The following table describes the functions and characteristics of the pump
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 (-).
Function Characteristics
Available DC Power Supplies
+10 and -10
Protected against short circuits and overloads
2 outputs, +10 Vdc and -10 Vdc
Maximum current = 10 mA each
Digital Logic Inputs
DI5, DI6, DI7
