Allen Bradley 1794-IB16 Flex I/O 16-Point 24VDC Sink Input Module (Lot of 2)

The Allen Bradley 1794-IB16 is a robust Flex I/O module designed for industrial automation systems, providing 16 sink input points compatible with 24V DC signals. This module is part of the Flex I/O family, which offers modular, distributed I/O solutions for PLC systems like Allen Bradley's ControlLogix or SLC 500. It excels in applications requiring reliable digital input monitoring, such as manufacturing lines, process control, and machinery automation. Key features include high-density inputs in a compact form factor, diagnostic LEDs for status indication, and compatibility with various baseplates for flexible installation. Advantages over similar products include seamless integration with Rockwell Automation ecosystems, reduced wiring complexity, and enhanced noise immunity for harsh industrial environments. Drawbacks may include higher cost compared to generic I/O modules and dependency on proprietary systems. Based on attached images, these units appear used but in good condition, with intact labels showing part number 1794-IB16/A, manufacturing date 10/94, and no visible damage.
