Type: Digital Input Module
Price: 66.00

Product Overview

The Allen Bradley 1734-IV8 functions as a high-density digital input module within the POINT I/O™ family. This module provides eight sourcing-type input points, allowing for seamless integration of 24V DC field devices such as proximity sensors, limit switches, and photoelectric eyes. Its ultra-compact, modular design minimizes panel space while providing granular I/O expansion for distributed control architectures. We supply this unit in 100% Brand New and Original condition, ensuring maximum signal integrity and backplane compatibility for your Logix-based control systems.

Engineering Advantages

The 1734-IV8 addresses critical spatial and diagnostic challenges in modern automation:

High-Density Footprint: The "Point" architecture allows for 8 discrete inputs in a housing less than 13mm wide. This compact scale enables significant I/O expansion in small junction boxes or crowded control cabinets where traditional rack-based I/O is physically impossible.

Sourcing Input Configuration: This module utilizes a sourcing (PNP-compatible) input structure. It provides a common ground for the field devices, simplifying the wiring of 3-wire PNP sensors and reducing the need for additional terminal blocks.

Real-Time Visual Diagnostics: Integrated LED indicators provide instantaneous feedback for each of the 8 points. Technicians can identify faulty field devices or broken wires at a glance without utilizing a programming terminal, significantly reducing Mean Time to Repair (MTTR).

Flexible Mounting and Assembly: The module snaps onto a 1734-TB or 1734-TBS terminal base. This "Removal and Insertion Under Power" (RIUP) capability allows for module replacement without disturbing the field wiring or interrupting the power to other modules on the same DIN rail.

FAQs

What is the difference between the 1734-IB8 and the 1734-IV8?

The 1734-IB8 is a sinking input module (requires sourcing sensors), whereas the 1734-IV8 is a sourcing input module (requires sinking sensors). Always verify the output type of your field devices (PNP vs. NPN) before selecting the module to ensure electrical compatibility.

Which terminal base does the 1734-IV8 require?

This module installs onto a 1734-TB, 1734-TBS, or 1734-TOP terminal base. The base provides the connection points for field wiring and secures the module to the DIN rail.

Can I replace this module while the system is powered?

Yes. The POINT I/O system supports RIUP (Removal and Insertion Under Power). You can remove and replace the 1734-IV8 module while the rest of the I/O system remains operational, provided you follow standard industrial safety procedures.

Is this a genuine, factory-sealed Allen Bradley unit?

We guarantee the unit is 100% Brand New and Original. Every 1734-IV8 ships in its original factory packaging with the authentic UPC (612598309832) and Rockwell Automation quality inspection seals intact.
