The Allen Bradley 1734-IA2 operates as a digital AC input module within the Point I/O 1734 series. Designed to handle 120 Volt AC, this module features two separate input channels that are not isolated. Each of these channels belongs to a single input grouping, allowing for streamlined connections within the control system. The nominal input voltage required for operation is 120 Volt AC, with an operational voltage range extending from 85 to 132 Volt AC.

This module supports a minimum on-state voltage of 65 Volt AC and caps the maximum off-state voltage at 43 Volt AC. The nominal on-state current usage is specified at 7.5 mA for the 120 Volt AC input, while off-state current can peak at 2.7 mA when the voltage drops to 43 Volt AC. With an input impedance of 10.6 kiloohms, the 1734-IA2 module provides stable performance under varying loads.

The isolation rating offered by this module is a continuous 240 Volts from the field to the system, ensuring that the connected equipment can operate safely. On the power side, the module draws 75 mA from the POINTBus at a DC voltage of 5 Volts. Power dissipation remains low at 0.35 Watts while running at the upper voltage limit of 132 Volt AC, affirming its efficiency in diverse applications.
