More Information

Overview Manuals I/O Assignment Relay Protection Power-up Check Application
  • Six 120 V AC input points
  • Six relay output points
  • Mixed input and output functions in one SLC 500 slot

1746-IO12 combines six 120 V AC inputs and six relay outputs in one SLC 500 chassis slot. This mixed-I/O arrangement can reduce slot use in compact machines.

The inputs operate from 85–132 V AC. The relay contacts support documented AC or DC load circuits, but circuit voltage, current, inrush, and suppression must be checked against the installation manual.

The removable terminal block assists service replacement, but wiring must be identified before transfer. During startup, illuminated output indicators do not by themselves prove that field outputs are energized.

Availability, condition, price, and shipping time for 1746-IO12 are confirmed during quotation.

  • Six 120 V AC input points share the documented input common arrangement
  • Six relay outputs occupy the separate output section of the module
  • Input terminals and relay contacts must be mapped independently in the SLC 500 program
  • Check the actual AC or DC load before selecting the relay output circuit
  • Evaluate contact inrush, switching duty, and connected suppression
  • Keep field protection and relay commons consistent with the wiring diagram
  • Output indicators may appear active before processor control is established
  • Verify field voltage independently from the module LEDs
  • Confirm removable-terminal wiring before transferring conductors
  • Compact mixed AC input and relay output control
  • Legacy SLC 500 machine maintenance
  • Replacement of a verified 1746-IO12 installation
Description
Allen-Bradley 1746-IO12 is a combination AC input and relay output module for SLC 500 control systems.

The module provides six 120 V AC inputs arranged as six points per common and six relay outputs rated for 5–265 V AC or 5–125 V DC switching.

Before installation or replacement, confirm field-voltage compatibility, relay-load requirements, backplane loading, removable terminal-block wiring, and the module’s maximum heat dissipation within the enclosure.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can Allen-Bradley 1746-IO12 be installed in an existing SLC 500 rack without changing the program?
Not automatically. The input and relay-output points occupy different parts of the I/O image, so the slot configuration, addresses, terminal assignments, and field wiring must be checked before energizing the rack.
Are the relay contacts of Allen-Bradley 1746-IO12 suitable for coils and solenoids?
They may be used only when the load and switching duty are compatible. Contactors, solenoids, and other inductive loads may require external suppression or an interposing relay to limit arcing and contact damage.
Does a replacement Allen-Bradley 1746-IO12 include the removable terminal block?
Do not assume the terminal block is included. Confirm the seller’s supply scope and compare the existing block, keying, conductor labels, commons, and terminal condition before transferring wiring.
Why can Allen-Bradley 1746-IO12 output LEDs illuminate during startup?
Rockwell notes that output indicators may illuminate for several seconds at power-up or while the rack is not under processor control. Confirm actual field voltage before diagnosing an energized output.
Can the terminal block be moved directly to a replacement Allen-Bradley 1746-IO12?
Only after the catalog number, terminal identification, keying, conductor labels, commons, and load voltages are verified. Isolate power before transferring the removable terminal block.
What should be documented before replacing an Allen-Bradley 1746-IO12 in a live machine?
Record the input commons, relay-load wiring, processor image, terminal labels, suppression components, and startup sequence before removing the original module.
Can Allen-Bradley 1746-IO12 be replaced by 1746-IO8 without changes?
No direct substitution should be assumed. The point count, image mapping, terminal assignments, wiring, and program references differ and must be engineered before conversion.
