Wiring Connections for the Terminal Base Units
Distribution Boards for the 1794-TB37DS and 1794-TB62DS D-Shell
Terminal Bases
The distribution boards mount on the terminal base and provide multiple
input/output ports. By using the distribution boards, you can use individual
wiring for each of the channels. Refer to
Table 3 for application information on
the distribution boards.
