III. Functional Characteristics

Compatibility with multiple signal types: It supports various common current signal types, including 0 - 20mA, 4 - 20mA, ±20mA, and 0 - 1mA. It can flexibly adapt to various analog output sensors and transmitters, such as pressure transmitters, temperature sensors, flow sensors, etc. This greatly enhances the module's versatility in different application scenarios and reduces the trouble of equipment selection caused by mismatched signal types.

High - resolution collection: It has 16 - bit high - resolution A/D conversion capability, which can perform extremely accurate digital conversion of input analog signals, effectively reducing errors in the signal conversion process. It provides high - precision data for the system, meeting the application requirements of industries with strict requirements on signal accuracy such as precision manufacturing and pharmaceutical production, and ensuring precise control of the production process and stability of product quality.

Flexible channel configuration: The 16 input channels can be flexibly set according to actual needs. They can be used as 16 single - ended input channels or combined into 8 differential input channels. This flexible configuration method can adapt to different signal measurement needs. For example, in occasions where small signals are measured or stronger anti - interference capability is required, the differential input mode can effectively suppress common - mode interference and improve the accuracy and reliability of signal collection.

Programmable digital filtering: It has a built - in low - pass digital filter, and the filter frequency can be programmed. It provides multiple optional frequencies such as 6Hz, 10Hz, 20Hz, 40Hz, 60Hz, 80Hz, 100Hz, and 250Hz. Users can select the appropriate filtering frequency according to the characteristics and interference of on - site signals, effectively filtering out high - frequency noise and interference in the signals, making the collected data more stable and reliable, and ensuring that the system can work normally in complex electromagnetic environments.

Fast data conversion: It adopts Sigma - Delta conversion technology and has a fast conversion rate. It can quickly respond to changes in input signals, timely convert analog quantities into digital quantities and transmit them to the PLC, meeting the real - time requirements of industrial control systems. In the dynamically changing production process, it ensures that the system can respond quickly to achieve precise control.

Reliable electrical isolation: It has an isolation capability of 500V AC, which can last for 1 second. It effectively isolates the input signal from the backplane circuit, preventing electrical interference from being transmitted from the input side to other parts of the system, protecting the system from electrical shocks and interference, improving the stability and reliability of the system, and ensuring that the module can run stably in the complex electrical environment of industrial sites, guaranteeing the accuracy and integrity of data collection.
