B&R ECPE84-2 — PE84 Power Supply Module
The B&R ECPE84-2 (type PE84) is a power supply module for B&R’s MULTI / MIDI rack systems (Multicontrol family). It provides a regulated DC supply to the rack backplane, powering the central controller and the plug-in I/O modules of the system. Like the other modules in this family, it is used to keep older B&R MULTI / MIDI installations operating and is a common maintenance and retrofit spare part. Manufactured by B&R (Bernecker & Rainer), Austria.
- Power supply module for MULTI / MIDI racks
- B&R type: PE84
- Supplies regulated DC power to the backplane
- Part of the Multicontrol module family
- Common legacy maintenance / retrofit spare
Key Features & Functions
Rack Power Supply
Supplies a regulated DC voltage to the rack backplane, powering the central controller and plug-in I/O modules of the system.
MULTI / MIDI Rack Integration
Designed to slot directly into B&R MULTI and MIDI modular rack systems alongside the controller and I/O modules.
Diagnostic / Status Indication
Front-panel status indication supports monitoring of the supply state, as is typical of the PE-series modules in this family.
Industrial Construction
Built for continuous operation inside industrial control cabinets and process environments.

Source note: The identity (B&R PE84 power supply module for the MULTI / MIDI rack family) is corroborated across distributor and parts-listings. The exact output voltage and current rating, input range and fuse data vary between reseller pages and were not confirmed from an official B&R datasheet — verify these before purchase. As with other modules in this family, some reseller pages carry mislabelled “controller” or “Ethernet module” descriptions; the reliable identity is the power supply module.
Typical Application Scenarios
- Rack Power Supply: supplying DC power to the backplane of MULTI / MIDI racks.
- Machine & Plant Control: powering controllers and I/O in industrial control cabinets.
- Legacy System Maintenance: keeping existing Multicontrol installations running with genuine spares.
- Retrofit & Repair: replacing failed or ageing power supply units in established systems.
- Spare Part Replacement: servicing power supply modules in the field.
Frequently Asked Questions
What is the B&R ECPE84-2?
It is a B&R PE84 power supply module designed for B&R MULTI / MIDI modular rack systems, supplying regulated DC power to the rack backplane.
What is the output rating?
The exact output voltage and current rating should be confirmed against the official B&R datasheet for the PE84 module.
Which systems is it compatible with?
It is designed for B&R MULTI and MIDI modular racks. Confirm the exact rack configuration and system revision against official documentation.
How does it differ from the ECPE82-2 / PE82?
Both are power supply modules for the same MULTI / MIDI rack family, but they are different module types (PE84 vs PE82) with different ratings. Do not substitute one for the other without confirming compatibility in official B&R documentation.
Where can I find the official datasheet?
Official technical documentation is available from B&R Industrial Automation and authorized distributors. Verify all specifications there before purchase.
