About M-Modules™

I/O for the Real World

M-Modules™, ANSI-standardized since 1997, are a mezzanine standard perfectly suited for adding any kind of real-world I/O to the system in a flexible way. They are modular I/O extensions for all types of industrial computers, from embedded systems up to high-end workstations. The simple, cost-effective architecture of the M-Module™ interface results in an optimum cost-per-channel ratio.

Typical M-Module™ functionality comprises instrumentation, process I/O, motion, robotics, various general-purpose analog and binary I/O as well as all common fieldbus interfaces.

Capabilities of M-Modules™

The board space provided for components allows to implement complex instrumentation functions and the space provided for connectors guarantees protection of sensitive signals.

The M-Module™ interface - a fast asynchronous parallel interface - offers sophisticated functions like 32-bit data bus, burst transfers up to 100 MB/s, DMA and trigger capabilities.

M-Modules™ offer direct front-panel connection rather than requiring a separate adapter panel with ribbon-cable connections. This provides a clean path for sensitive signals without loss of data or signal quality - using, for example, shielded D-Sub connectors and COAX cables.

A carrier board in double Eurocard format can accommodate up to four M-Modules™, for instance in a CompactPCI® or VMEbus system.

Rugged and Industrial - As Always

MEN boards have been developed to work also in rugged environments - qualified or screened regarding shock, vibration, drop, resonance, humidity, chemicals, and up to -40 to +85°C operating temperature.

M-Modules™ have a long-term availability of minimum 10 years (and longer according to individual agreements).

An Established Standard

MEN has not only invented M-Modules™, but has also developed around 100 different M-Modules™ out of a variety of more than 350. Further manufacturers of M-Module™ products can be found on the websites of industry organizations such as VITA, PICMG and others.

The ANSI/VITA 12-1997 (R2002) standard defines minimum mechanical and electrical characteristics of M-Modules™.
