Isolation 0-20mA/4-20mA To RS485 Or RS232 Data Acquisition

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   ISOAD Series 4-20mA to RS485/RS232 Converter Inroduction: (typical @ +25℃，Vs is 24VDC (It is recommended to use power supply under high stability and precision environment.)
