ABB UFC765AE102 (3BHE003604R0102) – High-reliability Controller/communication Board for ABB Symphony/Advant Harmony DCS

• Warranty: 365 days

• Delivery: typically 1 week if in stock; not more than 1 month at the latest

• Payment: 50% advance; full payment before delivery

• Express Options: FedEx, UPS, DHL

• Packaging: ESD-safe, foam-protected, sealed for transit

• Direct replacement form-fit – Designed as a like-for-like replacement for UFC765AE102 (code 3BHE003604R0102) to minimize re-engineering.

• Backplane-powered design – Draws power from the system backplane, so no external PSU wiring is needed in most cases.

• Stable operation in legacy cabinets – Typically used in ABB Symphony/Advant Harmony racks where consistent timing and comms are critical.

• Service-friendly swap – Front-access installation helps shorten outage time; technicians often perform changeover within a standard maintenance window.

• No direct field I/O – Functions as a controller/communications element; field wiring remains on existing I/O modules.

• Lifecycle support – Suits installed-base sustainability programs where a controlled, low-risk replacement is preferred over a full DCS migration.

Plants keep the UFC765AE102 in service where deterministic control and legacy compatibility matter. Typical use-cases include:

• Power generation: turbine and balance-of-plant loops within Symphony/Advant racks

• Oil & gas: compressor stations and reformer units relying on established Harmony nodes

• Pulp & paper: machine section control where downtime windows are tight

• Chemicals & petrochem: legacy DCS cells requiring low-risk replacement parts

Customer feedback (typical): “Swapped the board during a night shift, system re-joined without rework. Saved us a day of troubleshooting.”

• Risk reduction – Form-fit replacement helps avoid unplanned engineering changes.

• Compatibility – Aligns with ABB Symphony/Advant Harmony architecture; no field wiring disturbance.

• Cost control – Extends installed-base life; defers full system migration costs.

• Supportability – We assist with part identification, revision matching, and pre-shipment verification.

• Cabinet environment – Keep within typical 0–55°C, non-condensing; ensure steady ventilation and clean power to the rack PSU.

• ESD handling – Use wrist straps and antistatic packaging; avoid touching component leads.

• Wiring – No changes to field wiring; seat the module firmly in the backplane connectors and secure any front-edge service leads.

• Routine checks – Inspect connectors for oxidation, clean dust with dry air, and verify firmware/parameter alignment with the controller set (if applicable).

• Spares strategy – In many cases, plants keep one tested spare per critical rack to reduce MTTR.

• CE-marked industrial control component (series-dependent)

• Manufactured under ISO 9001 quality systems

• UL/cUL considerations typically apply at the system level for the complete DCS rack

• RoHS status may vary by production period; documentation available on request

If you need help confirming revision compatibility or matching firmware for your cabinet, share a photo of the nameplate and the host rack details. One thing I appreciate about this series is how predictable the interchangeability is when revisions are matched correctly—it saves real time in the field.
