The Schneider Electric 140ATI03000 is a high-performance analog input module designed for the Modicon Quantum automation platform. It accepts up to eight thermocouple inputs, covering types J, E, K, T, R, and S. This module delivers 16-bit resolution and includes both notch and low-pass filtering for stable readings. Consequently, it is an excellent choice for temperature monitoring in manufacturing, power generation, and process control.
Additionally, the 140ATI03000 provides internal cold junction compensation from 0 to 60 °C. This feature reduces measurement errors caused by ambient temperature changes. The module also offers strong isolation between channels and the bus, ensuring safety and signal integrity. For instance, it withstands 1780 V AC and 2500 V DC isolation tests. Therefore, you can use it in harsh electrical environments without concern.
This input module requires only 10 input words for addressing, saving PLC memory space. Its update time is 1000 ms, which is sufficient for most real-time control loops. The absolute accuracy varies by thermocouple type: ±2 °C plus 0.1% of reading for E, J, K, and T types; ±4 °C plus 0.1% for R and S types. Furthermore, the linearity error remains within 1 °C or 1 °F across all supported ranges.
The 140ATI03000 also features excellent common mode rejection (> -120 dB at 50/60 Hz). This ensures that electrical noise does not affect your temperature readings. The module’s power dissipation is only 1.5 W, and it draws 280 mA from the bus. These low power requirements make it energy-efficient for large systems.
The Schneider Electric 140ATI03000 operates reliably between 0 and 60 °C ambient temperature. Storage temperature ranges from -40 to 85 °C. Moreover, it tolerates up to 95% relative humidity without condensation. The module is certified to UL 508, CSA C22.2 No 142, and FM Class 1 Division 2. Therefore, it suits both indoor and limited hazardous area installations. Its operating altitude reaches 5000 meters, making it versatile for high-elevation sites.
Installing the 140ATI03000 is straightforward. First, ensure the PLC rack is powered off. Next, insert the module into a standard Quantum slot. Then, secure it with the retaining screws. After that, connect your thermocouple wires to the front terminals, respecting polarity. Finally, configure the input type and filter settings in your Unity Pro or Concept software. Remember to use shielded cables for the thermocouple runs to minimize noise. Additionally, keep the wiring away from high-power cables to avoid interference.
Your package includes one Schneider Electric 140ATI03000 module. The unit comes in a standard box measuring 16.5 x 31.5 x 5 cm. The total package weight is approximately 425 g. We ship worldwide via FedEx, UPS, or DHL. All shipments are fully tracked and insured. Please note that certificates and warranty are not included in the packing list.
1. Which thermocouple types does the 140ATI03000 support?
It supports J, E, K, T, R, and S types. Each channel can be independently configured for any of these types.
2. How does the module handle cold junction compensation?
The 140ATI03000 uses internal compensation from 0 to 60 °C. For best accuracy, place the module in a stable temperature environment.
3. Can I replace a faulty channel without changing the whole module?
No, the 140ATI03000 does not have field-replaceable channels. You must replace the entire module if a channel fails.
4. What is the typical update time for all 8 channels?
The update time is 1000 ms for all channels simultaneously. This is fixed and cannot be adjusted.
5. Is the 140ATI03000 compatible with older Quantum racks?
Yes, it fits all standard Modicon Quantum racks. However, confirm that your rack firmware supports this module version.
