Overview
The Allen-Bradley 1746-OA16 is a discrete AC output module designed for the SLC 500 family of programmable logic controllers. This 16-point module provides general-purpose 120/240V AC outputs with an operating voltage range of 85-265V AC at 47-63 Hz. The module features removable terminal blocks and optical coupling for simplified installation and enhanced noise immunity.
Key Features
- 16 Digital AC Outputs: Sixteen (16) AC output channels in Two (2) groups of Eight (8) outputs each
- Removable Terminal Blocks: Eliminates the need to disconnect wires when replacing any of the modules
- LED Status Indicators: LED indicators that show output status values
- Filter Circuitry: Filter circuitry and optical coupling for signal noise reduction
- Rack-Mount Design: Single-slot chassis mounting with screw clamp terminals
- Compatible with SLC 500: May be installed as a local and remote I/O module of any SLC500 Programmable Logic Controllers (PLC) processor or CompactLogix and ControlLogix Programmable Automation Controllers (PAC)
