I/O module wiring
Terminal blocks are installed to the front of the I/O modules for connecting field device wiring as shown in
Figure 11. Terminal blocks are color coded and numbered to identify the I/O module type. (See Table 6.)
The terminal blocks are removable so that I/O modules can be replaced without disconnecting the field
wiring from the terminal blocks. Wire gauge sizes 16 to 22 AWG can be used to connect to the terminal
blocks. The field wiring exits through rubber grommets at the top or bottom of controller enclosure. The
rubber grommets are removed by sliding the grommet forward with the terminal block and the attached
field wiring.
