RS485 signal acquisition module


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

8 inputs channel Current/Voltage signal to RS485/232 Converter
