ACR1200 MOTHERBOARD JUMPERS
Digital Output Sink/Source Select Jumpers (JP20 and JP21)
These jumpers are set at the factory based on the type of the output drivers, IC’s U67 and
U73. The selected type of the output driver applies to all outputs; 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 +24VDC.
Selecting the wrong jumper settings for the type of output
drivers installed on the board will permanently damage the
output driver IC’s (U67 and U73). The output drivers are
installed at the factory, based on the Sinking or Sourcing
Option selected when ordering the board.
Refer to Figure 1 for jumper location.
