Selecting SLC 500
I/O Modules
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 pre-
wired cables (optional)
Digital I/O modules, analog I/O modules, and specialty temperature, counting,
process control, and BASIC language modules are available to help you create a
custom solution for your application.
1746 Digital I/O
Modules
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 mm
2
) 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, -
OVP16, and -OAP12, have fused commons with a blown fuse LED indication. The
1746-OB16E, -OB6EI, and -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, -OBP8, -OAP12, 1746-IO12 are equipped with color-coded
removable terminal blocks.
