- Ultra-fast response time (< 2 ms) ideal for high-speed switch status acquisition
- Channel-specific LED indicators (green = closed) for quick on-site status verification
- Built-in diagnostic functions for short-circuit and open-circuit fault detection and reporting
- Hot-swappable design enables zero-downtime maintenance
- Wide operating voltage range for resistance to voltage fluctuations
Structure and Components
- 16 optoelectronically isolated digital input channels
- LED status indicator for each individual channel
- Diagnostic circuit (short-circuit/open-circuit detection)
- Backplane power supply and communication interface
- Rack-mount DIN rail structure for secure installation in Symphony® racks
Application Areas
- Power plants: Monitoring status of steam turbines, auxiliary machinery, and circuit breakers
- Hydropower stations & substations: Interlocking of disconnectors, earthing switches, and circuit breakers
- Petrochemical plants: Status monitoring of valves, compressors, and flare systems
- Water treatment & sewage plants: Control and status tracking of pumps, bar screens, and chemical dosing pumps
- Other scenarios with ABB Symphony® systems: Rail transit and energy management systems for large-scale buildings
Installation and Maintenance
Pre-Installation Preparation
- Ensure the rack is powered off or in hot-swappable mode
- Inspect backplane connectors for cleanliness
- Use wires that meet specifications (1.5 mm² recommended) and refer to the wiring diagram for correct connections
Installation Method
- Insert the module into the Symphony® rack via DIN rail mounting; electrical connection is completed through backplane power supply
Routine Maintenance
- Conduct regular inspections of LED indicators
- Periodically check for loose wiring terminals
- Inspect field contacts for inputs with frequent signal fluctuations
Replacement and Repair
- The module supports hot-swapping; wear an anti-static wristband during operation and ensure the spare module matches the exact model
- Verify functional normalcy via upper-level software after replacement
Diagnostics and Fault Handling
- Leverage the module’s built-in short-circuit/open-circuit diagnostic capabilities to quickly locate faults, which will trigger alarms in the DCS system
