CD Control Card DC Input
For DC input, the input signal is wired into Pin 2 (+) and Pin 3 (-) of the input
signal connector. An input signal of 3-30VDC turns the QPAC power control
ON. 0-1VDC turns the power control OFF.
CD Control Card Contact Closure Input
For a contact closure input to the CD Control Card, the contact is wired to pins
1 and 2 (+) of the input signal connector. A closed contactor input turns the
QPAC ON and an open contact turns the QPAC OFF. The input impedance is
10KΩ minimum.
