Model selectioni

Input and Channel Code : Communication interface
Channel codei 01 i 08i number of channel
01:1 channel 4-20mA/0-20mA signal input 485i output is RS-485 interface
02:2 channel 4-20mA/0-20mA signal input 232i 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.
