Allen-Bradley 1734-IA4 Point IO Analog Input Module

The Allen-Bradley 1734-IA4 POINT I/O digital input module provides four 120 V AC digital inputs for the POINT I/O system, allowing a PLC to read field signals from line-powered devices. Each input is non-isolated and sinking, designed for direct connection to 120 VAC sources, with a total POINTBus current of up to 75 mA and a maximum power dissipation of 0.1 W for the module. The compact package measures 2.21 x 0.47 x 2.97 inches and weighs 30.9 g (1.09 oz). It uses the POINT I/O backplane to communicate with the controller, and its open-style enclosure supports straightforward installation in panel or similar environments. As part of the POINT I/O family, it integrates with Rockwell Automation controllers in POINT I/O networks for reading 120 VAC field signals, such as sensors, pushbuttons, and limit switches, in industrial control applications.
