The 40-664A-001 is a high power switching module configured as a four channel multiplexer. It is capable of switching inductive/capacitive loads up to 40A at 14VDC.

The multiplexer is suitable for switching heavy loads or for slave switching large external relays, contactors and solenoids. In particular these relay modules are designed for automotive test applications requiring the switching of DC voltage at high current.
The 28V version is suitable for truck system test applications. The Module is fully compliant with PXI and cPCI specifications and occupies two 3U slot positions. Connection to the relays is made via a front panel high power D-type connector..
