Each channel connects to the power bus via a Form C SPDT
(single pole, double throw) relay. This relay has a NO
(normally-open) and a NC (normally-closed) terminal. Each NO
terminal is connected to a pin on J4-J7, and each NC terminal is
connected to a pin on J8-J11. Each pin on J8-J11 can be
connected to any of the four power bus lines on J12 via jumper
wires. See
Figure
5-27.
The terminal block jumper allows convenient connection of
pull-up or pull-down voltages to the various inputs. It also
allows for terminating a UUT load at a different voltage than
ground. For example, the channel could be connected to +12
volts on one side, and +5 volts on the other.
