Control Board | SDCS-CON-2A 3ADT309600R0002 | ABB

Technical Specifications

The ABB SDCS-CON-2A  3ADT309600R0002 is a drive control board  primarily used in ABB's mid-range Variable Frequency Drive (VFD) and Direct Current Systems (DCS), specifically platforms such as the DCS500 and early ACS800/ACS580 series. It handles power conversion processing and acts as the main control unit for DC drive systems.

Troubleshooting & Comissioning Checklist

EEPROM Transfer: You must migrate the original drive's software PROM chips (or download the system-specific firmware) onto the new board's IC sockets.
Grounding Shield: Confirm that the board's mounting screws are tightened to secure a solid electrical reference ground.
Control Voltage Check: Energize only the auxiliary power (typically 24VDC/115VAC). Verify that the on-board status LEDs light up and the Drive Control Panel (HMI) initializes.

Field Engineering Considerations

Bare Hardware Shipping: This board is distributed as raw hardware without pre-installed firmware or software. Attempting to drop it straight into a machine will result in a non-functional drive.
Firmware Flashing: Field engineers must manually flash the specific application firmware corresponding to the target drive profile using ABB-authorized engineering tools before commissioning.
Jumper Configuration: The physical PCB features hardwired jumper blocks (e.g., coding zones for feedback scaling, analog input types, and termination resistances). Field techs must match the jumper positions of the new board exactly to the unit being replaced.

Technical FAQ

Q: What drive systems is this board compatible with?
A: It is widely used in the DCS500 and DCS600 series. It is also noted for having better compatibility with newer ACS 880 drives compared to legacy boards like the SDCS-CON-1A.

A: While it features upgraded fiber-optic bandwidth and thermal stability compared to the SDCS-CON-1 series, it is not directly replaceable with non-ABB modules due to proprietary communication protocols.

A: It is extensively used in high-demand industrial environments such as oil refineries, water treatment plants, mining operations, conveyor systems, and large-scale HVAC control.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
