The AD-TV 588 GVD is used for measuring the rms value of alternating current via a built-in current transformer up to 5A or via an external clamp on / split core current transformer up to 600A. The detected current is outputted as a galvanically isolated standard current signal in the range 0 to 20 mA and as a standard voltage signal in the range 0 to 10 volts. An additional relay output can indicate a limit value or a window. All parameters such as range, output range, relay functions, limiting values, etc. can be freely set via the configuration software.



Measuring the current of single-phase loads up to 600A. Monitoring of current consumption to certain limits with hysteresis threshold by limit function. Monitoring a certain range of the current consumption by window function.
