ACR1200 MOTHERBOARD JUMPERS
Digital Input Reference Select (JP15)
This jumper selects the reference voltage to be used for the optically-isolated inputs. The
reference voltage selected applies to all inputs; there are no combinations available.
Isolated voltage (VEXT) refers to +24VDC
WARNING
Wiring VEXT with the incorrect voltage will permanently
damage the Digital I/O circuitry. The isolated voltage
(VEXT) is selected as +24VDC.
Refer to Figure 1 for jumper location.
