The 65-233-900-HI plug-in module is part of a scalable high voltage switch platform that provides a high voltage switching solution with capability up to 9 kV.

Switch arrays are created by populating the 65-200-002 scalable chassis with plug-in modules that provide access to the switches on 51-pin front panel connectors. Users can specify as many or as few plug-in modules as they require and can field upgrade the chassis to extend the number of switches.

A hardware interlock is provided on the front panel connector that prevents relay operation if a suitably wired mating connector is not fitted. This can, for example, be used to disable relay operation if the test system cabinet door is open.

The chassis supports up to 6 plug-in modules which are loaded into the chassis via the front panel, greatly improving flexibility and ease of maintenance.
