Applications
The DI828 excels in industrial environments where reliable 120V AC/DC signal monitoring is critical. Typical applications include:
- Motor control centers (MCC) for status monitoring of contactors and breakers.
- Packaging machinery for discrete sensor input collection.
- Process control systems requiring isolated input channels to prevent ground loops.
Its individually isolated channels and built-in voltage supervision make it ideal for high-EMI environments.
Installation & Setup
Mount the DI828 onto a standard S800 I/O rail using the TU851 mounting terminal unit. Ensure the module is correctly keyed to prevent misinsertion. Connect field wiring to the TU851 terminals, observing the input voltage ranges. For voltage supervision, wire channel 1 (for channels 2-8) or channel 16 (for channels 9-15) to the process voltage source. After power-up, verify the Run LED is lit and the Warning LED is off. No calibration is required.
Maintenance & Reliability
This solid-state module requires no routine maintenance. Periodically inspect the front LEDs for fault indications. Keep the module free from dust and moisture; the IP20 rating requires installation in an enclosure. The module's robust design ensures long-term reliability, reducing downtime and maintenance costs.
Compatibility & Integration
The DI828 is part of the ABB S800 I/O family and communicates over the ModuleBus. It is compatible with ABB AC 800M controllers and other S800-compatible systems. The TU851 mounting terminal unit is required for operation.
Selection Guide
Before purchasing, verify that your system supports the S800 I/O series and that the TU851 MTU is available. Ensure the input voltage matches your field signals. For expert advice and guaranteed genuine parts, choose PLC Source PRO as your trusted supplier.
