4-channel voltage acquisition module

The acquisition module has 4 channels and uses a 16 bit signal acquisition chip. The collected signal type is DC 0-10V, and it supports RS232 (later upgraded to support both RS232 and RS485), which can meet the acquisition of various sensors that output this signal. After data calibration and correction, the accuracy of the module was finally determined to be 0.1%

This module is a customized product of WAKA. The prototype was developed and data calibration was completed on January 6, 2020. The acquisition module is 4-channel and uses a 16 bit signal acquisition chip. The acquisition signal type is DC 0-10V and supports RS232 (later upgraded to support both RS232 and RS485), which can meet the acquisition of various sensors that output this signal. After data calibration correction, the accuracy of the module was finally determined to be 0.1%. The calibration data is shown in the table below.
