Product Overview

The Allen-Bradley 1794-OE4 is a Flex I/O 4-point analog output module, part of the Flex I/O platform. It provides four single-ended outputs, configurable for voltage or current, and communicates over the Flexbus through a terminal base. It is typically used in control systems to drive analog field devices such as actuators, valves, or instruments. The module integrates into industrial automation applications requiring mixed I/O, modular expansion, and analog output capability. 1794-OE4 integrates with Flex I/O assemblies and is widely applied in machine-level control, process systems, and distributed I/O architectures.
