ABB 086339-001 | Drive I/O Board, In Stock, Fast Shipping

Description

Product Introduction

The ABB 086339-001 is an I/O extension board designed for the ACS800 series variable frequency drives. This board mounts directly into the drive control unit, providing additional digital and analog input/output capability beyond the standard I/O included on the drive main control board. Typical applications include external start/stop control, speed reference signals, feedback monitoring, and integration with plant automation systems.

The ACS800 drive platform is one of ABB’s most widely installed AC drive families, with hundreds of thousands of units in operation across industries including HVAC, material handling, pumps, fans, and conveyors. The 086339-001 is a standard option board that expands the drive’s connectivity for applications requiring more I/O than the base drive provides. As ABB has transitioned to the ACS880 platform, the ACS800 product line and its associated option boards have been discontinued. For facilities still operating ACS800 drives, sourcing replacement I/O boards is essential for maintaining system functionality.

Key Technical Specifications

Key Selling Points & Differentiators

• ACS800 Direct Replacement: Designed specifically for ABB ACS800 drives. Drop-in replacement for failed or damaged 086339-001 boards. No drive programming changes required when replacing with the same part number.
• Expanded I/O Capacity: Adds 6 digital inputs, 3 relay outputs, 2 analog inputs, and 1 analog output to the drive’s standard I/O. Critical for applications requiring more field device connectivity.
• Plug-in Installation: Mounts directly into the drive control unit with no additional wiring or mounting hardware. Field wiring connects to removable terminal blocks on the board.
• Programmable I/O: All I/O channels are configurable through the drive parameters, allowing adaptation to specific application requirements without hardware modifications.
• Authenticity Guarantee: Each unit undergoes visual inspection for ABB OEM markings, serial number traceability, and PCB integrity. We test every board on a live ACS800 drive before shipping.

Frequently Asked Questions (FAQ)

Q: Which ABB drives is the 086339-001 compatible with?
The 086339-001 is designed for the ABB ACS800 series drives. It is not compatible with ACS550, ACS880, or other ABB drive families. It mounts in the RMIO (I/O extension) slot on the drive control unit. If your drive does not have an available slot, you may need a different option board or an I/O expansion kit.

Q: Is this board discontinued?
Yes. ABB has phased out the ACS800 drive platform in favor of the ACS880 series. The 086339-001 is no longer in active production. Availability is limited to new surplus and tested used inventory. For ACS800 drives still in operation, we recommend securing spares while stock remains available.

Q: What is the difference between the 086339-001 and the UAD206A101?
Both are I/O extension boards for the ACS800 drive platform, and they are functionally similar. The 086339-001 and UAD206A101 share the same I/O count, specifications, and physical interface. The part number variation reflects different manufacturing periods or regional part number assignments. In most applications, these boards are interchangeable. We recommend matching your existing board part number for a direct replacement, but if only one variant is available, it will typically function identically.

Q: Does this board require additional configuration after installation?
The board is automatically recognized by the drive when installed. However, the I/O functionality must be configured through the drive parameters. For example:

• Parameter 10.xx for digital input functions
• Parameter 15.xx for analog input scaling
• Parameter 14.xx for relay output assignments

If you are replacing a failed board with the same part number and the drive parameters have not been changed, the new board will operate with the existing parameter settings.

Q: Can I install this board while the drive is powered?
No. The drive must be powered down and locked out before installing or removing any option board. The control unit backplane is not hot-swappable. Attempting to install or remove a board with power applied can damage the board, the drive control unit, or both.

Q: What are common failure modes for this board?
In our experience, the most common failures are:

• Field wiring shorts damaging input or output circuits
• Relay contact welding due to high inrush currents
• Corrosion on terminal blocks from moisture exposure
• Component failure from voltage surges on field wiring

We recommend installing proper surge suppression on inductive loads and maintaining clean, dry enclosures to extend board life.

Q: What testing do you perform before shipping?
We test every 086339-001 on a live ACS800 drive. Our test procedure includes:

• Visual inspection for physical damage, corrosion, or previous repairs
• Edge connector cleaning and inspection
• Drive communication verification (board recognized by drive)
• Digital input channel testing with simulated field signals
• Digital output (relay) testing with load simulation
• Analog input and output accuracy verification
• 24-hour continuous power-on soak test

A test report with channel test results is included with each shipment.
