Description

The Honeywell CC-GAIX11 is a Redundant Analog Input GI/IS IOTA (Galvanic Isolation / Intrinsically Safe Input Output Termination Assembly) designed for high-availability process control within the Honeywell Experion PKS Series C I/O architecture. It provides the physical and electrical interface required to land field sensor signals and route them securely to paired Series C Analog Input Modules, such as the CC-PAIH01, CC-PAIH02, CC-PAIX01, or CC-PAIX02.

Built for critical industrial operations, the CC-GAIX11 incorporates redundant IOM mounting positions directly on the board. This configuration allows two compatible Series C Analog Input Modules to operate in a parallel, redundant setup without requiring external switching hardware or additional cross-cabling. The assembly provides built-in signal conditioning and field power distribution, ensuring reliable data acquisition from 4-20mA and voltage transmitters across demanding processing environments.

Features

• Redundant Architecture: Supports two plug-in Series C I/O modules on a single assembly for seamless hardware fault tolerance.
• Galvanic Isolation / Intrinsically Safe (GI/IS) Support: Formed specifically to interface with galvanically isolated field circuits for safety-critical plant environments.
• Compact 12-Inch Form Factor: Standardized 12-inch (304 mm) IOTA footprint maximizes cabinet density while providing full termination access.
• Direct-Bus Powering: Receives primary 24 VDC operating power directly from the mounting carrier bus, eliminating extra power distribution wiring.
• Integrated Signal Routing: Combines process signal conditioning and redundant network bus connection (I/O LINK) on a single board assembly.
• Detachable Screw Terminals: Features two-level field wiring terminals to facilitate simplified installation, maintenance, and field loops testing.

Applications

• Hazardous Area Field Interfacing: Integrates process transmitters installed in demanding process zones into the Experion C300 controller platform.
• Redundant Analog Data Acquisition: Guarantees uninterrupted monitoring of critical process variables such as flow, pressure, level, and temperature.
• DCS Cabinet Optimization: Reduces overall enclosure footprint by integrating field terminations, power distribution, and redundancy on one board.

Installation Guidelines

1. Pre-Installation Inspection: Verify that the CC-GAIX11 assembly is undamaged and that the mounting carrier slots are clean and free of debris.
2. Mounting: Securely mount the IOTA onto the Series C cabinet enclosure base or carrier rail, ensuring proper engagement with the 24 VDC power bus.
3. Wiring Connections: Land field wiring on the two-level detachable terminal blocks using stranded wire up to 12 AWG (2.5 mm²). Ensure shield and signal commons are properly routed according to plant grounding guidelines.
4. Module Insertion: Carefully align and plug the designated Analog Input Modules (e.g., CC-PAIH02 or CC-PAIX02) into the primary and redundant IOM positions on the IOTA until fully seated and locked.
5. Power Verification: Confirm proper 24 VDC supply voltage at the carrier bus prior to commissioning control loops.
