Product Introduction
Honeywell CC- is the standard HART analog output module for Experion C300 Series-C systems. It provides 16 isolated 4–20mA outputs with native HART support, making it ideal for smart control valves, positioners, and I/P converters.
Unlike non-HART modules, this unit lets you access valve diagnostics, travel feedback, and remote calibration directly from the DCS without extra hardware.
Each channel is fully isolated to eliminate ground loops and ensure stable output in noisy industrial environments. Built-in fault detection alerts you to open wires, short circuits, and overloads before they cause process upsets.
This module is fully hot-swappable and supports redundant configurations for critical continuous-process applications.
Key Selling Points & Differentiators
- 16-channel HART native output eliminates external HART modems and reduces rack space
- 16-bit high resolution delivers precise valve control for tight PID loops
- Full galvanic isolation eliminates ground-loop noise and signal drift
- Advanced per-channel diagnostics reduce unplanned downtime
- HART 7 support provides full valve health monitoring and remote trim
- Hot-swap and redundancy ready for mission-critical processes
- Direct replacement for legacy discontinued Series-C systems
- Factory bench-tested with full calibration reports for audit compliance
Technical Risk Avoidance Guidance
1. Wrong Termination Assembly
- Risk: Using non-TAOX IOTA disables HART and isolation
- Fix: Only use CC-TAOX01 / CC-TAOX11
2. Overloaded Loop Resistance
- Risk: >650Ω causes unstable 20mA output
- Fix: Calculate total loop resistance; use boosters for long runs
3. Exceeding 30m Type 5 Cable
- Risk: Communication errors, HART dropouts
- Fix: Keep interconnect cables ≤30m
4. Unsupported Firmware
- Risk: R401+ breaks HART and redundancy
- Fix: Only use with Experion R400 or older
5. Non-Isolated Wiring
- Risk: VFD noise causes valve hunting
- Fix: Use double-shielded cable, separate from power lines
6. ESD Damage
- Fix: Always use anti-static wrist straps
FAQ
- Can CC- replace non-HART CC-PAOX01?Yes, but requires HART configuration and TAOX termination.
- What is max load resistance?650 Ω @24VDC.
- Is it compatible with C200 TC-series?No, only C300 Series-C.
- Does it support redundancy?Yes, with CC-TAOX11 IOTA.
- What HART version?HART 7.
- Is this module still supported?It is discontinued; stock is limited new surplus.
- Can I use it in SIS?No, it is DCS-only, not SIL-rated.
