WJ203 Function Introduction:
 The WJ203 signal isolation D/A conversion module can be used to output one current or voltage signal.
 1, Analog signal output
 12 bit output accuracy, all signal output ranges have been calibrated before the product leaves the factory. During use,
 users can also easily program and calibrate themselves.
 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
 RTUcommunication protocol. The module automatically recognizes communication protocols and can
 achieve network communication with various brands of PLCs, RTUs, or computer monitoring systems.
 Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit.
 The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set;
 The communication network can reach a maximum distance of 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
 Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively
 suppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power
 frequency interference from the power grid.
