Wj150 series products can be applied to RS-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. Products include signal isolation, pulse signal capture, signal conversion and RS-485 serial communication. Each serial port can be connected with 255 wj150 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, which is convenient for computer programming. Wj150 series products are intelligent monitoring and control system based on single chip microcomputer. All configuration information set by users, such as address, baud rate, data format, checksum status and so on, are stored in nonvolatile memory EEPROM. Wj150 series products are designed and manufactured according to industrial standards, with no isolation between signal input / output, strong anti-interference ability and high reliability. Operating temperature range - 45 ℃ ~ + 85 ℃. Function introduction: Wj150 remote I / O module can be used to measure 1 channel encoder signal, or set as 2 channels of independent counter or di status measurement. 1. Signal input One channel encoder signal input or two independent counters can be connected to dry contact and wet contact, and the input type can be set by command. 2. Communication protocol
