Product Summary
The 1734-IT2I is a high-precision analog temperature input module for the POINT I/O system. This device processes two differential thermocouple inputs with 15-bit resolution. It offers isolated channels to ensure signal integrity. Engineers rely on this module for accurate data in harsh environments. Its compact design saves valuable panel space.
Product Procurement & Buyer Guide
This section helps you select the right module. The 1734-IT2I integrates directly into a 1734-TBCJC wiring base. You do not need an external DC power supply for this unit. It draws just 175 mA from the POINTBus at 5 Volts. This low power consumption reduces system heat. It measures only 0.47 inches wide. This slim profile allows for high-density installations.
The module supports signed integer data with four temperature scales. You can choose Celsius, Fahrenheit, Kelvin, or Rankine. It also provides one custom mV scale. This flexibility matches many industrial applications. The conversion type is Delta Sigma. This method delivers stable and precise readings. The input voltage range is +/- 75 mV. The resolution sits at 2.5 µV/cnt.
Alarm functions protect your process. The module detects under-range and over-range conditions. It also identifies cold junction compensation (CJC) open-wire faults. Level alarms (low-low, low, high, high-high) trigger on critical values. These features reduce downtime and prevent equipment damage. The key switch position is set to 6 for configuration.
For procurement teams, this module simplifies your BOM. It shares the same form factor as other POINT I/O blocks. Its open-style enclosure allows for easy access. The operating temperature range is -20 to 55 degrees Celsius. Storage temperature extends from -4 to 85 degrees Celsius. This wide range suits many factory floor conditions.
Deep-Dive Technical FAQ
What thermocouple types work with this module?
The module accepts various thermocouple signals. It processes differential inputs with individual isolation. The 15-bit resolution provides high accuracy for small mV changes.
How does the module communicate with the controller?
It produces eight bytes of scanner data (scanner Rx). It also sends fault status data. This data transfer does not consume I/O data (scanner Tx). Status indicators show network and module health. LEDs also display input 0 and input 1 status.
What is the input impedance value?
The impedance is 100 kiloohms. The resistance measures 1 megaohm. These values ensure minimal signal loading on the thermocouple. This maintains measurement integrity over long cable runs.
Can I use this module in high-vibration environments?
Yes, it handles 5 g of operating vibration at 10 to 500 Hertz. It withstands 30 g of operating shock. Non-operating shock tolerance is 50 g. This ruggedness fits demanding industrial machinery.
What are the isolation specifications?
The continuous isolation voltage is 50 Volts. This protects the module from ground loops. It enhances safety for operators and connected equipment.
