Key Features & Advantages

1. 16-Channel High-Density Isolated DI Design

   Integrate 16 signal acquisition circuits on single board, reduce the quantity of modules inside control cabinet and cut spare part inventory cost. Independent isolation per channel avoids cross-talk between field signals.

2. Wide Compatibility with Field Switch Devices

   Supports both passive dry contact feedback (valve position, limit switch, safety interlock gate) and active 24VDC wet contact signals, fully matching all common discrete field sensors in power and process industries.

3. Online Hot-Swap Maintenance Function

   Support replacement without shutting down the entire DCS rack, only the single faulty channel loses signal temporarily, no impact on other equipment control loops, minimize production downtime during overhaul.

4. Full Channel Real-Time Self-Diagnosis

   Continuously detect open-circuit and abnormal input status, upload fault information to central HMI for alarm notification. Front panel LED lights enable maintenance staff to quickly locate faulty wiring or sensors on site without testing instruments.

5. Symphony Plus System Native Matching

   Plug-and-play compatible with Symphony Plus control racks, unified engineering software for configuration, no extra driver or conversion hardware required for system commissioning.
