The Allen-Bradley 1794-IB16 is a 16-channel 24V DC digital input module designed for FLEX I/O 1794 systems in distributed automation architectures. Featuring sinking inputs and a nominal operating voltage of 24V DC, the module reliably detects field signals across a wide input range from 19.2 to 31.2V DC. Each input channel is equipped with a dedicated yellow status indicator, enabling quick visual diagnostics and reducing commissioning and maintenance time. The 1794-IB16 mounts easily on a DIN rail and supports multiple FLEX I/O terminal bases, allowing flexible wiring configurations to suit various installation requirements.
Built for industrial environments, the module operates within a temperature range of 0 to 55 °C and withstands vibration levels up to 5 g. With its compact design, high input density, and proven Rockwell Automation reliability, the 1794-IB16 is an ideal solution for monitoring sensors, switches, and control devices in modern industrial control systems.
