Product Overview:

The WJ159 product achieves signal acquisition between sensors and the host, used to decode grating and magnetic grating signals. The WJ159 series products can be applied in RS-485 bus industrial automation control systems, automated machine tools, industrial robots, three coordinate positioning systems, displacement measurement, stroke measurement, angle measurement, rotational speed measurement, product meter measurement, and so on.

The products include signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect 255 WJ159 series modules at most. The communication mode adopts ASCII code communication protocol or MODBUS RTU communication protocol. The Baud 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 The WJ159 series products are intelligent monitoring and control systems based on microcontrollers. All user set configuration information such as address, baud rate, data format, checksum status, etc. are stored in non-volatilememory EEPROM. The WJ159 series products are designed and manufactured according to industrial standards, with no isolationbetween signal inputs/outputs, strong anti-interference ability, and high reliability. The working temperature rangeis-45 ℃ to+85 ℃.

Function Introduction:

The WJ159 remote I/O module can be used to measure 1 channel of 5V differential grating encoder signal. 1、 Signal input 1-channel 5V differential grating ruler magnetic grating ruler encoder signal input. 2、 Communication Protocol Communication interface: 1 standard RS-485 communication interface. Communication Protocol: Supports two protocols, the character protocol defined by the command set andtheMODBUS RTU communication protocol. The module automatically recognizes communicationprotocols and can achieve network communication with various brands of PLCs, RTUs, or computermonitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. No verification. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) canbeset;The communication network can reach a maximum distance of 1200 meters and is connectedthroughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3、 anti-interference Checksums can be set as needed. There is a transient suppression diode inside the module, which caneffectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppresspowerfrequency interference from the power grid.
