4-channel grating ruler magnetic grating ruler encoder 5MHz high-speed differential signal to RS485/232/WiFi module WJ167

Product overview:

WJ167 product realizes the signal acquisition between the sensor and the host, which is used to decode the signal of the magnetic grating encoder of the grating ruler. WJ167 series products can be used in RS-232/485 bus industrial automation control system, automatic machine tools, industrial robots, three coordinate positioning system, displacement measurement, stroke measurement, angle measurement, speed measurement, flow measurement, product counting, etc.

The products include signal isolation, pulse signal capture, signal conversion and RS-485 serial communication. Each serial port can connect 255 WJ167 series modules at most. The communication mode adopts ASCII code communication protocol or MODBUS RTU communication protocol. The baud rate can be set by code and can be hung on the same RS-485 bus with the control modules of other manufacturers to facilitate computer programming.

WJ167 series products are intelligent monitoring and control systems based on single-chip microcomputer. All user set configuration information such as address, baud rate, data format, parity check, etc. are stored in non-volatile memory EEPROM.

WJ167 series products are designed and manufactured according to industrial standards, with no isolation between signal input/output, strong anti-interference capability and high reliability. Operating temperature range - 45 ℃~+85 ℃.
