Description

CC-HCN911: Product Overview
The CC-HCN911 is a HART communication adapter designed for integration into Honeywell’s ControlEdge™ C300 distributed control system (DCS) and safety instrumented systems (SIS). It serves as a dedicated interface for HART-enabled field devices, translating between the controller’s digital signals and HART’s hybrid analog-digital protocol (4-20mA with superimposed digital data). Its primary role is to extract process variables (e.g., pressure, temperature) and device diagnostics (e.g., sensor calibration, loop resistance) from smart transmitters, valve positioners, and other HART instruments, then transmit this data to C300 controllers for monitoring, control, and predictive maintenance.
Functionally, the adapter supports HART 7 protocol in primary/secondary master mode, enabling read/write access to device parameters and real-time diagnostic streaming. It processes 4-20mA signals with 16-bit resolution, isolating each channel to prevent ground loops and electromagnetic interference (EMI)—critical in electrically noisy industrial environments. As part of the ControlEdge C300 family, the CC-HCN911 integrates with the platform’s high-speed I/O link, hot-swappable architecture, and unified engineering tools (ControlEdge Builder), simplifying configuration and reducing integration time. This design aligns with applications requiring compliance to IEC 61508 (SIL 2) and adherence to HART Communication Foundation standards, making it suitable for continuous process industries where device health monitoring is as vital as process control.

Core Features & Customer Value​
HART 7 Support for Advanced Device Diagnostics: The CC-HCN911’s native HART 7 compatibility enables access to rich diagnostic data from smart devices, including sensor calibration dates, valve stem position, and loop health metrics. For engineers, this shifts maintenance from reactive (post-failure) to predictive—e.g., identifying a drifting pH sensor in a chemical reactor before it causes batch spoilage. The adapter’s ability to write configuration parameters (e.g., setpoint adjustment) via HART simplifies device commissioning, reducing field technician time by 20%.
Galvanic Isolation Ensures Signal Integrity: With 2500VAC isolation between channels and the C300 bus, the module prevents EMI from industrial equipment (e.g., variable frequency drives, motors) from corrupting 4-20mA/HART signals. In a refinery’s crude distillation unit, this ensures accurate pressure readings from HART transmitters mounted near high-power pumps, avoiding false control actions that could destabilize the column.
Hot-Swappable Design Minimizes Downtime: The adapter can be replaced while the system remains powered, critical for continuous processes like oil refining or power generation. Technicians simply remove the faulty unit and insert a new one; the C300 controller automatically re-establishes HART communication via I/O link. This eliminates scheduled shutdowns for module replacement, saving thousands in lost production per incident.
Seamless Integration with ControlEdge Ecosystem: As a native C300 I/O component, the CC-HCN911 is configured via ControlEdge Builder, which auto-detects HART device profiles (DD files) for plug-and-play setup. This reduces engineering time by 30% compared to third-party gateways. For a water treatment plant upgrading its DCS, reuse of existing HART sensors with the CC-HCN911 avoids costly hardware replacements.
SIL 2 Certification for Safety-Critical Applications: When integrated into a Honeywell Safety Manager SIS, the CC-HCN911 meets SIL 2 requirements (IEC 61508), enabling its use in safety functions like remote pressure interlock monitoring. Its fault-tolerant design (hardware fault tolerance ≥1) ensures reliable diagnostic data transmission for safety audits, aligning with API 556 and ISO 10418 standards.
Typical Applications​
The CC-HCN911 is deployed in systems requiring HART device integration with ControlEdge C300 controllers. In a petroleum refinery’s catalytic reformer, it connects 4 HART pressure transmitters monitoring reactor stages. The adapter extracts real-time pressure data and diagnostic alerts (e.g., “sensor drift detected”), enabling operators to adjust catalyst feed rates proactively—improving octane yield by 2%.
At a chemical plant’s polymerization reactor, the CC-HCN911 interfaces with 2 HART temperature transmitters (RTD-based) and 2 HART valve positioners. Its 2500VAC isolation prevents EMI from agitators from disrupting signals, while HART diagnostics flag a sticky valve stem before it causes reactant imbalance. Hot-swap capability allows maintenance during planned turnarounds without halting production.
In a municipal wastewater treatment plant, the module links the C300 controller to 4 HART pH sensors across aeration basins. The adapter’s -40°C cold-start capability supports outdoor installations, and HART data helps optimize chemical dosing—reducing reagent costs by 15% while maintaining EPA compliance.
