Description :

　　Supply weighing module | High speed A/D module | A/D module | A/D module price A/D conversion module has powerful functions and can simulate various active or passive signalssensorThe output signal is subjected to hardware processing and software standardization processing. The input signal range of the module is very wide, with a large range from+10mV to+5V, and a resolution of up to 200000 internal codes per millivolt. The measurement results can be output in a serial manner through the bus for easy operation and processing by the upper computer. This A/D conversion module can be applied to various analog sensors, AD control systems, digital instruments, etc. The interface types of this module are half duplex RS-485 interface and RS232 interface. Users can easily convert the 232 interface to other communication methods through accessories.
