The 1734-IR2E module delivers two high-resolution RTD inputs with 16-bit signed integer data format. It provides accurate temperature measurement with 0.1% full-scale accuracy and supports multiple temperature scales. Ideal for POINT I/O systems.
Product Procurement & Buyer Guide
The 1734-IR2E module offers two high-resolution RTD inputs. This analog temperature module uses a signed integer data format. It provides a 16-bit input resolution for precise readings. The module dissipates only 1 Watt of power. This low power consumption reduces heat in control cabinets.
Procurement engineers value its 50 Volt continuous isolation. The module operates from -20 to 55 degrees Celsius. Its compact dimensions are 2.21 x 0.47 x 2.97 inches. The weight is just 0.08 pounds. This lightweight design simplifies installation on DIN rails.
You must use 22 to 14 AWG shielded thermocouple wire. The module fits terminal bases like 1734-TB or 1734-TOP. No external DC supply is needed for operation. The keyswitch position is 6 for proper insertion.
Expert Technical Evaluation & Performance Review
The 1734-IR2E delivers excellent measurement accuracy. It achieves 0.1% full-scale accuracy at 25 degrees Celsius. The accuracy drift is only 30 ppm per degree Celsius. This stability ensures reliable temperature monitoring over time.
The module provides a common mode rejection ratio of 120 dB. It also offers a normal mode rejection ratio of 100 dB. These high rejection ratios minimize electrical noise interference. The input step response ranges from 6 to 60 milliseconds.
Built-in alarms detect over-range, under-range, and open wire conditions. Users can select from four temperature scales: Celsius, Fahrenheit, Kelvin, or Rankine. A custom mV scale is also available. This flexibility suits diverse industrial applications.
The 1734-IR2E uses a 16-bit resolution at 2.4 milliohms per count. It also achieves 0.006 degrees Celsius per count. This high resolution allows fine temperature differentiation. The module produces up to 6 bytes of fault data without consuming I/O data.
Real-time status indicators show network, module, and input status. The open enclosure design allows easy access for maintenance. Its thermal dissipation is just 3.3 BTU per hour. This low heat output extends component lifespan.
