Product Description
RS485/232 to 4-20ma/0-5V/0-10V/0-2.5V D-A Converter
Model Selection:
ISODA  O□-   □
Output voltage or current value         Communication Interface
O1:4-20mA                                    485: out is RS-485 interface 
O2:0-20mA                                    232: out is RS-232 interface
O4:0-5V                                      232/485:out is one RS232 or RS485 interface
O5:0-10V                                        (Key-press Choice)
O9: 0-±20mA
O10: 0±10V
Note:When interface type is 232/485, default is RS485 output, user can switch between RS485 and RS232 by pushing down 2 buttons inside the chassis. When both buttons are pushed down, output is RS232,or is RS485 output.
1. ISODA O1-485   Means 4-20ma signal output,output is RS485 interface
2. ISODA O4-232   Means 0-5V signal output,output is RS232 interface.
3. ISODA O7-232/485 Means 0-±5V signal output,output is RS485 or RS232 interface
(Key-press Choice)
