Produktinformation
One of the most common causes of difficulty with 4-20mA systems has to do with current loop error, caused by common -ve or +ve terminals. Some devices, such as PLCs, can accept several 4-20mA inputs, and it is not unusual to find that all – ve terminals are connected to the same point.
Because 4-20mA is a current signal, it can only be properly shared with several devices by connecting them in series, but the common -ve connections in PLCs and other similar devices can upset a series loop. An isolator or two can solve this problem.
