Product Overview

The Allen-Bradley 1794-OE4 serves as a high-density, distributed analog solution for the Flex I/O platform. It provides four non-isolated, single-ended outputs that interface directly with actuators, variable frequency drives (VFDs), and proportional valves. This module reduces wiring costs by allowing I/O to be placed closer to the field devices via a communication adapter. We supply this unit as 100% Brand New and Original in factory packaging, ensuring full compatibility with your existing Flex I/O terminal bases.

Engineering Advantages

Modular Scalability: The 1794-OE4 snaps onto a variety of terminal bases (such as the 1794-TB2 or 1794-TB3), allowing you to mix and match digital and analog signals on the same DIN rail. This eliminates the need for large, centralized racks and significantly reduces panel space requirements.
High-Resolution Precision: Utilizing a 16-bit data format, this module generates highly granular signals. This precision allows for smooth ramping in motion applications and fine-tuned control in chemical dosing or pressure regulation.
Flexible Signal Configuration: Engineers can configure each channel independently for voltage or current via software. This versatility means a single 1794-OE4 part number covers almost any analog actuator requirement, simplifying your spare parts inventory.
Rugged Distributed Architecture: Built for the plant floor, the Flex I/O design withstands the vibrations and electrical noise found in industrial environments. By placing the 1794-OE4 at the machine level, you minimize long runs of sensitive analog cables, which inherently reduces EMI/RFI interference.

FAQs

What terminal base is compatible with the 1794-OE4?

The 1794-OE4 works with several terminal bases, but most engineers prefer the 1794-TB2, 1794-TB3, or 1794-TB3S. The TB3 and TB3S provide additional terminals for common and power connections, which simplifies wiring for 2-wire and 3-wire field devices.

Does the 1794-OE4 support "Hot Swapping"?

Yes, the Flex I/O system supports Removal and Insertion Under Power (RIUP). You can replace a 1794-OE4 module without stripping power from the rest of the Flex I/O backplane or stopping other modules in the same rack, provided you follow industrial safety procedures.

Can I drive a 750-Ohm load on the current output?

Yes. When supplied with a stable 24V DC source, the 1794-OE4 drives resistive loads up to 750 Ohms on its current (mA) outputs. Ensure your external power supply remains within the 24V DC nominal range to maintain this performance.

Is this unit a new series or a discontinued version?

We sell only New & Original stock. While Rockwell Automation continuously updates firmware and series letters (e.g., Series A to Series B), our current stock represents the latest available factory versions, ensuring full support for modern Logix5000 and older PLC-5/SLC 500 controllers.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
