M series distributed IO

For demanding applications

The M series is the natural choice for demanding applications in rugged environments with extreme temperatures, vibrations, etc. The M series features multiple certificates for marine and hazardous locations. Hot swap and redundancy makes the M series suitable for mission-critical applications, where continuous operation is crucial.

Upgrade a standard IO node to an advanced CODESYS-based control solution by simply replacing the network adapter with a CODESYS controller module and you will have a powerful compact controller solution.

The M series is the perfect choice of rugged high-end distributed IO.
