I have a amplifier which has an input of 4-20mA for command.
I have a signal source which is capable of only -10V to + 10V.
I want a converter in between to convert the input as below :
- 10V input : 4mA output
0V input : 12mA output
+10V input : 20mA output.
Any suggestions ? Circuits ??
Thanks in advance.
