140AII33000

The 140AII33000 from Schneider Electric functions as a specialized temperature input module within the I/O Modules series. This device is capable of handling up to eight analog input signals, designed specifically for accurate thermal measurement. Users can select either a measurement current of 0.5 mA or the higher 2.5 mA options, which allows for versatility in application depending on the connected sensors.

It features a source resistance limitation of less than 200 Ohm for thermocouples and maintains a high input impedance of over 10 MOhm for RTDs. With a remarkably precise linearity of 0.003% of full scale, this module ensures highly accurate temperature readings across a broad operational spectrum.

This unit dissipates a power of 2 W and requires 400 mA bus current to function efficiently. Built-in protection is provided via an internal fuse, which offers added reliability in electrical circuits. The temperature input module is resistant to electromagnetic interference, withstanding levels of 9.1 V/m. Furthermore, it can operate optimally at elevations of up to 5000 meters and is rated for high humidity conditions, capable of functioning effectively in up to 95% relative humidity without the risk of condensation. Weighing only 0.3 kg, this module is suitable for applications where space and weight considerations are critical.
