Allen Bradley 1734-OA4 POINT I/O Digital AC Output Module

Product Description

The Allen Bradley 1734-OA4 is a POINT I/O digital AC output module that switches AC loads through four discrete output channels. It supports 120 or 220 V AC output and has a total output current rating of 2 A. The module also specifies a maximum power dissipation of 3.5 W, making these electrical ratings important when checking load requirements and cabinet thermal conditions.

Technical Specifications

Output Configuration and Load Requirements

The 1734-OA4 provides four discrete AC output channels for switching external loads. Its output voltage rating identifies the supported AC voltage levels, while the 2 A total current rating must be considered when evaluating the combined load on the module. The supplied specifications do not establish an individual current limit for each channel.

POINTBus Power and Thermal Conditions

The module draws 75 mA from the POINTBus and has a maximum power dissipation of 3.5 W. Its specified maximum thermal dissipation is 11.69 BTU. These values help engineers assess the module's bus power demand and heat contribution when checking the overall I/O assembly.

Frequently Asked Questions

Q: How many output channels does the 1734-OA4 provide?

A: It provides four digital AC output channels for switching external loads.

Q: What is the total output current rating?

A: The supplied specifications list a total output current of 2 A. Confirm the permitted current per channel and the applicable load restrictions before connecting field devices.

Q: What electrical ratings should be checked before replacement?

A: Verify the required AC voltage, output channel count, total and per-channel load current, POINTBus current demand, and thermal limits. The stated 120 or 220 V AC rating and 74 V AC on-state voltage should also be checked against the applicable technical documentation before commissioning.
