SYAD02/4B series achieve the signal acquisition between sensor and the host to test analog signal or 
control remote device. The configuration software can be used for a variety of sensors including analog 
input, analog output, and digital signal input / output (I / O), SYAD02/4B series products can be used in 
industrial automation RS-232/485 bus system,4-20mA  / 0-10V signal measurement, monitoring and 
control, small-signal measurement, and industrial-site signal isolation and long-term transmission and so 
on.  

Products include power supply isolation, signal isolation, linearization, A/D conversion and RS-485 
serial communication. Each serial port of the maximum 256 SYAD02B series of modules, means of 
communication using ASCII character communication protocol or MODBUS RTU communication 
protocol, its instruction set compatible with the ADAM modules, the baud rate is set by the user, with 
other manufacturers control module hanging in the same RS-485 bus, to facilitate computer 
programming.
