Allen-Bradley 1794-IB32 Flex IO Digital Input Module

The Allen-Bradley 1794-IB32 FLEX I/O digital input module provides 32 sinking 24V DC inputs for distributed control systems, enabling high-density DC input monitoring within modular automation architectures. It collects discrete signals from sensors, limit switches, proximity devices, and pushbuttons, and relays status data to Logix-based controllers through FLEX I/O network adapters, making it well suited for machine-mounted I/O stations on automated production lines. Key specifications include 24V DC input, an input voltage range of 10–31.2V DC, channel-to-backplane isolation, DIN-rail mounting (requires FLEX I/O terminal base), and an operating temperature range of 0 to 55°C, with current draw module dependent. Common replacements include Allen-Bradley 1794-IB16, 1794-OB32, and 1734-IB8.
