Allen-Bradley 1771-OAN PLC-5 Digital AC Output Module

Product Description

Configured for AC discrete output control in Allen-Bradley PLC-5 systems, the Allen-Bradley 1771-OAN (1771-OAN Digital AC Output Module) provides direct electrical switching for field-connected AC loads. The module provides 32 source-type outputs arranged in four groups of eight and operates with 120/240 VAC output circuits. It installs in a compatible 1771-A1B chassis or later chassis version and supports half-slot addressing without restrictions or 1-slot addressing with restrictions.

Hardware Specifications

PLC-5 Backplane and I/O Density Characteristics

The 1771-OAN operates as a discrete output interface within the Allen-Bradley PLC-5 architecture. Its 32 output points provide I/O density scaling through four electrical output groups, while the 1771 chassis backplane supplies the module interface required for PLC system operation.

The module uses source-type AC outputs and therefore requires compatible sink-type field input circuitry. In addition, the selected addressing method must match the PLC-5 chassis configuration. Half-slot addressing operates without the stated restrictions, whereas 1-slot addressing requires the applicable addressing restrictions to be observed.

Frequently Asked Questions

Q: How many field outputs does the 1771-OAN provide?
A: The 1771-OAN provides 32 AC digital outputs arranged in four groups of eight outputs.

Q: What wiring arm is used with the 1771-OAN?
A: The module uses the Allen-Bradley 1771-WH wiring arm for field wiring connections.

Q: Can the 1771-OAN operate with any AC field circuit?
A: The module is specified as a source-type output module rated for 120/240 VAC operation. It must be connected to compatible sink-type input circuitry and wired according to the applicable PLC-5 installation requirements.

Field Installation Guidelines

Install the 1771-OAN only in a compatible Allen-Bradley 1771-A1B chassis or an applicable later chassis version. Verify the chassis addressing configuration before inserting the module, especially when using 1-slot addressing.

Disconnect or isolate applicable system power before installing or removing the module unless the complete system installation procedure specifically permits the required operation. Install the 1771-WH wiring arm correctly and secure field conductors to prevent terminal movement.

Route AC output wiring separately from low-level analog and communication cables where practical. Maintain proper conductor insulation ratings for the connected voltage and load circuit. Inspect field wiring for correct source and sink relationships before energizing the output circuits.

Confirm that the total connected load remains within the specified 8 A maximum module current rating. Finally, verify output operation and switching response after system commissioning.
