The following table describes the functions and characteristics of the pump
switching option card control terminals.
switching option card control terminals.
NOTE: There is no +24 Vdc power supply output on this option card;
therefore, it is necessary to connect an external +24 Vdc power source
between terminals DO+ (+) and COMDI (-).
