The Allen-Bradley 1769-OG16 is a compact TTL output module designed for efficiency and flexibility, featuring 16 outputs with precise voltage-dependent state guarantees. With a current range from 0.15 to 24 milliamps per point, it is engineered for versatility and mounts easily onto DIN rails, panels, or integrated with other 1769 modules. Despite its compact dimensions of 4.7 x 1.4 x 3.4 inches, users should ensure protection against environmental factors due to its open design, such as avoiding excess wire connections and keeping cable lengths within 30 feet for optimal performance.
