Description: 2 brand new DOLD Frequency Relay BA 9837.11Article number: 0054197 Variant: BA9837.11 40-120HZ UH AC230V50/60HZ The frequency relay can be used especially in applications where the rotor frequency of a slip-ring motor must be measured. The rotor frequency is reciprocal proportional to the speed (see diagram rotor frequency at contercurrent braking). This behaviour allows to find speed depending switching values and can be used for start up and contercurrent braking of motors on cranes. Technical specifications Measuring range max.: 600 Hz Standard measuring range: 30 - 90 Hz 1- / 3-phase: 1 Operate delay: Yes Output contacts: 1 C/O contact, 2 C/O contacts Width: 45 mm Enclosure design: Switch cabinet Auxiliary voltage required: Yes Type: BA 9837
