Allen Bradley 1734-IT2I Analog thermocouple input module

FAQ

Q1. What is the main function of the 1734‑IT2I module?
It accepts thermocouple voltage signals and converts them into digital values for temperature measurement in POINT I/O systems.

Q2. How many thermocouple inputs does it provide?
It provides two isolated differential thermocouple input channels.

Q3. What type of thermocouples can it measure?
It measures thermocouple voltages within ±75 mV, which covers common thermocouple types when used with the appropriate cold‑junction compensation base.

Q4. Does the module include cold‑junction compensation?
No — it requires a separate 1734‑RTBCJC terminal base for cold‑junction compensation.

Q5. What supply voltage does it require?
It operates on 24 V DC from the POINT I/O bus.

Q6. What is the resolution of the analog inputs?
It uses a 15‑bit plus sign resolution, giving about 2.5 µV/count precision.

Q7. What is the operating temperature range?
The module is rated for −20 °C to +55 °C industrial environments.

Q8. What are the physical size and weight of this module?
The module measures approximately 56 × 12 × 75.5 mm and weighs around 41–42 g.
