Function Description:

Product Overview:

WJ31 signal isolation D / A converter module can be used to output one channel voltage or current signal,
can also be used to output two common ground current or voltage signal.
1. Analog signal output
 12-Bit acquisition accuracy, all products signal input range have been calibrated. In use, users also can program
calibration easily.
 About the specific current or voltage input range, please see product selection. when need two channels signal output,
signal value must be the same.
2. Communication protocol
 Communication Interface: one channel standard RS-485 communication interface, or one standard RS-232
communication interface, specify when ordering.
 Communication Protocols: supports two protocols, characters protocol of the command set defined and MODBUS
RTU communication protocol. Can be programmed using the kind of communication protocol, can be achieved with
PLC, RTU of many Brands or computer monitoring system for network communication.
 Data Format: 10 Bits. 1 start bit,8 data bits,1 stop bit.
 Address: (0 to 255) and baud rate (2400,4800,9600,19200,38400 bps) can be set, the most long-distance about
communication networks is up to 1200 meters, through the twisted-pair shielded cable.
 Communication interface of high anti-jamming design, ± 15KV ESD protection, communication response time is less
than 100mS.
 3. Anti-jamming
 According to need to set the checksum. Module internal has transient suppression diodes, can inhibit a variety of surge
pulse, protection module, and internal digital filter can also be well suppressed from the grid frequency interference. 

The WJ31 series realize host RS-485/232 interface signal isolation converted into a standard analog signal, to control
the remote device. WJ31 products can be applied to RS-232/485 bus industrial automation control system,4-20mA /
0-5V/0-10V standard signal output, to control industrial site execution set equipment, control equipment and display
instrument.
Products include power supply isolation, signal isolation, linearization, D/A conversion and RS-485 serial
communication. Each serial interface can connect up to 256 pieces WJ21 Series modules, communication using ASCII
code or MODBUS RTU communication protocol, and its instruction set compatible with the ADAM modules, baud rate
can been set by the code, with other manufacturers control module hang in the same RS-485 bus for easy programming. 

WJ31 series products are based on SCM's intelligent monitoring and control system, users set the calibration value,
address, baud rate, data format, checksum status, and configuration information are all stored in nonvolatile memory
EEPROM.
 WJ31 products are according to industry standard design, isolation between signal output / communication interface,
can withstand voltage 3000VDC, high anti-interference ability and reliability. Operating temperature range is - 45 ~ +85
°C.
