<\/p>\n

This listing is for a used Allen-Bradley Point I\/O 4 Point Digital Input Module.<\/font><\/span><\/p>\n

It works perfectly.<\/font><\/span><\/p>\n

Part Number: 1734-IA4 Series C<\/p>\n

<\/span><\/font><\/font><\/p>\n

The Allen-Bradley 1734-IA4 is a discrete digital AC input module in the 1734 POINT I\/O family, manufactured by Rockwell Automation. It is compatible with any POINT I\/O communication adapter, making it suitable for distributed I\/O architectures across ControlLogix, CompactLogix, FlexLogix, and other Logix-based platforms. Refer to manufacturer documentation to confirm compatibility with your specific application.<\/font><\/p>\n


<\/font><\/p>\n

This module provides Four (4) non-isolated, sinking input channels rated for 120V AC signals, with an input voltage range of 85\u2013132V AC at 47\u201363 Hz nominal. The minimum ON-state voltage is 65V AC and the maximum is 132V AC, with a nominal input current of 4 mA and input impedance of 10.6 kilohms. The module draws 75 mA from the POINT Bus at 5V DC and has a power dissipation of 0.50 W at 132V AC.<\/font><\/p>\n


<\/font><\/p>\n

The 1734-IA4 mounts to a dedicated terminal base and is not a standalone unit \u2014 compatible wiring base assemblies include the 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS. The module key switch is set to position Eight (8), and the module supports both horizontal and vertical DIN rail mounting orientations.<\/font><\/p>\n
