Product overview:

Wj150 product realizes signal acquisition between sensor and host, which is used to decode encoder signal. 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

Communication interface: one standard RS-485 communication interface.

Communication protocol: two protocols are supported: character protocol defined by command set and Modbus RTU communication protocol. The module automatically identifies the communication protocol and can realize network communication with various brands of PLC, RTU or computer monitoring system.

Data format: 10 bits. 1 start bit, 8 data bits, 1 stop bit. No verification.

Communication address (0 ~ 255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; The longest distance of the communication network can reach 1200 meters, which is connected through twisted pair shielded cables.

High anti-interference design of communication interface, ± 15kV ESD protection, and communication response time is less than 100ms.

3. Anti interference

Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively suppress various surge pulses, protect the module, internal digital filtering, and well suppress the power frequency interference from the power grid.
