Allen Bradley 1734-IR2 POINT I/O 2-Channel RTD Input Module

Product Overview

The Allen Bradley 1734-IR2 provides high-density temperature sensing capability within the compact POINT I/O platform. This module interfaces directly with Resistance Temperature Detectors (RTDs) or resistance sensors, converting ohmic values into precise digital data for the controller. Its ultra-compact design allows for distributed I/O placement closer to the process, reducing expensive thermocouple or RTD extension wire runs. We supply this unit as 100% Brand New to guarantee the highest measurement accuracy and long-term stability in your control loop.

Technical Specifications

Engineering Advantages

• Superior Noise Rejection: The 1734-IR2 utilizes Delta-Sigma conversion technology and delivers a 120 dB rejection ratio for both common and normal modes. This effectively eliminates electrical interference from nearby VFDs and heavy motors, ensuring clean temperature data.

• High-Resolution Precision: The 16-bit resolution captures minute temperature fluctuations. This level of detail allows for tighter PID control in sensitive applications like food processing or chemical reaction monitoring.

• Space-Saving Distributed I/O: The slim POINT I/O footprint maximizes cabinet space. Engineers can mount the 1734-IR2 in small junction boxes near the point of measurement, which significantly simplifies cable management and reduces signal degradation over long distances.

• Instant Diagnostics: Integrated status indicators provide immediate feedback on module health and network connectivity. This allows maintenance teams to identify sensor faults or communication errors without opening a laptop, drastically reducing Mean Time to Repair (MTTR).

FAQs

• Which terminal base is compatible with the 1734-IR2?

  The module typically installs onto a 1734-TB or 1734-TBS wiring base. These bases allow you to replace the module (RIUP - Removal and Insertion Under Power) without disturbing the field wiring.

• Does the 1734-IR2 support 3-wire or 4-wire RTDs?

  The 1734-IR2 supports 2-wire and 3-wire RTD configurations. For high-precision requirements, the 3-wire connection compensates for lead-wire resistance, which ensures the accuracy of the temperature reading.

• Is this a brand new original component?

  Yes. We guarantee that this 1734-IR2 is 100% Brand New in its original factory packaging. It has never been installed or refurbished, ensuring it meets all original Allen Bradley performance specifications.

• How does the module handle signal scaling?

  The module outputs data in a Signed Integer format. You can easily scale these values within the Logix Designer software to represent actual temperature in Celsius, Fahrenheit, or raw Ohms depending on your application needs.
