ABB HITE303166R1 / HITE515100 / IDB761A – Distributed Control Board | AC800M DCS Platform
Engineering Background
The ABB AC800M is ABB’s flagship distributed control system (DCS) platform, widely deployed in power generation, oil & gas, pulp & paper, and chemical process industries. The HITE303166R1 / HITE515100 / IDB761A is a core control board assembly within this platform, responsible for inter-module communication, I/O signal arbitration, and real-time process data routing between the controller CPU and field I/O modules.
Product Positioning
This board is a direct replacement and spare part for existing AC800M installations. It is sourced from decommissioned or surplus industrial systems, fully inspected, and verified for functional integrity before listing. Procurement engineers managing aging DCS infrastructure will find this a cost-effective alternative to new OEM supply with lead times of 16–26 weeks.

- Traceability: Full documentation package available on request (test report, photos, serial number record)
System Architecture & Signal Flow
Within the AC800M rack architecture, the IDB761A board interfaces directly with the PM8xx controller module via the internal ModuleBus backplane. It manages signal arbitration between the CPU and downstream S800 I/O modules, handling both digital and analog signal conditioning. The HITE515100 sub-assembly provides the physical layer interface for optical or copper Ethernet communication to the plant network, while HITE303166R1 is the primary PCB carrier integrating both functions.
Signal flow: Field Instruments → S800 I/O → IDB761A (via backplane) → PM8xx CPU → Plant DCS Network
Sourcing & Quality Verification

Technical FAQ
Q: Is this a new or refurbished part?
A: This is a tested surplus unit. It is not new OEM stock. Condition is clearly stated as Used/Surplus – Tested & Verified.
Q: Will this work with my AC800M firmware version?
A: The IDB761A is hardware-compatible across AC800M generations. Firmware compatibility depends on your PM8xx controller version. Contact us with your system details for confirmation.
Q: Can you provide a test report?
A: Yes. A pre-shipment test report and photographic record are available upon request at no additional charge.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days from Xiamen, China. DHL Express delivery to most destinations: 3–7 business days.
Q: Do you accept returns?
A: Yes, within 30 days of receipt if the unit is found to be non-functional on arrival and the issue is confirmed by our technical team.
