The RCTrms has an industry standard 4-20mA output making it ideal for process control, status alarming or system monitoring purposes.
The RCTrms is an ac current transducer for permanent installation.
Simple to install and easy to retrofit it combines the benefits of a thin, flexible, clip-around Rogowski (sense) coil with a signal conditioner providing accurate, true rms measurement, of ac current.
Typically the RCTrms is used with SCADA systems, PLCs, data loggers and protection equipment.
