Wiring - Facility Explorer - Part No. 24-11064-00013 - DX-PCA-Adapter - Field Device

Most connections come pre-terminated through the use of the wiring harnesses. These connections are shown as a reference in Figure 1.

Communication wiring must be terminated directly to the PCA. Power input wiring is required for the PCA in addition to the existing power input wiring used for the base of the DX controller.

Figure 1. Wiring connections

The replacement controller has fewer I/O terminal points than the original DX controller, so an additional terminal block is located on the under-side of the circuit board to accommodate the extra points Figure 2 . This additional terminal block allows for every termination used on the DX controller to be used with the adapter assembly if desired.

Note: For most applications, you may use the existing DX mounting base terminal blocks as a termination point for jumper wiring to bring these extra points (Table 1) to PCX modules. This is a simpler solution that does not require terminations to be made to the additional terminal block under the adapter, which have to be made prior to connecting the adapter to the DX base, and are not accessible after installation.

Note: The position of the PCA3613 controller on the base adapter may be different than what is shown.

Note: TB1 is referenced on the circuit board to help determine I/O position and is not a termination.
