Product Overview:
 WJ28 series products realize the signal acquisition between sensor and host, to measure analog signals. WJ28
products can be applied to RS-232/485 bus industrial automation control system,4-20mA / 0-5V signal measurement,
monitoring and control,0-75mV ,0-100mV and other small-signal measurement and signal isolation and long-term
industrial transmission and so on.
Products include power supply isolation, signal isolation, linearization, A/D conversion and RS-485 serial
communication. Each serial interface can connect up to 255 pieces WJ28 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.
