The Allen-Bradley 1756-IB16D ControlLogix module is a sophisticated DC digital I/O solution, featuring 16 diagnostic inputs that are grouped into sets of four. It integrates seamlessly with the 1756 ControlLogix chassis and requires a 1756-TBNH or 1756-TBSH removable terminal block for optimal performance. This module provides valuable diagnostic data including no load detection and timestamping for module faults, enhancing system monitoring capabilities, while operating within a voltage range of 10 to 30V DC with a nominal input of 24V DC. It offers a rapid input delay time, user-selectable filtering for signal accuracy, and ensures efficient energy consumption with a total backplane power of 0.84W and a maximum thermal dissipation of 19.78 BTU/hour.
