Product Overview:
The WJ153 product realizes signal acquisition between sensors and the host, used to decode grating and magnetic grating signals. The WJ153 series products can be applied in
RS-485 bus industrial automation control system, automated machine tools, industrial robots, three coordinate positioning system, displacement measurement, stroke measurement, angle measurement,
Speed measurement, product meter measurement, and so on.
The product includes signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ153 series modules,
The communication method adopts ASCII code communication protocol or MODBUS RTU communication protocol, and the baud rate can be set by the code, which can be hung with control modules from other manufacturers
On the same RS-485 bus, it is convenient for computer programming.
The WJ153 series products are intelligent monitoring and control systems based on microcontrollers, with all user set addresses, baud rates, data formats, checksums
The configuration information such as status is stored in the non-volatile memory EEPROM.
The WJ153 series products are designed and manufactured according to industrial standards, with no isolation between signal inputs/outputs, strong anti-interference ability, and high reliability. Working temperature
Temperature range -45 ℃ to+85 ℃.
Function Introduction:
The WJ153 remote I/O module can be used to measure 1 channel grating ruler magnetic grating ruler encoder signal.
1. Signal input
1 channel grating ruler magnetic grating ruler encoder signal input, can connect NPN and PNP signals, and set the input type through commands.
2. Communication protocol
Communication interface: 1 standard RS-485 communication interface.
Communication protocol: Supports two protocols, the character protocol defined by the command set and the MODBUS RTU communication protocol. The module automatically recognizes the communication protocol,
Can achieve network communication with multiple brands of PLC, RTU or computer monitoring systems.
Data format: 10 digits. 1-bit start bit, 8-bit data bit, 1-bit stop bit. No verification.
The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; communication
The longest distance of the network can reach 1200 meters and is connected through twisted pair shielded cables.
High anti-interference design of communication interface, ± 15KV ESD protection, communication response time less than 100mS.
3. Anti-interference
Checksum can be set as needed. There are transient suppression diodes inside the module, which can effectively suppress various surge pulses and protect the module
Word filtering can also effectively suppress power frequency interference from the power grid.
