0066820 | DOLD

Speed and frequency monitor, 0066820, DOLD

The 0066820 is a speed and frequency monitor that serves the reliable frequency monitoring of alternating currents and the safe monitoring of the phase sequence resp. rotary direction of motors with 3-phase alternating currents. It is used to monitor the output frequency of inverters or the rotor frequency of slipring motors. An other application area is the monitoring of motors in crane plants. Using the front side display the parameters can be easily and comfortably adapted to the individual application or changed when necessary.
