Connect the Field Output Device to the I/O Connector (P1)
The 1799-D16U16B and 1799-D16U16BL boards have outputs that supply current to
your field output device (sourcing outputs).
The outputs on these boards are isolated in two groups of eight, with each group
requiring 24V dc power and 24V dc ground. Outputs 0...7 are powered from +24V
GRP 0 and return power via GRP 0 Return. Outputs 8...15 are powered from +24V
GRP 1 and return power via GRP 1 Return.
Use these wiring diagrams to connect both groups of outputs on these boards.
1799-D16U16B and 1799-D16U16BL Outputs (sourcing)
The 1799-D16U16V and 1799-D16U16VL boards have outputs that receive current
from your field output device (sinking outputs). The outputs on these boards are in
two groups of eight, with each group requiring 24V dc power and 24V dc ground.
