66820

Produttore: DOLD

Descrizione:
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. Features Fast reaction time by measuring duration of cycle of input frequency Adjustable hysteresis Forcibly guided output contacts With pluggable terminal blocks for easy exchange of devices LED-indicators and 2 semiconductor monitoring output Simple and time saving setup without PC Comfortable, menu guided configuration via frontside display Reducing interruption time in production by extensive diagnostic functions Easy to integrate in existing drive applications
