product description:

WJ32 Series Product Realization Host RS-485/232 Interface Signals Convert to standard analog signals to control remote devices. WJ32 series products can be applied to RS-232 / RS-485 bus industrial automation control systems, 4-20mA, 0-5V, 0-10V and other standard signal output, used to control industrial field executive equipment, control equipment, and display instrumentation, etc. Wait.

Products include power isolation, signal isolation, linearization, D / A conversion, and RS-485 serial communication. Each serial port can be connected up to 255 WJ32 series modules, the communication method uses the ASCII code communication protocol and the Modbus RTU communication protocol, automatically identifies the communication protocol and reply, the baud rate can be set by the code, can hang the same RS with other manufacturers. The -485 bus is easy to program.

WJ32 series products are based on the intelligent monitoring and control system of single-chip microcomputers, all user set calibration values, address, baud rates, data formats, checksum, and other configuration information stored in non-volatile memory EEPROM.

WJ32 series products are designed, manufactured, and signal output / communication interfaces can withstand 3000VDC isolation voltages, strong anti-interference ability, high reliability. Working temperature range - 45 ° C ~ + 80 ° C.

WJ32 Features Description:

WJ32 signal isolation D / A conversion module can be used to output current or voltage signals of 4 channels.

1, analog signal output

12-digit output accuracy, all signal output ranges before the factory are all calibrated. In use, the user can easily program calibration.

Please see the product selection, 4 output selection must be the same.

2, communication protocol

Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface, the order selection is indicated.

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.

The communication address (0 ~ 255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200 bps) can be set; the longest distance of the communication network can reach 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.
