Description
Honeywell CC-TDOR01 – Relay Digital Output Module for safe on/off control in Experion Series C/C300 systems
The Honeywell CC-TDOR01 is a relay digital output module used in Experion PKS Series C/C300 I/O. From my experience, it’s the go-to choice when you need electrically isolated, dry-contact control of downstream devices—solenoid valves, contactor coils, beacons, or interposing relays—without tying your control electronics directly to field power. You might notice that it slots into standard Series C I/O bases with the usual Termination Assembly (TA), making replacement and expansion straightforward for maintenance teams.

Key Features
- Relay contact outputs – Dry contacts provide galvanic isolation from the controller side, ideal for mixed-voltage plants.
- Designed for industrial loads – Typically used to switch 24 VDC or AC mains via interposing relays; helps protect upstream electronics.
- Series C/C300 ecosystem compatibility – Fits standard Honeywell Series C I/O carriers and works with the appropriate TA.
- Channel isolation – Relay channels are inherently isolated, which generally reduces cross-channel interference in noisy panels.
- Diagnostics integration – Status and health reporting appear in Experion PKS, assisting maintenance teams during commissioning.
- Field wiring simplicity – Field wiring lands on the Termination Assembly, so module swaps don’t disturb terminal screws in most cases.
Technical Specifications
| Brand / Model | Honeywell CC-TDOR01 |
| HS Code | 8537.10 (Programmable control equipment and related I/O, not exceeding 1000 V) |
| Power Requirements | Backplane powered via Series C carrier; typical module consumption is low (controller provides 5 VDC rail). |
| Operating Temperature | 0 to 55°C typical; non‑condensing environment recommended. |
| Signal I/O Type | Relay digital outputs (dry contacts); channel count and contact form depend on the matched TA configuration. |
| Communication Interface | Honeywell Series C backplane to C300 controller; no external serial/fieldbus port on the module itself. |
| Installation Method | Plugs into Series C I/O base with dedicated Termination Assembly (TA); field wiring terminates on TA; cabinet or DIN-rail mount via TA. |
| Dimensions & Weight | Standard Series C I/O module form factor; compact, panel-friendly footprint. |
Application Fields
The CC-TDOR01 is typically selected where electrical isolation and clean on/off control matter:
- Oil & gas skids: switching solenoids, small motor starters via interposing relays.
- Chemicals & pharmaceuticals: dosing pump enable, alarm beacons, valve actuation.
- Power & utilities: breaker coil command (through interposing), status lamps, trip relays.
- Water & wastewater: blower/valve control, dampers, panel indicators.
- Metals & F&B: conveyor starts, diverter gates, pilot lights, audible alarms.
One thing I appreciate is how it simplifies mixed-voltage cabinets—relay contacts let you keep the controller side SELV/PELV while handling higher field voltages on the other side.
Advantages & Value for Procurement
- Lifecycle continuity – Fits the Honeywell Experion Series C installed base, reducing engineering changes during replacement or expansion.
- Reliability in harsh panels – Relay isolation typically tolerates noisy environments better than pure semiconductor outputs.
- Lower integration risk – Native diagnostics and uniform mechanics cut commissioning time and wiring mistakes.
- Flexible load interfacing – Works with common industrial voltages and interposing relays to scale up switching capacity when needed.
- Service & spares strategy – Standard Honeywell form factor means simpler stocking and faster swap in many cases.
Installation & Maintenance
- Panel environment – Keep within 0–55°C, non‑condensing; provide ventilation and avoid heat sources directly under the module.
- Wiring – Land all field wires on the TA. Use ferrules for stranded conductors and keep power and signal wiring segregated to reduce noise.
- Load handling – For inductive loads (solenoids, contactors), add proper suppression (diodes, RC snubbers, or MOVs) to prolong relay life.
- Protection – In most cases, per‑channel fusing or appropriately sized breakers on field circuits is recommended.
- Maintenance – Periodically verify output operation in Experion, check terminal tightness on the TA, and inspect for contact wear on frequently cycled channels.
- Firmware/config – Keep the controller and I/O firmware at Honeywell‑recommended revisions; review system diagnostics after changes.
- Safety – De‑energize affected circuits before replacing modules; follow lockout/tagout and site electrical standards.
A maintenance supervisor told us they prefer the relay DO in mixed‑voltage racks because nuisance coupling is rare, and channel isolation helps during troubleshooting.
Quality & Certifications
- Manufacturing quality aligned with ISO 9001 processes.
- CE compliant; UL recognition typical for Series C modules.
- RoHS compliance in most deployments.
- Manufacturer’s warranty support available through authorized channels.
If you’re standardizing on Experion C300 and need clean, isolated on/off control, the Honeywell CC-TDOR01 seems to be the dependable relay DO module most teams expect—easy to drop in, easy to service, and forgiving with real‑world loads when properly protected.
