Product Overview

The ABB 3BHE020570R1022​ is the material-numbered identifier for the PPD114 B1022, an AC 800PEC-series PEC Peripheral Device (PPD) engineered as an 8-channel analog output (AO) module within ABB’s AC 800PEC high-performance drive-control platform. The AC 800PEC itself is ABB’s drive-optimized Programmable Automation Controller—architecturally derived from the AC 800M but hardened and accelerated for demanding drive-control duties (rolling-mill main drives, marine pod propulsion, dynamometer test rigs, high-power converter stations for ACS6000/ACS5000). Within that rack, the PPD114 B1022​ occupies a peripheral slot to the right of the PM891-PEC / PM892-PEC CPU module, plugging into the AC 800PEC optical/high-speed backplane and delivering eight galvanically isolated analog output channels, each configurable for ±10 V voltage mode or 0/4–20 mA current mode, with 12-bit to 14-bit resolution depending on the PEC firmware and channel loading.

The “PPD” prefix denotes “PEC Peripheral Device”—the AC 800PEC rack’s I/O and interface slice family, which also includes PPD103 (digital I/O), PPD113 (analog input), PPD512 (high-speed digital/pulse), and others. The PPD114​ is the AO member of that set, and the B1022​ suffix is the hardware/index spin (B = base variant, 1022 = production index under 3BHE020570). Physically the ABB 3BHE020570R1022​ is a Eurocard-form, hot-swappable module with a plastic fascia carrying LED status per channel (active, fault, overrange), a 24 V DC backplane-powered design (no local P/S required—the AC 800PEC rack PSU feeds 24 V + 5 V through the backplane), and screw-terminal or spring-cage field termination on the rack’s frontal terminal block assembly (the PPD114 itself carries the electronics; field wires land on the PEC rack’s TB, which mates to the PPD through the backplane connector).

From a system perspective, the PPD114 B1022​ is the handoff point where the AC 800PEC’s drive-control algorithms (flux-vector, DTC, cyclic torque referencing, outer-loop speed/position PI) become real-world analog signals that go to the drive’s AFE/rectifier reference, to external chart recorders, to analog supervisory SCADA, or to secondary-loop hydraulic/pneumatic actuators in hybrid drive+aux systems. In a rolling-mill main-stand drive, for instance, the PEC CPU computes the torque reference at 4 ms task rate, pushes it to the PPD114 B1022​ AO channel as ±10 V, and that ±10 V feeds the ACS6000’s AFE torque-reference input—deterministic, low-latency, drive-grade. For plants running AC 800PEC racks inside ACS6000 cabinets, converter-test cells, or marine switchboards, the ABB 3BHE020570R1022​ is a top-rotation spare because AO modules see more thermal cycling (from the rack blowers in dense ACS6000 enclosures) and more channel-level stress (overrange events from commissioning torque steps) than pure-DI modules.

Technical Specifications

(Note: Exact resolution, accuracy, and update-rate depend on the PEC firmware revision and how the is mapped in the application (fast-task vs. slow-task). Always verify the white label on the removed module—3BHE020570R1022 / B1022—against your AC 800PEC rack’s BOM and CPU firmware before ordering.)

Main Features and Advantages

The ​ is purpose-engineered for the one job that generic PLC analog-output cards aren’t trusted with in high-power drive systems: delivering deterministic, low-noise, drive-grade analog references from a sub-10 ms control loop to a multi-megawatt converter front end. The first advantage is resolution + speed matched to PEC task rates. The AC 800PEC CPU (PM891-PEC / PM892-PEC) typically runs its drive-control task at 4 ms or faster for rolling-mill and marine propulsion loops; the ​ is mapped into that same task’s I/O scan, so the AO update trails the CPU’s torque/speed calculation by only the backplane-propagation + DAC settling time—sub-ms. Contrast this with a general-purpose PLC AO card on PROFIBUS DP (hit by the 12 Mbps bus cycle + master-scan jitter) or even PROFINET IRT on a non-drive-optimized rack—the PEC backplane is optical, deterministic, and prioritized for drive I/O. This matters when the AO is feeding a torque reference to an ACS6000 AFE and a 2 ms jitter translates to a visible stand-speed ripple on a tandem-mill bar.

Galvanic isolation and channel ruggedness​ is the second pillar. Each AO channel (or channel-pair group, depending on B1022 production batch) is galvanically separated from the backplane logic and from neighboring channels. In drive cabinets—where the PEC rack sits inches from IGCT/IGBT stacks switching at several kHz, and where the 24 V DC rack supply shares a cabinet with 690 V AC contactors and chopper resistors—this isolation keeps the AO signals clean. Each channel is short-circuit protected: if a field wire to the ACS6000 reference input gets nicked and shorts to PE, the ​ limits current and flags a per-channel fault LED + PEC diagnostic bit, rather than letting the DAC output stage cook. Overrange detection catches when the PEC CPU pushes a +10.5 V on a ±10 V channel (common during commissioning torque-step tests) and reports it upstream instead of clipping silently.

Hot-swap and rack integration​ make service low-friction. The ABB 3BHE020570R1022​ slides into the AC 800PEC rack’s PPD guide rails, seats on the optical backplane connector, and locks with the fascia clip—no field wires touch the PPD itself (all analog outputs land on the PEC rack’s frontal terminal block, which backplane-mates to the PPD). This means a swap is: unlock, withdraw, seat replacement, lock—under 3 minutes, and on PEC racks that support live-insert (most PM891-PEC / PM892-PEC racks do, with the CPU in RUN), you don’t even need a rack power-down for a single PPD. The PEC CPU detects the new PPD’s hardware ID (B1022) on the next I/O scan, re-establishes the channel mapping from the application download (which lives on the CPU’s CFast/SD, not on the PPD), and you’re back online. No rewiring, no re-download, no drive re-tune.

Lifecycle and spare-strategy value​ close the case. AC 800PEC was ABB’s flagship drive-control PAC for the 2010s–2020s window (before the newer AC 800M + OPC UA / Ability generations took over new projects), and it’s deeply embedded in /ACS5000 cabinets worldwide—rolling mills in Sweden/Germany/Japan, marine pod drives on cruise/ferry newbuilds, engine-test dynamometers for automotive OEMs. The ​ is among the top 5 most-cycled PPD spares (alongside PPD103 DI/DO, PPD113 AI, and the PM891-PEC CPU itself). For plants with 3+ AC 800PEC racks, keeping two 3BHE020570R1022​ on the shelf covers AO-channel failures across the fleet—far cheaper than an emergency 48-hour airfreight from Europe when a mill-stand’s torque-reference AO drifts during a campaign.

Application Field

The ​ is deployed exclusively inside AC 800PEC racks, which in turn sit inside ABB high-power drive systems and OEM test-rig control cabinets. The single largest habitat is metals rolling—hot-strip main stands, tandem cold mills, plate-mill screwdowns, and coiler drives built on + AC 800PEC. In a 5-stand tandem cold mill, each stand’s main drive has its own AC 800PEC rack; the PEC CPU runs flux-vector / DTC torque control at 4 ms, and the ​ outputs the torque-reference ±10 V (or 4–20 mA) to the AFE’s reference input, plus auxiliary AO channels to screw-down hydraulic pressure loops, coolant-pump VFD speed refs, or strip-tension outer-loop references that sit outside the drive but inside the PEC’s wider control umbrella. AO drift on the ​ here shows up as stand-speed asymmetry or tension variation—visible on the strip, so spare readiness is non-negotiable.

Marine propulsion​ is the second major vertical. Azimuth pod drives (ABB Azipod) and shaft-line drives on cruise ships, ferries, and offshore supply vessels use AC 800PEC for the pod’s converter control and the diesel-electric PEMS coordination; the ​ carries AO channels for torque reference to the pod’s IGCT converter, propeller-pitch actuator commands, and cooling-loop references. Marine classification (DNV, LR, ABS) requires redundancy and fast swap—hot-swap PPDs are part of that design. Engine and powertrain test dynamometers​ (automotive OEMs, EV-motor test, gearbox endurance) are the third: the AC 800PEC runs the dyno’s speed/torque control loop at sub-5 ms, the ​ sends the torque command to the absorber drive’s AFE and the speed command to the spindle drive, and also outputs real-time torque/speed to the test-cell’s data-acquisition rack via ±10 V for correlation with torque transducers and encoder dial gauges.

Retrofit and service scenarios are equally central. As AC 800PEC racks pass the 10–12 year mark, AO channels develop offset drift (DAC reference voltage ages, isolation amp CTR degrades) and the per-channel short-circuit clamps weaken. The ABB 3BHE020570R1022​ is the direct-fit B1022-index spare called out in ABB’s AC 800PEC service BOM; swapping it restores AO accuracy without touching the PEC CPU’s application code (lives on CPU storage) or the AFE parameters. For OEMs still supporting AC 800PEC fleets (mill-maintenance contractors, shipyard electrical teams, dyno integrators), the ​ is a default line item in every PEC PM kit alongside the CPU backup battery and the PPD103/PPD113 sibling modules.

One clarification worth embedding: the ​ is strictly AC 800PEC backplane—it will not plug into an AC 800M S800 rack, a Freelance rack, or a Procontrol P14 rack. Buyers sometimes cross-shop “PPD” across ABB platforms; only the AC 800PEC rack (PM891-PEC / PM892-PEC CPU, optical backplane, 24 V rack PSU) accepts the 3BHE020570R1022. Verify the rack nameplate says “AC 800PEC” before ordering.
