Product Overview

The Honeywell CC-GDOL11 is a high-density, intrinsically safe Digital Output IOTA (Input Output Termination Assembly) designed for the Experion PKS C300 and Safety Manager architectures. This module provides 32 independent channels for controlling discrete field devices located in hazardous areas. It acts as the physical and electrical interface between the controller and field-side apparatus such as solenoids, beacons, and sounders.

Engineered with a 12-slot redundant-capable architecture, the CC-GDOL11 ensures maximum process uptime by allowing for fault-tolerant configurations. It is specifically optimized to work in conjunction with MTL 4521 isolators, creating a secure energy-limiting barrier that prevents electrical ignition in flammable or explosive atmospheres.

Industrial Applications

The CC-GDOL11 is a critical component for distributed control systems operating in proximity to volatile substances:

• Petrochemical & Refining: Driving solenoid-actuated valves (SOV) and emergency notification devices in Zone 1 and Zone 2 hazardous areas.

• Offshore Platforms: Managing fire and gas (F&G) output signals where space-saving high-density I/O and intrinsic safety are required.

• Chemical Processing: Controlling simple apparatus and alarm indicators in batch reactor zones with high explosive potential.

• Fuel Storage Facilities: Operating remote shut-off solenoids while maintaining strict energy-limiting protection against sparks.
