【英文介绍】

The 140ATI03000 module is built in a standard format, making it compatible with a variety of systems and Settings. It is equipped with a unipolar point low-pass filter that provides a 20 dB cutoff at 3 Hz, and a notch filter that provides a 60 dB cutoff at 3/50 Hz. These filters help eliminate unnecessary noise and interference in the input signal, ensuring accurate and reliable data acquisition.

input

The module has eight analog input channels to flexibly measure and monitor a variety of thermocouple inputs. It supports different thermocouple types and their corresponding temperature ranges. These include thermocouple S (-50 to 1665°C), thermocouple R (-50 to 1665°C), thermocouple T (-270 to 400°C), thermocouple K (-270 to 1370°C), thermocouple E (-270 to 1000°C), and thermocouple J (-210 to 760°C). This wide temperature range capability allows the module to be used in a variety of industrial environments.

The module provides high-resolution analog inputs with a resolution of 16 bits, ensuring accurate measurement and control. Its input impedance is greater than 1 MOhm, enabling accurate signal capture without compromising the integrity of the measured data.

property

In terms of accuracy, the 140ATI03000 module shows impressive performance. It has an absolute accuracy error, which varies depending on the type of thermocouple used. For thermocouples S and R, the error is within 0.1% of +/ -4 °C plus the reading. For thermocouples T, K, J and E, the error is within 0.1% of +/ -2 °C plus the reading. The module also has excellent linearity, with an error of 1 °C or 0.1 °C (depending on the temperature range).

trait

Temperature changes can affect measurement accuracy, but the 140ATI03000 module compensates for this with its accuracy drift function. It has a maximum low-level voltage drift of 0.15 μV/°C plus 0.0015% of the reading /°C, thus minimizing the impact of temperature changes on measurement accuracy.

The module provides strong common-mode rejection, exceeding 60 dB at 120/50 Hz. This high rejection level helps eliminate common mode noise and interference, ensuring a clean and accurate signal.

secure

Security is an important aspect of industrial applications, and the 140ATI03000 module integrates comprehensive isolation capabilities. It provides isolation between the channel and the bus with a withstand voltage of 2500 V DC for 60 seconds and 1780 V AC for 60 seconds. In addition, it provides isolation between 220 V AC and 300 V DC rated channels, thus enhancing safety and preventing potential electrical hazards.

communication

The module has the function of sending out local signals through leds, in which eight red leds indicate that the channel is faulty and eight green leds indicate that the corresponding channel is open. In addition, there are two leds: a red LED indicating an external fault and a green LED indicating active bus communication.

The module requires a bus current of 280 mA and a power consumption of 1.5 W, allowing efficient operation while minimizing power consumption.

The Schneider Electric part number 140ATI03000 is CE certified, indicating compliance with European safety standards.
