Description
📋 Product Overview
The RELIANCE 0-60023-3, also identified as B/M-60023-3, is an AC Power Technology module associated with the Reliance Electric AutoMax Distributed Power System and SA3000 drive architecture.
Rockwell Automation documentation identifies B/M-60023 as the AC Power Technology module in the PMI rack. In the SA3000 high-power arrangement, the module works with the adjacent AC Parallel Interface module, while the medium-power configuration connects the AC Power Technology module directly with the AC power module.
The exact eBay listing identifies the unit as “RELIANCE 0-60023-3 AC POWER TECHNOLOGY B/M-60023-3.” The listed condition is Used, with the seller note “Remove from a working machine.”

The exact electrical ratings should be verified against the drive and module documentation for the particular installation. Publicly available sources do not provide enough evidence to safely assign generic input-voltage, output-current or power-consumption values specifically to this exact 0-60023-3 assembly.
🔌 Operating Function
The AC Power Technology module sits between the drive control architecture and the power section.
In the SA3000 system, the module handles the interface associated with the AC power module. The Power Module Interface connection is used to receive drive feedback information and transmit gate-driver signals. A front-panel LED provides an indication that the conditions required for firing signals to the power devices have been met.
The front panel also includes a Synch Transfer connection. Rockwell’s rack documentation shows the AC Power Technology position with terminals associated with synchronized transfer and a separate Power Module Interface connection.
This makes the module important when troubleshooting the relationship between the PMI control section and the drive’s power stage.
🏭 System Application
SA3000 Medium-Power Drives
The four-slot PMI rack includes:
- B/M-60007 — Power Supply
- B/M-60021 — PMI Processor
- B/M-60031 — Resolver & Drive I/O
- B/M-60023 — AC Power Technology
This arrangement is documented by Rockwell Automation for the SA3000 distributed power system.
SA3000 High-Power Drives
The eight-slot rack adds an AC Parallel Interface module and multiple Gate Driver Interface modules. In this configuration, B/M-60023 does not connect directly to the AC Power Module; it connects through the adjacent Parallel Interface module.
The Parallel Interface module allows the AC Power Technology module to communicate with multiple Gate Driver Interface modules and conditions/splits the associated signals for parallel power units.
🔧 Installation & Configuration
Because this is part of a legacy drive power-control system, replacement should be handled as a system-level maintenance task rather than simply swapping a generic circuit board.
Recommended procedure
- Record the complete part number from the existing module.
- Confirm whether the system is an SA3000 medium- or high-power configuration.
- Photograph all connectors and wiring before removal.
- Verify the rack slot designation.
- Confirm the adjacent modules, especially the AC Power Module or Parallel Interface module.
- Isolate and discharge the drive according to the applicable service procedure.
- Inspect the replacement board for corrosion, damaged connectors, cracked components or contamination.
- Install the board in the correct rack position.
- Reconnect the Synch Transfer and Power Module Interface connections as documented for the specific system.
- Check the “OK” indication after controlled power-up.
- Review drive diagnostics before returning the equipment to production.
Do not use the module’s physical similarity to another Reliance 0-60023-series board as proof of interchangeability. Related numbers such as 0-60023-1, 0-60023-4 and 0-60023-5 have different documented functions or revisions.
🧰 Maintenance Recommendations
Visual inspection
Check the PCB for:
- Burn marks
- Cracked components
- Oxidized terminals
- Damaged connectors
- Loose hardware
- Contamination
- Signs of overheating
The 0-60023-3 contains components on both sides of the PCB and includes a backplane connector, integrated circuits, capacitors, resistors, transistors and other discrete components.
Connector inspection
Pay particular attention to the Power Module Interface connector and Synch Transfer terminals. Poor connections in this section can produce symptoms that appear to originate from the drive power stage.
Status LED
The front-panel green “OK” indicator is useful during commissioning and troubleshooting. If the expected indication does not appear, check the complete drive-control chain rather than immediately assuming the board itself has failed.
Spare-parts management
For an operating legacy SA3000 installation, keeping a tested matching spare can be useful because this is an obsolete drive-system component. Third-party automation inventories continue to list 0-60023-3 as legacy Reliance hardware.
❓ FAQ
What is Reliance 0-60023-3?
It is an AC Power Technology / Power Module Interface board used in Reliance AutoMax and SA3000 drive systems.
Is B/M-60023-3 the same identification?
Yes. B/M-60023 is the module identification used in the AutoMax/SA3000 rack documentation, while 0-60023-3 is the board/part-number identification used by Reliance-related references.
Is it a PLC CPU?
No. It is associated with the AC Power Technology section of the drive’s PMI rack, not the PMI processor. The PMI processor is separately identified as B/M-60021.
What does the Power Module Interface do?
The interface connects the AC Power Technology module with the drive power section and carries drive feedback and gate-driver signals.
What condition is the eBay unit?
The supplied listing states Used, with the seller note “Remove from a working machine.”
Can another 0-60023-series module replace it?
Not automatically. The 0-60023-1, 0-60023-3, 0-60023-4 and 0-60023-5 are not interchangeable simply because their numbers are similar. Verify the exact drive configuration and revision before substitution.

📝 Application Summary
The RELIANCE 0-60023-3 / B/M-60023-3 is a specialized component of the AutoMax / SA3000 distributed drive system. Its role is centered on the AC Power Technology interface between the PMI control architecture and the drive power section.
For replacement purchasing, the most important checks are the complete part number, rack type, SA3000 power configuration, neighboring modules and connector arrangement. The supplied eBay unit is listed as used and reportedly removed from a working machine, so its actual condition should still be evaluated before installation.
