Product Description
RS232/RS485 Digital Signal to Analog Signal Isolation D / a Converter

Model Selection:


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)
O6: 1-5V
O7: 0-± 5V
O8: User-defined
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)
