Product Overview

The 1756-OA16K is an Allen-Bradley ControlLogix module providing sixteen 120/240 VAC digital output points in a conformally coated design for enhanced protection in industrial control systems. It belongs to the 1756-OA16 family and interfaces via the ControlLogix backplane to drive AC loads such as relays, solenoids, or pilot lights. The module is mechanically fused per group, supports scheduled outputs, and is intended for application in ControlLogix racks where AC output points are required under elevated environmental stress.

Best Suited For

  • ControlLogix systems requiring AC outputs
  • Environments needing conformal coating protection
  • Applications with grouped fuse protection per 8-point group
  • Operations requiring scheduled or synchronized outputs
