Allen-Bradley 1794-OF8IH

Overview

The Allen-Bradley 1794-OF8IH is an 8-channel isolated analog output module from the Flex I/O family, designed to support HART communication on each channel. It outputs 4–20 mA analog signals and provides galvanic isolation between channels to prevent signal interference. This module is ideal for process control applications requiring both analog signal output and field device communication via HART protocol.


Key Features

  • Channel Count: 8 analog outputs

  • Signal Type: 4–20 mA current output

  • Protocol: HART (Highway Addressable Remote Transducer)

  • Isolation: Channel-to-channel isolation

  • Voltage Supply: 24V DC

  • Mounting: Flex I/O system base (DIN rail)

  • Status Indicators: LED diagnostics per channel

  • Configuration: Via Studio 5000 or RSLogix 5000

  • Output Resolution: 16-bit

  • Compatibility: Integrates with ControlLogix, CompactLogix, and other Flex I/O adapters


Technical Specifications

  • Catalog Number: 1794-OF8IH

  • Series: Flex I/O

  • Output Range: 4–20 mA

  • Resolution: 16-bit

  • Output Accuracy: ±0.1% full scale

  • Update Rate: 1 ms per channel typical

  • Power Supply: 24V DC

  • Isolation Voltage: 250V (channel-to-channel)

  • Certifications: UL, CE, CSA, ATEX (Zone 2)

  • Operating Temp: 0°C to 55°C (32°F to 131°F)

  • Enclosure: Open-style module for use in enclosures

  • Brand: Allen-Bradley

  • Sub Brand: Flex I/O


Applications

  • Distributed process control systems

  • Analog valve and actuator control

  • Field device integration using HART

  • Oil & gas, chemical, water treatment industries

  • Hazardous location I/O (Zone 2 rated)


Why Choose the 1794-OF8IH

  • Combines high-accuracy analog output with HART communication

  • Isolated channels reduce crosstalk and enhance reliability

  • Ideal for modular, space-saving Flex I/O installations

  • Seamless integration with Logix5000 platforms
