Allen-Bradley 1734-IR2E POINT I/O Analog Temperature Input Module

Product Overview

When precise temperature monitoring is critical in industrial processes, the Allen-Bradley 1734-IR2E delivers reliable performance. This POINT I/O Analog Temperature Input Module features 2 high-resolution RTD inputs with 16-bit resolution, ensuring accurate data acquisition for demanding applications. Part of the Rockwell Automation POINT I/O family, the 1734-IR2E integrates seamlessly into distributed control systems.

Technical Specifications

The 1734-IR2E offers a data format of Signed Integer and an input resolution of 16 bits. It provides an isolation voltage of 50 Volts continuous and dissipates only 1 Watt of power, with thermal dissipation of 3.3 BTU/hour. The module operates in temperatures from -20 to 55 degrees Celsius and measures 2.21 x 0.47 x 2.97 inches (H x W x D), weighing 0.08 pounds (0.036 kilograms). It has an open enclosure and a keyswitch position of 6.

Industry Applications

This module excels in temperature monitoring for manufacturing, chemical processing, and HVAC systems. Its 2 RTD inputs allow direct connection to platinum RTD sensors, providing linearized temperature readings. The high common mode rejection ratio (120 dB) and normal mode rejection ratio (100 dB) ensure stable readings even in electrically noisy environments, reducing false alarms and downtime.

Installation & Setup Guidance

Mount the 1734-IR2E on a DIN rail using a compatible terminal base unit such as the 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS. Use 22 to 14 AWG shielded thermocouple wire for connections. No external DC power supply is needed—the module draws power from the backplane. Set the keyswitch to position 6 to prevent incorrect module insertion.

Maintenance & Reliability

With a power dissipation of just 1 Watt, the 1734-IR2E generates minimal heat, enhancing long-term reliability in control cabinets. The open enclosure design allows for natural convection cooling. Periodic inspection of wiring and connector integrity is recommended to maintain optimal performance.

Compatibility & Integration

The 1734-IR2E integrates with Allen-Bradley POINT I/O systems and communicates via the backplane to controllers such as CompactLogix or ControlLogix. It supports up to 6 bytes of fault status data and input data without consuming I/O data, preserving system resources.
