Allen-Bradley 1794-OA16 16-Channel Analog Output Module

The Allen-Bradley 1794-OA16 is a 16-channel analog output module for Rockwell Automation's Flex I/O, designed to provide independent output signals to field devices such as proportional valves, variable‑speed drives, and process actuators. Each of the 16 channels offers an analog output with 0–10 V and/or 4–20 mA ranges depending on the model, enabling precise multi‑channel control across a Flex I/O network. The module interfaces with a Flex I/O backplane and can be mounted on a DIN rail or in a control panel, making it suitable for I/O expansions, retrofit upgrades, or replacement of failed output cards within Rockwell systems. Applications span process control, water and wastewater treatment facilities, HVAC/building automation panels, packaging and bottling lines, chemical processing, and material handling equipment where reliable analog outputs regulate valve positions, motor speeds, and continuous control loops. It aligns with the Allen-Bradley ecosystem and is commonly used as a replacement option alongside modules such as 1756-OA16, 1769-OF4, and 1734-OE8 in compatible Flex I/O configurations.
