This is the MI12 Interface #A-2075-0142.

The standard MI12 unit is contained within a free standing enclosure with an optional panel mounting kit also available. The MI12 interface processes signals between one or two optical transmitters (OMMs) and the CNC control. The MI12 interface is required for use with Renishaw optical probes using Legacy transmission. The MI12 converts signals received from the OMM receiver into an acceptable form for the CNC machine control. This interface has solid state relay outputs.
