Overview of Allen-Bradley 1797-OE8H

The Allen-Bradley 1797-OE8H is a FLEX Ex HART analog output module designed for the Flex I/O 1797 product line. Manufactured by Rockwell Automation, this module provides robust data communication capabilities for industrial environments, specifically supporting eight single-ended output points.

As part of the FLEX Ex system, the 1797-OE8H is engineered to meet the requirements of hazardous area installations, offering a reliable interface for controlling field devices in demanding process control applications.

Key Features

This module features a high-precision 13-bit resolution, ensuring accurate analog signal output for connected devices. The outputs are single-ended and non-isolated, which simplifies wiring configurations in specific system architectures.

The 1797-OE8H supports Removal and Insertion Under Power (RIUP), allowing for maintenance and module replacement without shutting down the entire system, provided the work is performed in non-hazardous areas. It is designed to be mounted on a DIN rail, with grounding possible through the rail if it is made of zinc-plated yellow chromate steel.

Performance and Capacity

The module provides eight analog output channels with a load range current of 0 to 22 mA. The load range voltage is rated at 15 V at 22 mA. Power consumption on the field side is approximately 6.1 W, with a power dissipation rating of 5.4 W and a thermal dissipation of 20.8 BTU/hr.

Operating conditions include a temperature range of -20 to 70 degrees Celsius (-4 to 158 degrees Fahrenheit) and a storage temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The module can tolerate 5 to 95% relative humidity in both operation and storage, provided there is no condensation. The unit weighs approximately 200 g (0.75 lbs).

Installation and Compatibility

The 1797-OE8H is compatible with the FLEX Ex I/O system and is intended for use with the 1797-TB3 and 1797-TB3S terminal base units. It is certified for use in Zone 1 and Zone 22 hazardous areas, adhering to UL, C-UL, and CENELEC standards as detailed in the FLEX Ex System Certification Reference Manual.

Installation requires mounting on a DIN rail. While the module supports RIUP, it is recommended to disconnect backplane power and all connected input and output devices before removal to ensure safety and data integrity.

Applications and Industries

Designed for process control applications in hazardous environments, the 1797-OE8H is suitable for industries such as oil and gas, chemical processing, and pharmaceuticals where reliable analog output control is critical in explosive atmospheres.

The module's HART compatibility and high-resolution output make it ideal for integrating with smart field devices that require precise control signals in complex industrial automation systems.
