Product Overview:

The WJ166 product realizes signal acquisition between sensors and hosts, used to decode encoder signals. The WJ166 series products can be applied to RS-232/485

And WiFi bus industrial automation control system, automated machine tools, industrial robots, three coordinate positioning system, displacement measurement, stroke measurement, angle measurement

Measurement of quantity, rotational speed, flow rate, product counting, and more.

The product includes signal isolation, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ166 series modules,

The communication method adopts ASCII code communication protocol or MODBUSRTU communication protocol, and the baud rate can be set by code, which can be hung with control modules from other manufacturers

On the same RS-485 bus, it is convenient for computer programming.
