Information About 1734-IT2I

The Allen-Bradley 1734-IT2I is a POINT isolated analog temperature input module. Two differential individually-isolated thermocouple inputs are available with this module. Eight bytes of scanner data (scanner Rx) and fault status data can be produced without consuming I/O data (scanner Tx). Status indicators let the users monitor the network status, module status, the status of input 0, and the status of input 1 in real time. The 1734-IT2I comes with a resolution of 15 bits at 2.5 µV/cnt. No external DC power supply is necessary, but the 1734-IT2I can only be installed to the 1734-TBCJC wiring base assembly. The 1734-IT2I measures 2.21 x 0.47 x 2.97 inches and it weighs 0.08 pounds or 0.036 kilograms. It has an open-style enclosure.

It has signed integer data formats with 4 temperature scales, Celsius, Fahrenheit, Kelvin, and Rankine, and 1 mV custom scale are available with the 1734-IT2I module and its conversion type is Delta Sigma. It also features alarms for conditions including under-range, over-range, cold junction compensation (CJC) open-wire detection, and level (low-low, low, high, high-high). The input voltage of the 1734-IT2I is +/- 75 mV, the voltage rating is 24 Volts DC, and the POINTbus current is 175 mA at 5 Volts DC. It has an impedance of 100 kiloohms and a resistance of 1 megaohm. It has a maximum power dissipation of 1 Watt and a maximum thermal dissipation of 3.3 BTU/hour. The continuous isolation voltage is 50 Volts, the operating temperature is -20 to 55 degrees Celsius, and the storage temperature is -4 to 85 degrees Celsius. The 1734-IT2I has a non-condensing relative humidity of 5 to 95% and an operating vibration of 5 g at 10 to 500 Hertz. The operating shock is 30 g and the non-operating shock is 50 g.

Frequently Asked Questions about 1734-IT2I
Question: What is the primary function of the 1734-IT2I module?
Date Update:03/06/2025
Answer:

The Allen-Bradley 1734-IT2I is a POINT I/O module designed to interface with thermocouple sensors. It provides two isolated differential input channels for accurate temperature measurements. The module supports various thermocouple types, including B, C, E, J, K, N, R, S, and T, as well as millivolt inputs ranging from -75 mV to +75 mV. This versatility makes it suitable for a wide range of industrial temperature monitoring applications.

Question: What are the key technical specifications of the 1734-IT2I module?
Date Update:03/06/2025
Answer:
  • Input Channels: 2 isolated differential inputs
  • Input Range: ±75 mV DC
  • Resolution: 15 bits (approximately 2.5 µV/count)
  • Input Impedance: 100 kΩ
  • Power Supply: 24V DC
  • POINTBus Current: 175 mA at 5V DC
  • Isolation Voltage: 50V continuous (basic insulation), type tested at 1600V AC for 60 seconds
  • Operating Temperature: -20°C to +55°C (-4°F to +131°F)
  • Storage Temperature: -40°C to +85°C (-40°F to +185°F)
  • Relative Humidity: 5% to 95% non-condensing
  • Dimensions (H x W x D): 56 x 12 x 75.5 mm (2.21 x 0.47 x 2.97 in.)
  • Weight: Approximately 0.036 kg (0.08 lb)
  • Mounting: DIN rail
  • Enclosure Type: Open-style
Question: How does the 1734-IT2I module handle data communication and diagnostics?
Date Update:03/06/2025
Answer:

The 1734-IT2I module produces 8 bytes of input data, which includes temperature readings and status information for each channel. It does not consume I/O data. The status bytes provide diagnostic information such as overrange, underrange, high-high alarm, low-low alarm, high alarm, low alarm, calibration mode, and channel fault status. These diagnostics help in monitoring the health and performance of the thermocouple inputs.

Question: What wiring and installation considerations are there for the 1734-IT2I?
Date Update:03/06/2025
Answer:

The 1734-IT2I module requires the use of the 1734-TBCJC wiring base assembly for proper installation. When wiring thermocouples, it's important to use shielded thermocouple extension wire of the same type as the sensor to maintain measurement accuracy. The module supports both two-wire and three-wire RTD connections, and proper wiring practices should be followed to ensure reliable operation.

Question: What safety and environmental standards does the 1734-IT2I comply with?
Date Update:03/06/2025
Answer:

The 1734-IT2I module is designed to operate in industrial environments and complies with various safety and environmental standards. It has an open-style enclosure, suitable for installation within a protective cabinet. The module is tested for a continuous isolation voltage of 50V and can withstand a type test of 1600V AC for 60 seconds. It operates reliably within a temperature range of -20°C to +55°C and can be stored in temperatures ranging from -40°C to +85°C. The module also meets relative humidity requirements of 5% to 95% non-condensing.
