• Operating Temperature Range: Has an extremely wide operating temperature adaptation range, and can operate stably in extreme ambient temperatures of -40°C to 75°C. Whether it is a cold polar industrial facility or a hot desert chemical plant, as long as the ambient temperature is within this range, CC-TAIX01 can maintain a normal working state, continuously and accurately collect and transmit signals, and strongly guarantee the continuity of industrial production under various harsh climate conditions.

• Humidity Range: Can work reliably in an environment with a relative humidity of 5% - 95% (non-condensing). The electronic components inside the module have undergone special moisture-proof treatment, which can effectively resist the erosion of humid air, prevent short circuits, oxidation and other faults caused by humidity problems, ensure long-term stable operation in humid coastal factories, underground mines and other environments, extend the service life of the equipment, and reduce maintenance costs.

Vibration and Shock Resistance

• Vibration: Can withstand vibration with 5g peak-to-peak value and a frequency range of 10 to 2000Hz. In the vibration environment commonly caused by the operation of large mechanical equipment, vehicle transportation, etc. in industrial fields, the internal circuits and components of the module will not loosen or be damaged due to vibration, ensuring the stability and reliability of signal collection and transmission.

• Shock: Can resist shock of 50g with a duration of 11ms. Even in case of accidental mechanical shock, such as equipment collision and falling, the module can maintain normal working state to the greatest extent, reduce data loss or equipment failure caused by shock, and ensure the stable operation of the industrial automation system.

III. Functional Features

(I) High-Precision Analog Signal Acquisition

• Multi-Type Signal Compatible Acquisition: CC-TCNT01 can access multiple types of analog input signals at the same time, such as thermocouple, RTD, voltage, current signals, etc. This feature enables it to flexibly adapt to complex and diverse sensors in industrial fields. Whether it is the measurement of process parameters such as temperature, pressure, flow, and liquid level, or the monitoring of equipment operation status, signals can be accurately collected to the module through corresponding sensors, providing comprehensive and accurate data support for the control system.

• High-Resolution and Precision Measurement: The combination of 12-bit resolution and ±0.25% full-scale accuracy makes the module's measurement of analog signals extremely fine and accurate. Taking temperature measurement as an example, when the thermocouple measures the range of -200 to 1800°C, it can accurately distinguish temperature changes, providing reliable data basis for industrial processes that require high precision in temperature control, such as chemical reactor temperature control and food baking temperature monitoring, effectively avoiding product quality problems or production accidents caused by temperature control deviations.

(II) Strong Signal Isolation and Anti-Interference Ability

• Electrical Isolation Protection: The high isolation voltage design of 2500V builds a solid electrical barrier between the module input and the internal circuit. This can not only effectively block the damage of on-site strong electrical signals and surge currents to the module, but also prevent signal crosstalk between different input channels, ensure the independence and accuracy of signals collected by each channel, improve the working reliability of the module in complex electromagnetic environments, and ensure the stable operation of the industrial automation system.

• Anti-Interference Circuit Design: The module integrates advanced anti-interference circuits, which can effectively suppress various electromagnetic interferences from industrial fields, such as high-frequency interference generated by frequency converters and motor start-stop, and power frequency interference from transmission lines. Through filtering, shielding and other technical means, it ensures that the collected analog signals are pure and stable, avoids measurement errors and data fluctuations caused by interference signals, and provides reliable original data for the control system.

(IV) Reliable Diagnosis and Maintenance Functions

• Real-Time Status Monitoring: The module has a complete self-diagnosis function, which can monitor its own working status in real time, including power status, communication status, signal status of each input channel, etc. Once an abnormality is found, such as channel failure, communication interruption, power supply abnormality, etc., it can immediately generate detailed fault information and upload it to the control system through the communication interface. At the same time, the LED indicators on the module will intuitively feedback the fault type with a specific flashing mode, facilitating maintenance personnel to quickly locate and troubleshoot problems, shorten fault handling time, and reduce losses caused by production interruption.

• Fault Early Warning and Prevention: By continuously analyzing the module's operation data, CC-TCNT01 can predict potential fault risks in advance. For example, when it is detected that the signal noise of a certain channel is gradually increasing and the measured value shows an abnormal fluctuation trend, the system can send an early warning signal, prompting maintenance personnel to check the relevant sensors or lines in time, take maintenance measures in advance, avoid equipment shutdown caused by further deterioration of the fault, and improve the reliability and availability of the industrial automation system.
