Product Overview

The Allen-Bradley 1734-OA4 provides high-voltage AC switching capabilities within the modular POINT I/O ecosystem. This module features four non-isolated, sourcing outputs specifically engineered to control 120V or 220V AC field devices such as motor starters, solenoid valves, and indicator lamps. We supply this unit as 100% Brand New and Original, ensuring high-speed switching and long-term durability in distributed automation architectures.

Engineering Advantages

Robust Triac Switching: The 1734-OA4 utilizes triac-based output technology. This solid-state design eliminates the mechanical wear associated with traditional relays, providing millions of switching cycles for high-duty AC loads.
High Surge Capacity: Industrial loads like solenoids often draw significant inrush current. This module handles surges up to 16 A for 100 ms, preventing nuisance trips and module failure during device startup.
Space-Optimized High Voltage Control: At only 12mm wide, the 1734-OA4 allows you to integrate 240V AC control directly into the POINT I/O rack alongside low-voltage DC modules. This hybrid capability reduces the need for large, separate AC interposing relay panels.
Enhanced Safety Isolation: The module provides reinforced insulation tested at 3250V DC for 60 seconds. This design protects the backplane and sensitive logic-side components from high-voltage field-side transients.
Flexible Mounting: The module snaps directly into 1734-TB, 1734-TBS, or 1734-TOP wiring bases. This modularity allows for "wiring first, module later" installation and supports rapid "hot-swap" replacement via RIUP (Removal and Insertion Under Power).

FAQs

What is the minimum voltage required for the 1734-OA4 to operate?

The module requires a minimum on-state voltage of 74V AC. It will not reliably switch or maintain the output state if the supply voltage drops below this threshold.

Can I use the 1734-OA4 to switch DC loads?

No. Triacs only turn off when the AC current crosses zero. If you use this module with a DC load, the output will turn on but will stay "latched" on indefinitely, potentially damaging the module or the connected equipment. Use a 1734-OB or 1734-OV module for DC applications.

Does this module require a specific keyswitch position on the terminal base?

Yes. You must set the terminal base keyswitch to the correct position specified in the 1734-OA4 installation manual (typically Position 8 for AC modules) to prevent the accidental insertion of low-voltage DC modules into a high-voltage AC wired base.

How many outputs can I use at full capacity simultaneously?

Each channel supports up to 0.75 A, but you must ensure the total module current does not exceed the thermal dissipation limits of your specific cabinet configuration. Always verify the aggregate current draw against the POINT I/O power supply capacity.
