Allen-Bradley 1734-IR2 - Precision RTD Input Module

3 min read wayne Industry News

The 1734-IR2 module delivers high-accuracy temperature measurement for demanding industrial environments. This device integrates directly into a Rockwell Automation POINT I/O system. It provides two single-ended input channels for various RTD sensors. Engineers rely on this module for precise thermal process control and monitoring.

Product Procurement & Buyer Guide for the 1734-IR2

Procurement managers need a module that matches exact application specifications. The 1734-IR2 supports a wide range of RTD sensors including 100 Pt and 200 Pt types. It also accepts direct 0-600 Ω resistance signals for flexible wiring. This versatility reduces the need for multiple different module types on a system. The module offers an absolute accuracy of just 0.1% Full Scale.

Application engineers value the module's 16-bit resolution for precise data. This resolution provides 9.5 mΩ/cnt, ensuring fine granularity in measurements. The module uses a Delta Sigma conversion type for stable and reliable readings. It draws only 220 mA from the 5V DC backplane, which saves power. The compact dimensions of 56 x 12 x 75.5 mm save valuable panel space.

The module requires a compatible wiring base for installation. You must use a 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS base assembly. This design ensures a secure and reliable connection to the system backplane. The module features an open-style enclosure with no type rating. Its operating temperature range spans from -20 to 55 Celsius, which suits harsh conditions.

Expert Technical Evaluation & Performance Review

This module processes signals with exceptional speed and accuracy. The input update rate can reach as fast as 4 ms per module. This speed depends on the notch filter setting you choose for noise rejection. The module offers nine different notch filter frequencies for flexibility. This allows you to balance noise immunity against response time effectively.

Each input channel has a specific step response time matching the notch filter. For example, a 60 Hz notch gives a 50 ms step response per channel. A 480 Hz notch gives a much faster 6 ms response time. This adaptability makes the module suitable for both fast and slow processes. The continuous thermal dissipation is just 3.3 BTU per hour.

The module provides 50 Volts of continuous isolation between channels. This isolation helps prevent ground loops and protects sensitive electronics. The module outputs data in a signed integer format for easy processing. The weight is a mere 0.08 pounds, which simplifies handling during installation. The keyswitch position is 6, ensuring correct system addressing.
