WJ203 Function Introduction:

WJ203 General Parameters:

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. Duringuse, 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 MODBUSRTU communication protocol. The module automatically recognizes communication protocols andcanachieve 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 beset;
The communication network can reach a maximum distance of 1200 meters and is connected throughtwistedpair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication response timelessthan 100mS. 3, anti-interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power
frequency interference from the power grid.
