Power Interface Card Eyes UUT Assignments

Designed as a low-cost method of powering a unit-under-test (UUT), GT7404 power output interface uses the GTXI Carrier Card form-factor to output four voltage levels of 5V, 12V, -5V and -12V from the backplane via a DB25 connector to the front panel for easy user interfacing. Each of the four power channels provides computer controlled relay for ON/OFF function, a user replaceable fuse for overcurrent protection, a current and voltage monitoring that measures the voltage drop across an on-board four-wire resistor, and an optional UUT discharge component.
