Product Overview
The Allen-Bradley 1734-IR2E is a POINT I/O analog temperature input module designed for high-resolution RTD temperature measurement. This module provides two single-ended, non-isolated high-resolution RTD inputs, enabling precise temperature monitoring in demanding industrial environments. With a 16-bit input resolution and signed integer data format, the 1734-IR2E delivers accurate and reliable temperature data for process control applications. Its compact form factor and low power dissipation make it an efficient choice for distributed I/O systems.

Industry Applications
Its high-resolution RTD inputs provide accurate temperature readings critical for maintaining product quality and process efficiency. The module's compact size allows for easy integration into existing POINT I/O racks, reducing panel space and installation costs. By leveraging the 1734-IR2E, engineers can achieve tighter temperature control, leading to improved yield and reduced energy consumption.
Installation and Setup Guidance
Mount the 1734-IR2E module on a DIN rail using a compatible terminal base unit (1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS). Use 22 to 14 AWG shielded thermocouple wire for connections. Ensure the module is placed in the correct keyswitch position (6) to prevent improper insertion. No external DC power supply is required; the module draws power from the backplane. Verify that the operating environment stays within -20 to 55 degrees Celsius for reliable performance.
Maintenance and Reliability
Periodically inspect the module and wiring for signs of wear or damage. Keep the enclosure free of dust and contaminants. The module's open enclosure design requires careful attention to environmental conditions; avoid exposure to excessive moisture or corrosive gases. Regular calibration checks of the RTD inputs help maintain measurement accuracy over time.
Compatibility and Integration
It supports up to 6 bytes of fault status data and input data without consuming I/O data. The module is compatible with 1734-TB, 1734-TBS, 1734-TOP, and 1734-TOPS terminal bases, offering flexibility in wiring configurations.
Selection Guide and Purchasing Advice
When selecting the 1734-IR2E for your application, consider the number of RTD inputs needed and the required resolution.
