input; 24 VDC; 3 ms; Diagnostics
- Brand: Wago
- Product Code: 753-421
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.
