It is possible to close more than one channel at a time. Since the
trace from P2 to J41 can only carry 30 Amps, the total current of all
the channel must be less than or equal to 30 Amps.
The Agilent N9377A dual-load load card lets you use the same
channel to test of shorts to ground and Vbatt or tests that
require two types of load for different parts of the test. The card
provides current sense, pull-up/down, and flyback protection.
The card also provides Card Type, Card Configuration, and
Status readback of the built in relay timers. See
Agilent E6178B 8-Channel Load Card"
Unless otherwise noted, writing a 1 closes (energizes) a relay,
and writing a 0 opens (de-energizes) the relay. The reset and
power-on state for all relays is open.
The block diagram in Figure shows the location of the various
registers.
