The CC-GAIX21 is a specialized high-density Input/Output Termination Assembly (IOTA) within the Honeywell Experion PKS Series C architecture, designed for analog input applications requiring Galvanic Isolation (GI) and Intrinsic Safety (IS). It provides the critical interface between field wiring and Series C analog input modules, enabling safe connection of 4–20 mA transmitters in hazardous environments.
Engineered for use in explosive atmospheres, the CC-GAIX21 integrates isolation and safety barriers directly into the IOTA, eliminating the need for external safety barriers or marshaling hardware. This significantly reduces cabinet footprint, wiring complexity, and overall system cost while maintaining high reliability.
The module supports high-speed communication with the C300 controller and ensures robust protection against electrical surges, making it ideal for demanding industrial applications where both safety and performance are critical.
| Parameter | Specification |
|---|---|
| Component Type | Analog Input I/O Termination Assembly (IOTA) |
| Signal Protection | Integrated Galvanic Isolation (GI) / Intrinsically Safe (IS) |
| Product Family | Series C I/O |
| Model Identification | CC-GAIX21 |
| Channel Capacity | 16 Channels |
| Configuration | Simplex (Non-Redundant) |
| Compatible Modules | CC-PAIX01 / Series C Analog Input Modules |
| Signal Range | 4–20 mA |
| Field Wiring | IS-rated multi-core and single-core cables |
The CC-GAIX21 is widely used in oil and gas upstream facilities, chemical storage terminals, and fuel loading systems. It is specifically designed for instrumentation located in Zone 0 and Zone 1 hazardous areas, where intrinsically safe signal conditioning is required to prevent ignition risks.
Does the CC-GAIX21 require external safety barriers?
No, the CC-GAIX21 integrates galvanic isolation and intrinsic safety circuitry, eliminating the need for external safety barriers. This reduces both installation cost and cabinet space requirements.
Can this IOTA be used for redundant I/O configurations?
No, the CC-GAIX21 is a simplex (non-redundant) termination assembly. For high-availability systems, a redundant IS-IOTA such as the CC-GAIX11 is required to support dual-module redundancy.
