Product Description

Description

The Allen-Bradley 1746-OA16 is a reliable discrete AC output module designed for the Allen-Bradley SLC 500 modular hardware platform. This 16-point output module is engineered to control various AC-driven industrial devices such as motor starters, solenoids, and indicator lamps. Built for demanding automation environments, it provides optical isolation between the logic circuitry and the field-side AC supply to protect sensitive controller components from voltage transients.

Housed in a compact, single-wide SLC 500 module chassis, the 1746-OA16 integrates internal surge suppression circuits to minimize electrical noise generated by inductive loads. It requires minimal backplane power and supports standard removable terminal blocks, simplifying wiring maintenance and system commissioning without disturbing field-side connections.

Features

  • 16 discrete AC output channels grouped for flexible wiring configurations
  • Operating voltage range of 85 to 265 VAC at 47 to 63 Hz
  • Optical isolation between backplane logic and I/O field circuits
  • Built-in surge suppression for enhanced reliability against inductive load switching transients
  • Removable terminal block design for easy installation and maintenance
  • Status LED indicators per point for fast diagnostic troubleshooting

Applications

  • Controlling AC industrial actuators, solenoids, and control valves
  • Interface module for pilot lights and operator alarm horns
  • Switching fractional horsepower AC motor starters and contactors
  • Discrete logic control in manufacturing, packaging, and material handling systems

Connections / Interfaces

The 1746-OA16 utilizes a standard Allen-Bradley removable terminal block (RTB) located on the front of the unit. Field wiring connects directly to the screw terminals of the RTB, allowing the module to be easily removed from the SLC 500 chassis without disconnecting field wires. Terminal groupings correspond to the internal output isolation structure.

Installation Guidelines

Ensure the SLC 500 chassis power is turned off before installing or removing the 1746-OA16 module. Insert the module into any available I/O slot in the SLC 500 chassis, taking care to align the rear card edge with the backplane connector. Secure the module using the top and bottom retaining screws. Verify all field AC wiring complies with local electrical codes and does not exceed the maximum voltage and current ratings.
