Allen-Bradley 1794-IA16 Flex Digital Input Module

The Allen-Bradley 1794-IA16 Flex Digital Input Module provides 16 sourcing 120V AC digital inputs for FLEX I/O networks, enabling reliable sensing of field devices to ControlLogix, CompactLogix, and other Logix platforms via FLEX I/O adapters. Key specifications include 16 AC inputs, 120V AC nominal with an input range of 79–132V AC (47–63 Hz), and channel-to-backplane isolation for safe, modular expansion. Designed for DIN-rail mounting with a FLEX I/O terminal base, it is commonly installed in machine-mounted I/O panels, production lines, material handling systems, and process control applications where dependable 120V AC signaling from pushbuttons, selector switches, limit switches, and relay contacts is required. Common replacements for expansion or retrofit include Allen-Bradley 1794-IB16 and 1794-IA8.
