Key Technical Specifications

Product Introduction (No Fluff)

The ABB UAD206A101 (material number 3BHE019958R0101 / 3BHE019959P201) is a CPU mainboard module designed for ABB industrial control systems. It serves as a core processing unit, handling control program execution, data processing, and system-level communication within ABB PLC and DCS architectures.

Built with advanced circuit design and industrial-grade components, this module provides reliable, stable performance in demanding automation environments — power generation, petrochemical processing, steel mills, and other continuous-process industries. Its multiple connection options allow integration with various ABB controllers and field devices.

This unit is typically sourced as a replacement spare or for system expansion. Because UAD206 variants can appear across different ABB system generations, always con

firm the exact material number, revision, and system compatibility before ordering.

QA & Testing SOP (Dynamic & Transparent)

1. Label & Anti-Counterfeit Check
   Confirm the front label reads UAD206A101 and the material number matches 3BHE019958R0101 or 3BHE019959P201. Check for re-labeling, mismatched serial numbers, or altered revision markings.
2. ESD-Safe Handling
   Store and ship in anti-static packaging. CPU mainboards contain sensitive processor and memory components vulnerable to static discharge.
3. Connector & Edge Contact Inspection
   Inspect the backplane edge connector and front-panel ports for bent pins, oxidation, or mechanical wear. Poor backplane contact is a common cause of intermittent faults in older ABB racks.
4. Controlled Power-On Test (If Test Rack Available)
   If a compatible ABB chassis is available, install the module and perform a controlled power-on. Monitor LED status, initialization sequence, and thermal behavior. Abnormal heating near the CPU area is an immediate fail.
5. Communication & System Recognition Test
   If the host system or configuration tool is available, verify that the module is recognized by the controller, can communicate on the system bus, and loads firmware without errors.

Installation Pitfalls & Guide (Engineer to Engineer)

❗ Confirm the exact material number and revision. The UAD206A101 is associated with both 3BHE019958R0101 and 3BHE019959P201. Different material numbers can indicate different revisions or functional variants. Installing the wrong revision can prevent system recognition.

❗ Do not hot-swap this module. CPU mainboards manage active control tasks. Removing or inserting them while the system is running can cause process upsets, communication failures, or system crashes.

❗ Verify slot assignment and addressing. ABB control racks are configuration-sensitive. Installing the module in the wrong slot or with incorrect addressing can prevent the system from booting or recognizing the processor.

❗ Check backplane power stability. CPU modules draw significant power from the backplane. An unstable rack power supply can cause repeated resets or false faults.

Replacement Steps:

1. Pre-install: Back up the system configuration and project files. Confirm model, material number, slot assignment, and addressing.
2. Removal: Place the system in maintenance/stop mode. De-energize if required by your change management procedure. Release front-panel fasteners and withdraw the module straight out.
3. Install: Align the new module with the backplane guides. Seat it evenly — do not force. Secure the front fasteners.
4. Power-on Test: Restore power. Verify LED indicators and system recognition. Download configuration if needed. Run functional checks before returning to automatic mode.

Technical FAQ

1. Is UAD206A101 compatible with my ABB control system?
It belongs to the ABB control system family and is specified as a CPU mainboard module. However, compatibility depends on your exact rack generation, slot configuration, firmware version, and system architecture. Cross-check the material number against your installed base before ordering.

2. What is the difference between 3BHE019958R0101 and 3BHE019959P201?
Both material numbers are associated with the UAD206A101 model. The exact difference (revision, firmware, or functional variant) should be confirmed through ABB documentation or by comparing the label on your existing module. Do not assume interchangeability without verification.

3. Do you offer warranty on this unit?
Warranty terms depend on condition. New original stock typically carries stronger coverage than surplus inventory. Confirm warranty length and DOA terms before purchase.

4. Can I get flexible pricing for MRO or project orders?
Yes. Pricing for CPU mainboard modules depends on quantity, condition, revision, and lead time. For stocking orders or project procurement, request a quote with your required quantity and delivery date.

5. Is this model still supported by ABB?
The UAD206 family is used in ABB industrial control systems across multiple generations. Official lifecycle status should be confirmed through ABB documentation or your system integrator, especially for critical control applications.
