The CC-GDIL11 is a high-availability Input/Output Termination Assembly (IOTA) within the Honeywell Experion PKS Series C platform, designed to support redundant 32-channel digital input modules with Galvanic Isolation (GI) and Intrinsic Safety (IS) protection. It provides the essential interface between hazardous-area field devices and the C300 controller, ensuring safe and reliable acquisition of discrete signals such as switch contacts and proximity sensors.
Engineered for mission-critical applications, the CC-GDIL11 integrates intrinsic safety barriers directly into the IOTA, eliminating the need for external isolators and reducing cabinet complexity. Its dual-module architecture enables full redundancy—if one module fails, the secondary module seamlessly continues operation without interrupting signal acquisition or control logic.
The module is optimized for high-density cabinet layouts, featuring a vertical mounting design and robust backplane architecture that supports efficient wiring and stable operation in harsh industrial environments.

The CC-GDIL11 is widely used in offshore oil platforms, LNG terminals, and chemical processing plants, where reliable monitoring of digital inputs is critical. It is specifically designed for hazardous environments (Zone 0 and Zone 1), making it ideal for safety-related applications such as emergency shutdown systems, interlock monitoring, and critical alarm detection.
Does the CC-GDIL11 provide power to field sensors?
Yes, the CC-GDIL11 supplies intrinsically safe 24V DC power to field devices, ensuring that energy levels remain below ignition thresholds even under fault conditions, making it safe for use in hazardous areas.
How does redundancy work on this IOTA?
The CC-GDIL11 supports a dual-module configuration with primary and secondary slots. If the primary module fails, the secondary module automatically takes over signal processing, ensuring uninterrupted communication with the C300 controller and continuous system operation.
