Observe the following guidelines when wiring a PCA3613 controller.
Input and Output terminal blocks
The fixed input terminal blocks are located on the bottom of the controller, and the output terminal
blocks are located on the top of the controller. See Table 3 for more information about I/O terminal
functions, requirements, and ratings.
FC bus terminal block
The FC Bus terminal block is a blue, removable, 4-terminal plug that fits into a board-mounted jack.
Wire the removable FC bus terminal block plugs on the controller, and other controllers in a daisy-
chain configuration using 3-wire twisted, shielded cable as shown in Figure 4. For more information
about the FC Bus terminal function, requirements, and ratings, see Table 5.
