V/I Converters for Process Control

2B20 & 2B22 Translate 0 to +10V to 4 to 20mA; 2B20 Shares System Common; 2B22 Has 1500V I/O ISOLATION

Many of our readers work in fields where analog transmission of information is in the form of signals (usually voltage) referenced to zero: zero is either at one end of the range or in the middle. In the world of process control, however, analog information is more-often-than-not transmitted in the form of current variation from 4 to 20mA. Read full article
