Description

PPD113 (3BHE023584R2634) — AC 800PEC Processor Module

Product Overview

The PPD113, identified in ABB’s ordering system as PP D113 with the article number 3BHE023584R2634 and the configuration designation B03-26-100110, is the processor module of ABB’s AC 800PEC — the Power Electronic Controller that sits at the top of the company’s high-speed control range. Manufactured by ABB Switzerland Ltd, Power Electronics Systems in Turgi, the AC 800PEC is designed to combine the microsecond-level control demanded by power electronics with the slower process-control tasks usually assigned to a separate PLC, and the PPD113 is the unit that executes that work.

The board’s role in the system is unambiguous: it is the brain. It runs the current- and voltage-regulation loops of power converters, generates the pulse patterns that drive thyristor and IGBT power stages, and simultaneously executes supervisory logic, monitoring, and communication. ABB’s own documentation describes the processor as a fully featured 750 MHz RISC CPU with a 64-bit IEEE floating-point unit, optimized for very fast control cycles, with application code and data held in Flash memory — no battery backup required.

In practice, 3BHE023584R2634 is a critical, configuration-controlled spare: the PPD113 family spans multiple B-revisions and ten-digit suffixes that encode memory and FPGA configurations, and ABB’s documentation is explicit that compatibility must be checked against the system’s bill of materials rather than assumed from the family name. For a plant running ACS5000/ACS6000 drives, UNITROL 6000 excitation systems, static frequency converters, or HVDC/FACTS equipment, the correct PPD113 variant is one of the most important boards in the spare-parts cabinet.

Key Features and Advantages

A processor built for the microsecond world: The AC 800PEC is engineered for control cycles measured in microseconds — the regime where a standard PLC cannot keep up. The PPD113 runs fast tasks such as current regulation and pulse-pattern generation while handling slow tasks such as monitoring and communication, an architecture ABB designed specifically for power converters.

Deterministic execution where jitter is not an option: Power-stage switching tolerates no timing wander, and the PPD113 is built for it — executing control algorithms with predictable timing rather than the best-effort scheduling of an industrial PC. For a converter, this determinism is what keeps current loops stable and switching patterns correct under load.

FPGA-assisted signal handling: Integrated logic for ultra-fast I/O processing and pulse-width modulation generation offloads the timing-critical work from the CPU, letting the processor concentrate on regulation while the hardware handles the high-speed pattern generation — the division of labor that makes multi-megawatt converters controllable.

Optical isolation as standard practice: The front-panel fiber-optic ports provide complete galvanic isolation between the control electronics and the high-voltage power stage, which is not a refinement but a necessity in a converter cubicle where switching transients would otherwise corrupt copper-signal control links.

Flash-based operation, no batteries: Program and data reside in Flash memory, so the module retains its application through power loss without battery-backed RAM — one less consumable and one less failure mode in the cabinet.

Full platform integration: As the CPU of the AC 800PEC base system, the PPD113 works with the platform’s backplane, optical and communication modules, fast peripheral I/O, and standard ABB S800 I/O, and is programmed in Control Builder M plus MATLAB/Simulink — the same engineering environment that supports the whole control system, from high-speed loops to plant logic.

A defined spare with a defined footprint: The 3BHE023584R2634 carries its variant in the designation (B03-26-100110), and ABB documents that different suffixes mean different memory and FPGA configurations. Ordering the exact article number is the difference between a spare that drops in and one that will not run.

Application Areas

The PPD113 appears wherever control speed exceeds what a general-purpose PLC can deliver. In medium-voltage drives — the ACS 5000 and ACS 6000 families — it controls the converter bridges for pumps, compressors, marine propulsion, and blast-furnace blowers, where regulation bandwidth directly determines torque quality and protection performance.

In power generation, the AC 800PEC platform is the control heart of UNITROL 6000 excitation systems, regulating the field of large synchronous generators; the same platform drives static frequency converters that feed railway networks at their own frequency, and participates in HVDC and FACTS systems such as STATCOM, where grid stability depends on fast reactive-power response.

The module also serves the conversion stage of multi-megawatt wind turbines, controlling the generator-side and grid-side converters so power is injected smoothly into the grid, including fault-ride-through behavior. Across these applications the role of 3BHE023584R2634 is constant: execute the control laws at the speed the power hardware requires, hold them deterministic under transient conditions, and communicate the result to the wider plant control system.

Installation and Maintenance

Installation preparation: Before handling the PPD113, de-energize the controller subrack and confirm the power stage is discharged and locked out. Verify the incoming module’s full designation — article number 3BHE023584R2634, B-revision, and the ten-digit variant code — against the system’s bill of materials, because PPD113 variants with different suffixes are not interchangeable by footprint alone. Fit the module into the AC 800PEC backplane using the guide rails so the connector seats squarely, and observe ESD precautions throughout — this board is static-sensitive. Check the fiber-optic connectors for cleanliness before insertion; contaminated optics are the classic cause of communication-lost faults. After seating the module, verify the firmware version against the rack’s other modules, since ABB’s system will refuse to enter Run state on a version mismatch to protect the power hardware.

Maintenance advice: Use the front-panel LEDs as the first health indicator — Run (green), Warning (yellow), Fault (red) — and investigate any warning state rather than clearing it. Keep the subrack’s fan unit in service, since the PPD113 relies on vertical airflow for cooling. Back up the application software through the AC 800PEC toolset over the Ethernet service port before any hardware replacement, and store the backup with the maintenance records. Clean fiber-optic interfaces only with an appropriate optical cleaner, and keep a verified spare 3BHE023584R2634 in anti-static packaging, confirming its variant matches the installed unit’s BOM before it is ever fitted.

Product Warranty

The PPD113 (3BHE023584R2634) is supplied as a new or verified-surplus processor module with warranty covering materials, workmanship, and functional testing. Because the PPD113 family spans multiple B-revisions and configuration suffixes, each unit should be verified against the system’s bill of materials — article number, variant code, and firmware baseline — before acceptance into spares stock. The AC 800PEC is a documented, long-lifecycle ABB platform with ongoing spare availability and support from ABB’s Power Electronics division in Turgi, so 3BHE023584R2634 can be sourced as a tested, traceable replacement, with application guidance covering variant selection, firmware matching, and commissioning — keeping the converter’s control brain operational for the life of the power plant or drive system.
