Information About 1794-OE4

The 1794-OE4 is part of the Allen-Bradley Flex I/O family, developed for modular and distributed I/O solutions. It supports four configurable output channels that can provide 0–20 mA, 4–20 mA, ±10 V, and 0–10 V signals, with 12-bit resolution plus sign. The module integrates with Flex I/O communication adapters such as 1794-ACN15, -ACNR15, -AND, -AENT, and -AENTR, and can also connect to controllers like ControlLogix or MicroLogix through remote adapters. Compatible with terminal bases including 1794-TB2, -TB3, -TB3S, -TB3T, -TB3TS, and -TBN, it allows easy DIN rail mounting and wiring. The unit operates on a 24 VDC supply, offers diagnostic LED indicators, and requires no calibration. Designed for reliable performance, it ensures accurate analog control in a wide range of industrial environments.

Key Features:

  • Output Channels: Four single-ended analog outputs for current and voltage.

  • Signal Ranges: 0–20 mA, 4–20 mA, ±10 V, and 0–10 V.

  • Resolution: 12-bit plus sign, with 2.56 mV/cnt (voltage) and 5.13 µA/cnt (current).

  • Compatibility: Works with Flex I/O terminal bases 1794-TB2, -TB3, -TB3S, -TB3T, -TB3TS, and -TBN.

  • Networking: Integrates with Flex I/O adapters for Ethernet, ControlNet, Profibus, and Remote I/O.

  • Diagnostics: Built-in green/red status LED for module health and operation.

  • Power & Isolation: Operates at 24 VDC, with 50 V isolation between I/O and system.

  • Performance: Fast conversion rate of 1.024 ms for all channels, with step response of 24 ms.

The 1794-OE4 delivers the reliability and precision required for process control and distributed I/O applications in industrial automation.

Frequently Asked Questions about 1794-OE4
Question: What types of analog output signals does the 1794-OE4 support?
Date Update:02/06/2025
Answer:

This module supports multiple output signal types, offering flexibility for different control applications. Supported outputs include:

  • 0 to 20 mA current output, commonly used for analog instrumentation.
  • 4 to 20 mA current output, a standard for process control.
  • +/-10V DC voltage output, useful for driving devices that require bipolar voltage.
  • 0 to 10V DC voltage output, often used for standard analog signaling.

This variety ensures compatibility with a wide range of industrial equipment and processes.

Question: What is the resolution of the 1794-OE4 module, and why is it important?
Date Update:02/06/2025
Answer:

The 1794-OE4 module features a 12-bit resolution plus sign for both voltage and current outputs. For voltage, this corresponds to 2.56 mV per count, and for current, 5.13 µA per count. This resolution allows for precise control of analog devices, such as variable frequency drives, valves, or other actuators. High-resolution output ensures smooth and accurate modulation of processes. Accurate control improves overall system performance and product quality.

Question: Which terminal bases are compatible with the 1794-OE4 module?
Date Update:02/06/2025
Answer:

The 1794-OE4 is designed for installation with the following Flex I/O terminal bases:

  • 1794-TB2
  • 1794-TB3
  • 1794-TB3S
  • 1794-TB3T
  • 1794-TB3TS
  • 1794-TBN

These bases provide the necessary electrical connections and mechanical support. Each base offers different wiring and grounding options depending on system needs. Selecting the correct terminal base ensures proper installation and reliable operation. These bases also enable easy module replacement and maintenance.

Question: How should the 1794-OE4 module be installed in a Flex I/O system?
Date Update:02/06/2025
Answer:

The 1794-OE4 module should be installed properly to ensure safe and reliable operation. Recommended steps include:

  • Mount the appropriate terminal base (e.g., 1794-TB2) securely on the DIN rail.
  • Slide the module onto the terminal base and lock it in place.
  • Connect the external 24V DC power supply within the specified voltage range.
  • Wire the output terminals according to the application’s requirements and observe proper grounding.

Following these steps helps maintain signal integrity and system reliability.

Question: Does the 1794-OE4 module remain in production and available for purchase?
Date Update:02/06/2025
Answer:

Yes, the 1794-OE4 is currently in an Active Mature lifecycle status. This means it is still available for purchase and supported by Rockwell Automation, although it may be nearing the later stages of its product lifecycle.
