Product Description
2 Channels 4-20mA to RS232 RS485 Converter with LED display


Model selection:
SYAD 02/04B - U(A)
02/04B  Channel choose
 02B:Two channel
 04B:Four Channel
U(A): input voltage or current signal            
U1:0-5V       A1:0-1mA          
U2:0-10V      A2:0-10mA       
U3: 0-75mV    A3:0-20mA     
U4:0-2.5V     A4:4-20mA                       
U5:0-±5V     A5:0-±1mA                         
U6:0-±10V    A6:0-±10mA                         
U7:0-±100mV  A7:0-±20mA
U8:Customized  A8:Customized
Note:SYAD02/4B module supports both RS232 and RS485 communication interface, the user can select the corresponding communication interface based on the use of the environment, but at the same time can have only one of the two interfaces work, or will cause interference.
