MSI-m, MSI-mx

Modular Safety Interface Category 4

The modular safety interface MSI-m is used to temporarily suppress the safety function of protective devices during the transport of material (Muting).

The version MSI-mx allows two protective devices to be muted independently, and it enables safety switches or Emergency Stop command devices to be integrated.
