Description

The Allen-Bradley 1791-16B0 is a 16 Input DC Block I/O Module designed for distributed input monitoring through Allen-Bradley Remote I/O (RIO) networks. It provides 16 inputs arranged in two groups of eight, supports standard 24 VDC field signals, and offers selectable fast or slow input filtering for different application requirements. With multiple RIO communication rates, electrical isolation, built-in protection, and comprehensive status indication, the module enables reliable acquisition of signals from sensors, switches, pushbuttons, limit switches, and other discrete field devices. It is well suited for machinery, manufacturing lines, material handling, and legacy Allen-Bradley PLC and SLC-based automation systems.

Advantages

Compared with conventional distributed DC input modules, the Allen-Bradley 1791-16B0 combines flexible input filtering, direct Remote I/O connectivity, reliable electrical isolation, and straightforward integration with legacy Allen-Bradley control systems.

  • Provides 16 DC inputs in two groups of eight, allowing multiple field signals to be monitored efficiently from a single distributed I/O block.
  • Supports a 10–30 VDC input range, providing flexibility for common 24 VDC industrial sensors, switches, and other discrete devices.
  • Selectable fast and slow input filtering allows signal response to be optimized for either faster detection or improved resistance to signal disturbances.
  • Direct Remote I/O connectivity simplifies distributed installation and integration with compatible Allen-Bradley PLC architectures.
  • Supports multiple RIO communication rates, allowing the module to adapt to different existing network configurations.
  • Provides electrical isolation between the power supply, I/O groups, and logic, helping improve system protection and signal reliability.
  • Input, COMM, and STATUS indicators provide convenient visual diagnostics for commissioning, troubleshooting, and maintenance.
  • Supports integration with SLC 500 systems through the 1747-SN Series A scanner, making it a practical option for maintaining or extending established Allen-Bradley automation systems.
