Process Automation Solution – Honeywell 8C-TAIX61 | 51306977-175 | C300 Series
Where This Product Is Used
The Honeywell 8C-TAIX61 (P/N 51306977-175) Digital Input Module is purpose-built for demanding industrial environments where reliable discrete signal acquisition is critical. Typical deployment sites include:
- Oil & Gas Refineries – Monitoring valve open/close status, pump run/stop signals, and emergency shutdown (ESD) feedback loops.
- Chemical & Petrochemical Plants – Capturing digital status from field instruments, motor control centers (MCC), and safety interlocks.
- Power Generation Facilities – Integrating breaker status, turbine protection signals, and generator control feedback into the DCS.
- Pulp & Paper Mills – Reading conveyor status, agitator run signals, and process interlock states.
- Pharmaceutical Manufacturing – Acquiring clean-room equipment status and batch process digital triggers under GMP-compliant control architectures.
- Water & Wastewater Treatment – Monitoring pump stations, valve actuators, and level switch states across distributed field sites.

Application-Specific FAQ
Q: Is the 8C-TAIX61 compatible with Honeywell Experion R500 and above?
A: Yes. The module is fully compatible with Experion PKS R500.x through the latest R520.x releases. Verify firmware revision alignment with your system integrator.
Q: Can this module be used in SIL 2 safety loops?
A: The 8C-TAIX61 can be incorporated into SIL-capable architectures when paired with a certified Safety Manager configuration. Consult Honeywell’s TÜV-certified SIL documentation for your specific loop design.
Q: What is the difference between 8C-TAIX61 and 8C-TAIX51?
A: The 8C-TAIX61 supports higher input voltage ranges and enhanced optical isolation compared to the TAIX51 variant. The 51306977-175 suffix denotes the specific hardware revision and regional compliance marking.
Q: Do you offer a warranty?
A: All units carry a 12-month functional warranty from date of shipment. DOA (Dead on Arrival) units are replaced at no charge within 30 days.
Q: Can I return a module if it doesn’t fit my system?
A: Yes. We accept returns within 30 days of delivery for unused, uninstalled modules in original packaging. Contact support@konmask.com to initiate an RMA.
