Product Details
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.

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.

Tech & Buying Guide
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
Mastering Modern Industrial Joystick Controls in Heavy Automation
Industrial joysticks play a pivotal role in human-machine interaction across heavy material handling and mobile hydraulics. These tactile controllers translate complex operator movements into precise electrical signals for PLCs, motion controllers, and DCS networks. Consequently, selecting and installing the right joystick architecture ensures operator safety, reduces fatigue, and optimizes equipment performance.
