Description

Product Overview

The TOSHIBA 2N3A3110-C is a controller board used in Toshiba/TMEIC industrial automation and drive-control equipment. Available industrial references identify the unit as a PC board assembly and controller board, with the equivalent TMEIC designation ARND-3110. It is also associated with the 2N3A8204-B control-board family in installed equipment.

This type of board provides control and processing functions within a larger industrial control architecture rather than operating as a standalone PLC. Its application is therefore dependent on the host machine, firmware, connected boards, and system configuration. For maintenance teams supporting legacy Toshiba or TMEIC equipment, retaining the exact board revision and associated assembly information is important when sourcing a replacement. The part is reported as discontinued by the manufacturer, making verified replacement stock particularly relevant for installed-base maintenance.

Technical Specifications — 2N3A3110-C

Supplier and industrial inventory records list 2N3A3110-C as a Toshiba controller board, with a reported shipping/component weight of approximately 1.35 lb.

Key Features and Benefits — 2N3A3110-C

• Dedicated controller-board architecture for Toshiba/TMEIC industrial equipment.
• Designed for integration with proprietary machine-control hardware.
• Suitable for legacy equipment where the original control architecture must be maintained.
• Associated with the ARND-3110 designation in TMEIC equipment inventories.
• Board-level replacement can avoid unnecessary replacement of an entire control assembly.
• Useful as a critical spare for long-life industrial drive and automation systems.
• Compact PCB construction allows installation within the original equipment chassis.

A historical automation catalog lists the same part number as a TMEIC communication/controller-related board, while other industrial references identify it specifically as a controller board.

Installation and Maintenance — 2N3A3110-C

Before replacement, record the complete part number, board revision, serial number, installed firmware information, connector positions, and associated board numbers. Confirm the host equipment model and control configuration before removing the existing assembly.

Use appropriate ESD protection when handling the PCB. Inspect edge connectors, mounting hardware, terminals, and visible components for corrosion or mechanical damage. After installation, verify controller initialization, communication with associated boards, system diagnostics, and machine operation according to the applicable Toshiba/TMEIC service procedure.

Because this is a legacy proprietary controller board, physical fit alone does not establish compatibility. Personally, I would verify the associated ARND designation and installed equipment configuration before approving a replacement.

Product Warranty — 2N3A3110-C

Warranty coverage depends on supplier, product condition, and purchase agreement. For critical automation spares, request clear board photographs, revision information, serial-number traceability, functional-test status, and warranty terms before procurement.

The TOSHIBA 2N3A3110-C is best managed as a configuration-specific legacy controller-board spare. Its discontinued status makes exact identification especially important when maintaining existing Toshiba/TMEIC equipment.
