1791D-16B0 Allen-Bradley CompactBlock I/O Base Block
The 1791D-16B0 is a CompactBlock I/O base block manufactured by Allen-Bradley for industrial automation and distributed control networks. This discrete input module features sixteen sinking digital input channels operating on a nominal 24 VDC power supply. Designed to communicate over the DeviceNet network protocol, it provides reliable data collection for machine-level control systems while streamlining panel space.
Input Channel Configuration
The module integrates sixteen discrete input channels configured for sinking signals at 24 VDC. These channels are organized to accommodate standard industrial sensors, ensuring efficient signal processing and high noise immunity in demanding operational environments.
Network Communication and Power
Operating via the DeviceNet communication protocol, the base block facilitates real-time data exchange with programmable logic controllers. It supports distributed topologies that reduce overall wiring complexity and cable runs across industrial automation nodes.
