AT20B5

AT20B5 is an AT-B5 AC current transducer. It is a split-core transducer for the electronic measurement of AC waveform currents, with galvanic separation between the primary circuit and the secondary circuit. The 0-5V DC switch voltage output is proportional to the RMS value of the primary current. Typical applications include automation and supervision (current measurement for process regulation by distributed PLCs or remote control (e.g. SCADA software)), safety and condition monitoring (load monitoring for protection systems and predictive maintenance (e.g. conveyers, pumps or HVAC motors).
