Allen-Bradley 1769-L30ER Compact I/O Output Module is a Rockwell Automation device that adds discrete output points to a 1769 Compact I/O system, enabling control of external actuators and indicators from a PLC. The unit is shown with firmware version 1.002 (F 1.002) as pictured. In typical 1769 Compact I/O installations, this module interfaces with the controller to switch outputs that drive relays, contactors, lamps, or other load devices managed by the PLC program.
