Description

The Allen-Bradley 1794-IB32 FLEX I/O digital input module is designed for distributed 24V DC discrete input applications in FLEX I/O systems. It provides 32 current-sinking inputs for machine control, panel integration, and remote I/O architectures where compact high-density digital input capacity is required.
