GE IC694TBB132 – Barrier‑Style 32‑Point Terminal Block for PACSystems RX3i I/O

The GE IC694TBB132 is a barrier‑style terminal block designed for PACSystems RX3i 32‑point I/O modules. From my experience, it’s the piece that quietly makes commissioning smoother—clean screw‑clamp terminations, clear circuit labeling, and a removable front connection that speeds up maintenance. If you’re landing a lot of field wires on high‑density discrete modules, this block typically saves space and reduces wiring errors.

Key Features

• 32‑point barrier terminal layout – Organized screw terminals for high‑density RX3i discrete I/O, which typically keeps panels tidy and serviceable.
• Removable front connection – You can unplug the block to replace a module without disturbing field wiring; you might notice downtime drops a lot in real plants.
• Screw‑clamp reliability – Secure terminations for industrial vibration environments; in many cases it reduces intermittent faults compared with loose spring inserts.
• Field‑friendly labeling – Channel numbering aligns with GE IC694 I/O faceplates, helping techs cross‑check circuits quickly.
• Finger‑safe design – Barrier style provides added separation between terminals for safer handling during commissioning.
• No external power required – Purely a field‑wiring interface; signals and commons are routed through the mated I/O module.

Related or Supporting Products

• IC694TBX132 – Spring‑clamp (box‑style) 32‑point terminal block; preferred where tool‑less wiring and vibration resistance are priorities.
• IC694MDLxxx (32‑pt discrete I/O) – RX3i digital input/output modules that the IC694TBB132 typically mates with; pick specific voltage and sourcing/sinking type per loop design.
• IC695CHSxxx (RX3i racks) – Backplanes and power supplies that host the I/O modules using this terminal block.

Installation & Maintenance

• Panel/cabinet – Install modules in a grounded industrial cabinet (EN 61010/EN 61131 compliant). Maintain adequate ventilation; avoid mounting near high‑heat sources.
• Wiring practice – Use ferrules where site standards require. Separate low‑level I/O and high‑voltage cabling. Tighten screws evenly; typical torque ~0.5–0.6 N·m works well in many cases.
• Module mating – Seat the terminal block firmly on the IC694 module until the latch engages. A gentle pull test helps confirm proper seating.
• Safety – De‑energize circuits before servicing. Label field conductors and verify channel mapping against the RX3i module’s faceplate.
• Routine checks – Quarterly visual inspection for loose strands, discoloration, or vibration‑induced loosening. Re‑torque terminals during scheduled shutdowns.
• Documentation – Keep the wiring diagram updated; from my experience, that single habit prevents most commissioning surprises.

Quality & Certifications

• CE and UL Listed for industrial control equipment (RX3i family)
• RoHS compliant materials
• Manufacturer warranty practices align with GE industrial standards; our supply warranty: 365 days

A quick note from a site supervisor we worked with: “Swapping an RX3i module without disturbing the field wires used to be a headache. With the TBB132, the changeover was under 10 minutes.” That seems to be the typical experience when moving to these barrier‑style blocks.
