The 1771-OAD is a high-performance digital output module from the Allen-Bradley PLC-5 family, engineered for precise control in demanding industrial environments. This module provides 16 isolated 120V AC outputs, ideal for switching loads such as contactors, motor starters, and indicator lights. With its robust construction and optical isolation, the 1771-OAD ensures reliable operation even in electrically noisy settings, making it a trusted choice for manufacturing, process control, and material handling systems. Each output channel features a dedicated LED for quick diagnostics, and the module supports standard PLC-5 backplane communication for seamless integration. Whether upgrading an existing system or building a new automation network, the 1771-OAD delivers consistent performance and long service life.
