Model selection:
ISOAD A -
Input and Channel Code Communication interface
Channel code:01 ~ 08,number of channel
01:1 channel 4-20mA/0-20mA signal input 485: output is RS-485 interface
02:2 channel 4-20mA/0-20mA signal input 232: output is RS-232 interface
03:3 channel 4-20mA/0-20mA signal input
.........
08:8 channel 4-20mA/0-20mA signal input
Note: If the selected product has less than 8 channels, it is the same externalview as that of AD A08, wiring scheme, and communication protocol. The only difference is that the selected one has less channels to measure data.
Mode selection eg.1: Model:ISOAD A01-485 Indicates 1 channel, 4-20mA/0-20mA signal input,input is RS485 interface
Mode selection eg.2: Model:ISOAD A06-232 Indicates 6 channel, 4-20mA/0-20mA signal input,input is RS-232interface
Mode selection eg.3: Model:ISOAD A08-485 Indicates 8 channel, 4-20mA/0-20mA signal input,input is RS 485interface
