BFKK 1756-IA16 Power Adapter 16 Input 120V AC

SKU CH-E9YZ-FSZRP

16-input 120 V AC PLC module mounts on DIN rail and fits ControlLogix chassis with removable terminal blocks

  • 16 inputs across 8 groups for flexible signal monitoring
  • 74–132 V AC operating range suits standard 120 V supplies
  • .58 W backplane draw keeps chassis power budget low
  • Producer-consumer interface shares I/O status across multiple controllers
  • 125 V continuous isolation on removable terminal blocks protects field wiring

16-Input PLC Module for ControlLogix Systems

The BFKK 1756-IA16 is a 120V AC input module designed for Allen-Bradley ControlLogix chassis. It provides 16 discrete inputs organised into eight groups, making it suitable for industrial automation tasks that require monitoring multiple field devices. The module uses producer-consumer technology to share input status across multiple controllers.

Check Chassis Slot and Terminal Block Compatibility

Verify that your ControlLogix chassis has an available slot and that you have a compatible removable terminal block such as the 1756TBNH or 1756TBSH for field wiring. The module requires a 1492 interface module or similar connection method to link field-side devices. Ensure your backplane can supply the required 0.58 Watts of power.

Replaces Older 120V AC Input Modules

This module upgrades legacy 120V AC input cards by offering higher density with 16 points in a single slot. The jump is worthwhile when you need to reduce panel space or simplify wiring with the removable terminal block design. It is not for applications requiring DC input voltages or analog signal processing.

Questions about this item

What comes with the 1756-IA16 module and what must be purchased separately to connect field wiring?

The module includes complete installation instructions and a jumper bar for thermocouple modules. A removable terminal block such as the 1756TBNH or 1756TBSJH, or a 1492 interface module, is required to connect field-side wiring.

Which removable terminal block should I select for the 1756-IA16 given the 125 V isolation rating?

Both the 1756TBNH and 1756TBSJH terminal blocks are listed for this module and share a 125 V continuous isolation voltage, so either can be used for the 16-input 120 V AC application.

How much backplane power does the 1756-IA16 draw when installed in a ControlLogix chassis?

The module draws 0.58 W from the chassis backplane, which must be accounted for in the total power budget of the ControlLogix system.
