The IC694ACC310A is a GE Fanuc PACSystems RX3i blank slot filler module, used to cover an unused rack position rather than perform an electrical I/O function. The IC694ACC310 family is documented for RX3i baseplates and covers one slot.

Module 3: Technical Product Introduction

An open slot in an industrial PLC rack is more than a cosmetic issue. Dust, conductive debris, moisture, and accidental mechanical contact can reach the exposed rack area and compromise equipment maintenance. The GE Fanuc IC694ACC310A is a blank filler module designed for the PACSystems RX3i platform. It occupies an unused rack position and provides a physical barrier while maintaining the mechanical arrangement of the rack.

There is no control processor hiding behind the part number. The IC694ACC310A has no I/O points, no communication interface, no status LEDs, and no backplane current draw according to available technical listings. It covers one slot and can be used with RX3i standard and expansion baseplates, including 7-, 12-, and 16-slot standard racks and 5- and 10-slot expansion racks.

Module 4: Application Scenarios & Field Realities

• In an RX3i main rack with unused positions, the IC694ACC310A closes the vacant slot so the backplane area is not left exposed. This is particularly useful when the rack configuration has fewer I/O modules than the available positions.
• For expansion or remote rack installations, the same filler concept applies to compatible RX3i expansion baseplates. Verify the actual baseplate family before installation; the filler is intended for RX3i hardware rather than being a universal PLC blanking plate.
• Where cabinets are exposed to dust or conductive particles, leaving an empty module position open is poor maintenance practice. A filler module provides a physical barrier against contamination entering the vacant position.
• During cabinet refurbishment, retaining the original filler modules can also help preserve the intended mechanical layout. The part has no PLC program to download and does not participate in control logic.

Field Traps — Watch Out

1. Do not treat the filler as an I/O module.
The does not provide inputs, outputs, communications, or application processing. It exists to occupy and protect a vacant RX3i slot.

2. Revision identification matters for procurement.
Available parts records distinguish , IC694ACC310B, and other revisions. If the customer’s specification calls for revision A, quote rather than shortening the request to IC694ACC310.

Installation note: The filler is mechanically simple, but it still needs to seat correctly in the RX3i rack. Confirm the module guides and retention mechanism are clean and undamaged. Some documentation indicates that the IC694ACC310 can be inserted or removed under power; however, site electrical procedures and the actual rack configuration should take precedence.

Module 6: Quality Assurance SOP

For , QA is primarily an identification and mechanical-integrity process because this is a passive filler module.

• Part-number verification: Confirm on the physical identification label.
• OEM anti-counterfeit visual inspection: Check GE Fanuc markings, part number, revision designation, molded housing, and manufacturing identifiers.
• Revision verification: Confirm Series A / Revision A where specified.
• Mechanical inspection: Check the housing, module guides, locking/retention features, and connector-side interface.
• Contamination inspection: Verify that the filler is free from oil, dust, conductive debris, corrosion, and moisture residue.
• Dimensional verification: Confirm approximate dimensions of 140 × 130 × 35 mm against the applicable physical specification.
• Backplane inspection: Confirm that the module has no damaged contacts or foreign material that could interfere with rack installation.
• Insertion-fit test: Install the filler in a compatible RX3i test rack or representative mechanical fixture and verify correct seating.
• Power-on self-test (POST): Not applicable — the contains no active PLC electronics.
• Communication handshake verification: Not applicable — the filler has no communication circuitry.
• I/O verification: Not applicable — there are no I/O channels.
• Final inspection: Check physical fit, retention, identification label, surface condition, and packaging.
• Traceability: Record complete part number, revision, serial/manufacturing information where available, inspection date, dimensions if measured, and condition classification.

Procurement note: The correct description is GE Fanuc — RX3i Blank Slot Filler Module. It should not be marketed as a programmable controller or I/O module. Available technical records consistently identify the IC694ACC310 family as a passive filler used to cover unused RX3i rack positions.
