Auxiliary I/O Terminals accommodate current levels up to 8 A and voltage up to
264 V AC. Voltage transients up to 300 V AC will not cause damage.
Installing Auxiliary I/O Terminals
Auxiliary I/O Terminals are installed by inserting the tabs into the slots on the I/O
Carrier or Interposing Terminals and pressing downward. Screws can be
inserted through the panel-mount holes for added stability if needed.
Auxiliary Carriers must be installed on the I/O Carrier or Interposing Terminals
before connecting field wiring.
Wire Specifications for Auxiliary I/O Terminals
Wire specifications depend on the terminal type. For box-type or spring type
terminals, each terminal accommodates one solid or stranded AWG #14 (avg.
2.1mm
2
cross section) to AWG #22 (avg. 0.36mm
2
cross section) wire, or two
wires up to AWG #18 (avg. 0.86mm
2
cross section).
For barrier-type terminals, each terminal accommodates one or two solid or
stranded wires from AWG #22 (avg. 0.36mm
2
cross section) to AWG #14 (avg.
2.1mm
2
cross section).
Use copper wire rated for 90 deg C. When inserting two wires in the same
position, the wires must be the same size and type (solid or stranded).
