Precision Signal Processing
The 1734-IT2I uses a Delta Sigma conversion type for accurate signal measurement. It provides a resolution of 15 bits at 2.5 µV per count. This module supports signed integer data formats for flexibility. You can choose from four temperature scales including Celsius, Fahrenheit, Kelvin, and Rankine. A custom mV scale is also available for specialized applications.
Robust Input Isolation
This module features two differential individually-isolated thermocouple inputs. The continuous isolation voltage is 50 Volts for reliable operation. Each input channel maintains its own isolation barrier. This design prevents ground loop interference between channels. Your system gains enhanced noise immunity and measurement accuracy.
Comprehensive Diagnostic Capabilities
The module includes status indicators for network, module, and input status. It produces eight bytes of scanner data for fault status. Alarms cover under-range, over-range, and cold junction compensation errors. Open-wire detection and level alarms (low-low, low, high, high-high) are standard. These features enable proactive maintenance and reduce downtime.
Environmental Durability
The 1734-IT2I operates reliably in temperatures from -20 to 55 degrees Celsius. It withstands non-condensing relative humidity from 5 to 95 percent. The module handles operating vibration of 5 g at 10 to 500 Hertz. It survives operating shock of 30 g and non-operating shock of 50 g. This rugged design suits harsh industrial environments.
Power Efficiency and Physical Design
The module draws only 175 milliamps from the POINTBus at 5 Volts DC. Maximum power dissipation is just 1 Watt with thermal dissipation of 3.3 BTU per hour. Its compact size measures 2.21 x 0.47 x 2.97 inches. The unit weighs only 0.08 pounds or 0.036 kilograms. This lightweight design saves valuable cabinet space.
Installation Requirements
The 1734-IT2I requires the 1734-TBCJC wiring base assembly for installation. No external DC power supply is necessary for operation. The key switch position is set to position 6. Input impedance is 100 kiloohms with a resistance of 1 megaohm. These specifications ensure proper signal conditioning for your thermocouples.
