Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents. Compatibility must be verified against your system firmware version and I/O configuration before substitution.
- 8C-PDODA1 → Direct replacement within the same C300 chassis; verify firmware revision
- 8C-TDOBA1 → Functionally equivalent to 8C-PDODA1 in most configurations; check terminal block compatibility
- 8C-TDODB1 → Extended-temperature or alternate certification variant; confirm application requirements
- Honeywell 8C-PAONA1 → Analog Output alternative if discrete output is not required
- Honeywell CC-TDOB01 → C300 Series DO module cross-reference (verify chassis generation)
- Third-party DO modules → Must support Honeywell FTE protocol and match backplane pinout; not recommended without Honeywell validation
Why Choose the Original Model
- Guaranteed compatibility with Honeywell Experion PKS and C300 controller firmware
- Full diagnostic support via Honeywell’s Control Builder and Station software
- Redundancy-ready architecture for high-availability process control
- Factory calibration and quality assurance traceable to Honeywell manufacturing standards
- Long-term support with Honeywell lifecycle management and spare parts availability
Typical Applications
- Oil & gas process control (valve actuation, pump control)
- Chemical and petrochemical plant automation
- Power generation and utilities
- Pharmaceutical batch control systems
- Pulp and paper manufacturing
- Water and wastewater treatment facilities
System Compatibility
- Controller: Honeywell C300 Process Controller
- DCS Platform: Honeywell Experion PKS (R400 and above recommended)
- Network: FTE (Fault Tolerant Ethernet) backbone
- Engineering Tool: Honeywell Control Builder
- Chassis: C300 I/O Link chassis (verify slot count and power budget)
Selection Guide
Use the table below to select the correct model for your application:
- 8C-PDODA1 — Standard digital output, 24 VDC, 8-channel; general process control
- 8C-TDOBA1 — Terminal block variant A; use when field wiring uses specific terminal block type
- 8C-TDODB1 — Terminal block variant B; alternate wiring configuration or extended certification
Key selection criteria: output voltage range, channel count, terminal block type, operating temperature, and required certifications (SIL, FM, ATEX). Contact Konmask.com for application-specific guidance.

Replacement & Compatibility FAQ
Q: Can 8C-TDOBA1 replace 8C-PDODA1 directly?
A: In most C300 configurations, yes — but verify terminal block type and firmware version before swapping.
Q: Is 8C-TDODB1 compatible with older Experion PKS versions?
A: Compatibility depends on the PKS release. R400 and above generally support all three variants. Confirm with Honeywell release notes.
Q: Do you supply new or refurbished units?
A: Konmask.com supplies both new and tested-refurbished units. Condition is clearly stated on each listing. Contact us for specifics.
Q: Can I use a third-party DO module as a replacement?
A: Third-party modules are not officially supported by Honeywell and may cause diagnostic or communication issues. We recommend original Honeywell modules for critical applications.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Contact us for current availability.
