The Allen-Bradley 1756-IN16 is a high-performance AC digital input module designed for integration with the 1756 ControlLogix chassis, requiring a removable terminal block, such as the 1756-TBSH or 1756-TBNH, for connection. This module features 16 inputs organized into two groups and is configurable for change-of-state detection and input filtering, with an operational voltage ranging from 10 to 30 Volts AC and a frequency range of 47 to 63 Hertz. Designed to offer robust performance, the module includes a continuous isolation voltage of 250 Volts, a minimal power consumption of 0.56 Watts, and precise current draw details of 100 milliamps at 5.1 Volts, catering to a demanding operating environment with customizable input delay times.
