Allen-Bradley 1797-OE8 | FLEX Ex I/O Module with 8 Analog Outputs

Product Overview

The Allen-Bradley 1797-OE8 FLEX Ex I/O Module provides 8 analog outputs with a single-ended, non-isolated configuration. It supports a load range of 0–22 mA and voltage up to 11V, ensuring precise signal control in industrial automation systems.

Designed for harsh environments, the 1797-OE8 requires a NEMA-certified IP20 enclosure and 12 AWG stranded cables for safe power connections. The module includes 8 fault indicators and a single power indicator, providing clear visual feedback for monitoring and troubleshooting. Its compact design and lightweight construction (0.63 lbs / 0.28 kg) make integration into existing systems straightforward and convenient.

With a 13-bit resolution, the 1797-OE8 delivers highly accurate analog output signals suitable for control valves, actuators, and other analog-driven devices. Thermal dissipation is rated at 18.4 BTU/hr, and power consumption at the field-side reaches 6.3 W, providing stable performance with efficient energy usage.
