The Allen-Bradley 1756-IA8D ControlLogix Digital I/O module is expertly designed for seamless integration within the 1756 ControlLogix chassis, operating specifically with the 1756-TNBH or 1756-TBSH removable terminal blocks. This module features eight diagnostic inputs divided into four points per group and boasts advanced Field Power Loss detection, which efficiently communicates point-specific faults to the controller. With a nominal input voltage of 120 Volts AC and configurable functions such as Change of State, Input Filter Times, and Diagnostic Latching, this module ensures precise control and monitoring. It operates effectively within a voltage range of 79 to 132 V AC, with a backplane current draw at 100 mA for 5.1 V DC and 3 mA for 24 V DC, offering optimal power efficiency and reliable performance in industrial applications.
