Allen Bradley 1734-IM4 POINT I/O 220V AC Digital Input Module

Product Overview

The Allen Bradley 1734-IM4 functions as a compact, 4-point digital AC input module within the POINT I/O™ family. It monitors high-voltage discrete signals from field devices such as limit switches, push buttons, and motor starter contacts. This module excels in space-constrained cabinets where distributed I/O architecture reduces wiring costs. We offer this unit as 100% Brand New and Original, ensuring seamless integration into your existing 220V control architecture.

Technical Specifications

The 1734-IM4 provides precision monitoring for high-voltage AC circuits:

Engineering Advantages

The 1734-IM4 addresses critical electrical and spatial challenges in industrial automation:

• High-Density Footprint: The slim design minimizes DIN rail usage. This allows engineers to deploy significant I/O counts in small junction boxes or remote cabinets where traditional PLC chassis would not fit.

• Superior Noise Rejection: A 20ms hardware filter coupled with a programmable digital filter eliminates signal chatter. This prevents electrical noise common in 220V industrial environments from triggering false logic states in the controller.

• Low Heat Generation: With a maximum thermal dissipation of only 3.4 BTU/h, the 1734-IM4 prevents hotspots within dense I/O racks. This design extends the life of adjacent electronic components by maintaining a stable ambient temperature.

• Versatile Mounting Options: The module snaps directly into 1734-TB, TBS, or TOP terminal bases. This modularity allows for "wiring-before-insertion," enabling technicians to complete field wiring before installing the sensitive electronic module.

FAQs

• Does this module support 110V AC inputs?

  No. The 1734-IM4 is specifically designed for 220V AC circuits with a minimum "On-State" threshold of 159V AC. For 110V AC applications, you must use the 1734-IA series modules.

• Can I replace a module under power?

  Yes. The POINT I/O system supports Removal and Insertion Under Power (RIUP). You can swap the 1734-IM4 without interrupting the backplane communication of other modules, though you must follow standard safety protocols for the 220V field-side wiring.

• What is the condition of this unit?

  We supply only 100% Brand New original Allen Bradley stock. The unit ships in its factory box with the original UPC (612598347148) and all factory documentation included.

• Is a terminal base included with the 1734-IM4?

  No. The 1734-IM4 is the electronic module only. You must purchase a compatible terminal base, such as the 1754-TB or 1734-TBS, separately if you are performing a new installation.
