The Real-World Problem It Solves
Bundled loose splice wiring between Tricon AI modules and field voltage transmitters creates floating reference noise. Unmarked ad-hoc splices drag out annual SIS loop proof testing by multiple shifts.
Where you’ll typically find it:
- Refinery CDU/Heater SIS cabinets for furnace thermocouple amplifier 0-10V voltage signal termination
- Thermal power plant boiler BMS racks for drum level, steam pressure analog sensor wiring
- Onshore gas plant compressor ESD shelter analog input termination enclosures
Standardized pre-labeled terminal layout eliminates makeshift field splices and speeds point-to-point loop continuity testing.
Hardware Architecture & Under-the-Hood Logic
Passive PCB design with no onboard MCU or signal conditioning circuitry; rear ribbon header mates directly to Tricon analog input module harness, isolates rack-side TMR circuitry from field-side noisy instrument wiring.
- Field voltage sensor positive (+) lands on numbered input terminal; negative (-) connects to board’s shared RTN common bus rail.
- PCB internal fixed copper traces map each numbered channel straight to corresponding rear ribbon header pinout.
- Ribbon cable transfers conditioned raw analog voltage into Tricon TMR triple-redundant input module.
- For 32-point full module coverage, stack two separate 9753-110 boards, apply included 1~16 /17~32 channel identification labels.
- Onboard isolation barrier blocks field-side transient surge from feeding back into expensive rack-mounted core AI modules.

Field Service Pitfalls: What Rookies Get Wrong
Cross-Tying RTN Common Bus to Cabinet Protective EarthNew tech jumps board RTN terminal directly to cabinet chassis ground. Ground loop current generates mV-level offset drift, causing unstable fluctuating PV readings across all 16 channels.
- Quick Fix: Leave board RTN floating per factory spec; only tie RTN to sensor negative at transmitter field end.
Mismatched Pairing When Replacing 32CH AI Module TerminationTechnician swaps only one of two paired 9753-110 boards for a 32-point input module, mismatching channel label numbering between old/new terminals. Loop checkout ends up with misassigned tag numbers during SIS proof test.
- Field Rule: Replace both paired termination boards together; re-stick factory channel labels 1-16 /17-32 post-install.
Crimping Multi-Conductor Bulk Cable Into Single Terminal SlotsField maintenance stuff 2+ separate instrument wires into one screw terminal slot. Thermal expansion inside cabinet loosens crimp, creating high-resistance intermittent open loops.
- Quick Fix: One conductor per terminal only; run multi-pair bulk cable to intermediate junction strip before landing individual leads on 9753-110.
