Allen Bradley 1734-IE2V Analog Voltage Input Module

Overview

The Allen Bradley 1734-IE2V is a dual-channel analog voltage input module designed for POINT I/O distributed architectures. It provides precise measurement of low-voltage sensor signals within compact installations, offering consistent performance in applications where cabinet space, wiring simplicity, and modularity are critical. From a system integration perspective, the module is frequently selected for remote I/O drops and mixed-signal environments requiring stable analog acquisition with minimal footprint.

Technical Specifications

Applications / Use Scenarios

• Compact distributed I/O stations in packaging, material handling, and assembly machinery

• Measurement of voltage outputs from position sensors, small transducers, and control potentiometers

• Remote acquisition nodes in Ethernet/IP or ControlNet architectures

• Retrofit panels requiring minimal expansion width

• Hybrid control systems where analog voltage measurements coexist with digital I/O on the same POINT I/O platform

Advantages / Engineering Benefits

• Minimal width footprint allows dense I/O placement in small control panels

• Stable high-resolution voltage measurement suitable for precision analog devices

• Flexible unipolar/bipolar configuration supports a variety of field sensors

• Plug-and-play integration with all POINT I/O backplanes and communication adapters

• Low power consumption ideal for distributed power-limited cabinets

• Consistent thermal stability ensures reliable readings in industrial environments

Technical FAQs

1. How many voltage input channels does the module provide?
   It provides two independent voltage input channels.

2. What voltage ranges are supported?
   The module supports both 0–10 V and ±10 V ranges.

3. Does it provide channel-to-channel isolation?
   No, the two channels share a common reference.

4. Is filtering configurable?
   Yes, software-configurable digital filtering is supported through the controller.

5. What is the resolution of the input conversion?
   The module uses a 15-bit plus sign A/D converter.

6. Can it operate in high-temperature panels?
   Yes, up to +55 °C without derating.

7. How is calibration handled?
   Factory-calibrated; field calibration is typically not required.

8. How does it receive power?
   Through the POINT I/O backplane from its base module.

9. Is the wiring shielded or unshielded?
   Both can be used; shielded wiring is recommended for noise-sensitive applications.

10. What controller families are compatible?
    CompactLogix, ControlLogix, and any system supporting POINT I/O adapters.
