B&R MCGE31-0 — MULTI/MIDI Interface / Coupling Module
The B&R MCGE31-0 is a module from B&R’s MULTI / MIDI
control system range. Unlike the EC…-prefixed MULTI/MIDI modules, the MC… prefix identifies a distinct B&R module series, and the MCGE… type is documented in B&R’s module listings. It slots into a MULTI /
MIDI rack alongside the controller, power supply and I/O modules. Manufactured by B&R
(Bernecker & Rainer), Austria. Typically used as a maintenance and retrofit spare for
existing installations.

MCGE…module series (MULTI / MIDI system)- Slots into B&R MULTI / MIDI racks
- Related to the MC… module family
- Legacy maintenance / retrofit spare
- Manufactured by B&R, Austria
Key Features & Functions
MULTI / MIDI Module
Functions as a plug-in module within a B&R MULTI / MIDI rack system, working alongside the controller and I/O modules.
Rack Integration
Designed to slot directly into B&R MULTI / MIDI modular racks, connecting to the system backplane.
MC… Module Family
Part of B&R’s MC… module series, a distinct naming group alongside the EC… modules in the same system.
Industrial Construction
Built for continuous operation inside industrial control cabinets and process environments.

Source note: The MCGE… type is corroborated by B&R’s module listings for
the MULTI / MIDI system, and a matching entry for MCGE31-0 was found. A
specific connector/coupling function has been associated with this type, but the precise
technical role, channel count and electrical ratings were not confirmed
from an official B&R datasheet — verify these before purchase.
Typical Application Scenarios
- System Module: providing a plug-in function within a MULTI / MIDI rack assembly.
- Machine & Plant Control: serving as part of the module set in industrial control cabinets.
- Legacy System Maintenance: keeping existing Multicontrol installations running with genuine spares.
- Retrofit & Repair: replacing failed modules in established systems.
- Spare Part Replacement: servicing MULTI / MIDI systems in the field.
Frequently Asked Questions
What is the B&R MCGE31-0?
It is a B&R MULTI / MIDI module from the MCGE… series, designed to slot
into a MULTI / MIDI rack system.
How does it differ from the EC… modules (ECNT43-0, ECPE82-2, etc.)?
Both belong to the B&R MULTI / MIDI system, but they use different naming series
(MC… vs EC…). Confirm exact compatibility and the module’s
function in official documentation before substitution.
What is the module’s function?
The precise technical role should be confirmed against the official B&R datasheet — do not assume a function from the type code alone.
Which systems is it compatible with?
It is designed for B&R MULTI / MIDI racks. Confirm the exact rack configuration and system revision against official 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.
