product description:

WJ65 products implement the signal acquisition and control between the sensor and the host to detect the switching signal, or control the operation of the device. The WJ65 series products can be applied to the industrial automation control system of the RS-232/485 bus, the measurement and control of the switching signal signal, the measurement and output of high and low level signals, and industrial field signal isolation and long-term transmission.

Products include power conditioning, switching quantity collection, switching output and RS-485 serial communication. Each serial port can connect up to 255 WJ65 series modules, and the communication method adopts the ASCII code communication protocol or the Modbus RTU communication protocol. The baud rate can be set by the code. Programming.

The WJ65 series products are based on the intelligent monitoring and control system of single -chip microcomputers. All users set the addresses, Potter, data formats, verification, and status configuration information are stored in non -easy -to -miss memory EEPROM.

WJ65 series products are designed and manufactured according to industrial standards, and 3000V trilaterals between signal input, output and communication interfaces have strong anti -interference capacity and high reliability. Work temperature range-45 ℃ ～+85 ℃.

Function introduction:

WJ65 remote I/O module can be used to measure the eight -way switch signal, and there are eight -way switch output.

1. Input and output of switching signals

8 -way switching signal input, you can connect to the connection and wet connection point. For details, please refer to the wiring diagram section.

2. Communication protocol

Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface, indicate when ordering.

Communication protocol: Support two protocols, commands defined character protocols and Modbus RTU communication protocols. The module automatically identifies the communication protocol to achieve network communication with multiple brands of PLC, RTU or computer monitoring system.

Data format: 10 bits. 1 starting position, 8 -bit data bit, 1 stop position, no verification.

Correspondence address (0 ～ 255) and Potter (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; the longest distance of the communication network can reach 1200 meters, and the cable connection is shielded by twisted.

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

3. Anti -interference

You can set up a puppet verification as needed. Inside the module, there is a transient inhibitory diode, which can effectively inhibit various waves and protect the module.
