1769DA

1769-DA is a part number in Rockwell Automation's 1769 Compact I/O family, used to designate a four-channel analog output module. The module provides four analog outputs that can be used to drive actuators such as valves or motors. Depending on the specific variant, each channel can operate as a voltage output (commonly 0-10 V) or a current output (commonly 4-20 mA), with isolation between channels to help protect the controller from fault conditions.

The 1769-DA is installed in a Compact I/O chassis and communicates with a programmable logic controller via the 1769 backplane bus. Configuration and programming are performed with Rockwell's software, including RSLogix 5000, Studio 5000, or equivalent, depending on the controller model and firmware. Typical applications include process control, analog actuation, and real-time control loops. Performance characteristics such as output range, resolution, and accuracy depend on the exact revision of the module; users should consult the product user manual and compatibility charts for precise specifications.

The designation 1769-DA has become a recognized catalog label for these analog output modules within the Rockwell Automation ecosystem, and similar modules have evolved with new form factors in later generations of Compact I/O.
