Encoder pulse counter, angular speed displacement measurement, Modbus RTU module WJ66

product description:

WJ66 product implements signal acquisition between sensors and hosts to decode encoder signals and device control. WJ66 series can be applied to the RS-232/485 bus industrial automation control system, automated machine tool, industrial robot, three-coordinate positioning system, displacement measurement, stroke measurement, angular measurement, speed measurement, etc.

Products include signal isolation, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can be connected up to 255 WJ66 series modules, the communication mode uses the ASCII code communication protocol or the Modbus RTU communication protocol, the baud rate can be set by the code setting, can be hung on the same RS-485 bus with other manufacturers, easy to computers Program

The WJ66 series is based on the intelligent monitoring and control system of single chip microcomputer. All user settings, baud rates, data formats, checksum, and other configuration information stored in non-volatile memory EEPROM.

WJ66 series products are not isolated from industrial standards, manufacturing, signal input / output, strong anti-interference ability, high reliability. Working temperature range - 45 ° C ~ + 85 ° C.
