product description:

WJ150 product implements signal acquisition between sensors and hosts to decode encoder signals. WJ150 series products can be applied to RS-485 bus industrial automation control systems, automated machine tools, industrial robots, three-coordinate positioning systems, displacement measurements, stroke measurements, angular measurements, speed measurements, flow measurements, product counts, and more.

Products include signal isolation, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can be connected up to 255 WJ150 series modules. The communication mode uses the ASCII code communication protocol or the Modbus RTU communication protocol. The baud rate can be set by the code setting, and can be hung on the same RS-485 bus with other manufacturers' control modules, which is easy to computer Program.

The WJ150 series is based on the intelligent monitoring and control system of single chip microcomputers, all user settings, baud rates, data formats, checksum and other configuration information stored in non-volatile memory EEPROM.

WJ150 series products are designed, manufactured, and signal input / output is not isolated from industrial standards, strong anti-interference ability and high reliability. Working temperature range - 45 ° C ~ + 85 ° C.

Function introduction:

The WJ150 remote I / O module can be used to measure the 1-channel encoder signal, or it can be set as a 2-way independent counter or DI status measurement.

1, signal input

1-channel encoder signal input or 2-way independent counter, connectable dry contacts, and wet points, and set the input type by command.

2, communication protocol

Communication interface: 1 standard RS-485 communication interface.

Communication Agreement: Supports two protocols, command set defined character protocols and Modbus RTU communication protocols. The module automatically identifies the communication protocol, which enables network communication with a variety of powers of PLC, RTU, or computer monitoring system.

Data format: 10 digits. 1 start position, 8-bit data bit, 1 stop bit. No check.

The communication address (0 ~ 255) and baud rate (2400, 4800, 9600, 115200 bps) can be set; the longest distance of the communication network can be 1200 meters and is connected by a twisted cable.

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

3, anti-interference

You can set the checksum as needed. There is a transient suppression diode inside the module, which can effectively suppress various inmuri pulses, protective modules, and digital filtering inside, or well inhibiting power frequency interference from the grid.
