ISO4021 Series Isolated 0-±100mV,0-±10V,4-20mA,0-±20mA to RS232/RS485 A-D Converter
Model selection:
ISO 4021 U(A) -
U/A: Input voltage or current signal Output: communication interface
U1:0-5V A1:0-1mA 232/485: Output is RS-232 or RS-485 interface
U2:0-10V A2:0-10mA
U3:0-75mV A3:0-20mA
U4:0-2.5V A4:4-20mA
U5:0-±5V A5:0-±1mA
U6:0-±10V A6:0-±10mA
U7:0-±100mV A7:0-±20mA
U8:Customized A8:Customized
Remark:When the communication interface is RS232, it should connect with RXD and TXD port; when the communication interface is RS485, it should connect with DATA+ and DATA- Port. RS232 and RS485 can't work at the same time.
E.g.
1: ISO 4021 A4-232/485 Means 4-20ma signal input, output is RS232 or RS485
2: ISO 4021 U1-232/485 Means 0-5V signal input, output is RS232 or RS485
3: ISO 4021 U5-232/485 Means 0-±5V signal input, output is RS485 or RS232
