The Schneider Electric 140ARI03000C is a high-performance RTD input module from the renowned Modicon Quantum series. This module provides eight dedicated channels for connecting resistance temperature detectors, making it ideal for multi-point temperature monitoring applications. Its sigma-delta ADC technology delivers a precise 15-bit input resolution, ensuring accurate and stable readings. Furthermore, the module offers exceptional noise rejection, which guarantees reliable performance even in electrically noisy industrial environments. This combination of channel density, precision, and robustness makes the 140ARI03000C an excellent choice for process control and monitoring systems.
The 140ARI03000C supports up to eight RTD input channels, allowing for efficient temperature monitoring across multiple points. The sigma-delta conversion method provides an input resolution of 15 bits, which translates to high measurement granularity and accuracy. Internal recalibration maintains measurement precision over time, reducing the need for manual adjustments. Additionally, the module handles common RTD types, including Pt100 and Ni100, providing flexibility for various sensor configurations.
This RTD module excels in environments with significant electrical interference. It offers a common mode rejection of 120 dB, which effectively eliminates noise present on both input lines. Similarly, its differential mode rejection of 60 dB suppresses normal-mode noise that could corrupt the measurement signal. Consequently, the 140ARI03000C delivers stable and accurate temperature readings, even when installed near variable frequency drives or other noise-generating equipment.
The Schneider Electric 140ARI03000C operates within an ambient temperature range of 0 to 60 °C, making it suitable for typical control room environments. For storage, it withstands temperatures from -40 to 85 °C, ensuring resilience during transportation and seasonal shutdowns. The module operates at altitudes from 0 to 2000 meters above sea level, accommodating installations at various geographic locations. Furthermore, its IP20 protection class makes it suitable for indoor installation within protected control cabinets.
Weighing just 209 grams, this module features a compact design that minimizes mechanical load on the backplane. Its lightweight construction allows for easy handling during installation and maintenance. The module's dimensions are consistent with other Modicon Quantum I/O modules, ensuring uniform mounting and efficient use of rack space.
