The remote I/O circuitry and connector are integral parts of the wiring
board in the 9/440HR system module.
Figure 5A.22 shows the location of the
remote I/O connector. This connector is mounted in the same location on
all Series 9/440HR wiring boards.
Wire connections for the remote I/O communications are made through the
TB4 NODE ADAPT connector. Connect the wires for remote I/O as
shown in the following figure. Refer to your 1771 I/O documentation for
details on making remote I/O connections.
