maximize productivity.
Digital I/O modules are available with 4, 8, 16, or 32 channels and in a wide variety of
I/O voltages (including AC, DC, and TTL). Combination modules with 2 inputs/2
outputs, 4 inputs/4 outputs, and 6 inputs/6 outputs are also available.
Terminals on the 4, 8, 12, and 16-channel modules have self-lifting pressure plates that
accept two 14 AWG (2 mm2) wires. LED indicators on the front of each module display
the status of each I/O point.
32-channel I/O modules are equipped with a 40-pin, MIL-C-83503 type header and a
removable wiring connector (1746-N3). The connector can be assembled with the wire
type and length of your choice.
Output modules are available with solid-state AC, solid-state DC, and relay contact type
outputs. High current solid-state output modules, catalog numbers 1746-OBP16, 1746-
OVP16, and 1746-OAP12, have fused commons with a blown fuse LED indication. The
Step 1 - Select:
• I/O modules – available in a
variety of densities and voltage
options. Some modules have
diagnostic features, individually
isolated inputs/outputs or
electronic protection.
• interface modules (IFMs) or
prewired cables (optional)
Publication 1747-SG001E-EN-E - February 2013
1746-OB16E, 1746-OB6EI, and 1746-OB32E modules provide electronic protection
from short circuit and overload conditions.
Wiring of 16 and 32-channel modules can also be accomplished with a bulletin 1492
interface module and pre-wired cable. All 16-channel I/O modules and catalog numbers
1746-OX8, 1746-OBP8, 1746-OAP12, 1746-IO12 are equipped with color-coded
removable terminal block
