Wiring Examples with Auxiliary Terminal Blocks

If the module is installed on an I/O Terminal Block with Box Terminals or an I/O Terminal

Block with Barrier Terminals, an Auxiliary Terminal Block may be required to provide

additional wiring terminals. For the I/O Terminal Block with Wire to Board Connectors,

external connection points are usually be preferred, although an Auxiliary Terminal Block

can be used..

Auxiliary Terminal Blocks have all terminals connected together internally. The Auxiliary

Terminal Block with box terminals has 13 terminals, each of which accommodates one AWG

# 14 (avg 2.1mm2 cross section) to AWG #22 (avg 0.36mm2 cross section) wire, or two wires up

to AWG #18 (avg. 0.86mm2 cross section). The Auxiliary Terminal Block with barrier terminals

has nine terminals, each of which can accommodate one or two wires up to AWG #14 (avg

2.1mm2 cross section).
