ACR8020 MOTHERBOARD JUMPERS
Digital Output Sink/Source Select Jumpers (JP15 and JP16)
These jumpers are set at the factory based on the type of the output drivers, IC’s U120
through U123. 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 (U120-U123). The output drivers are
installed at the factory, based on the Sinking or Sourcing
Option selected when ordering the board.
