Description
Frequency monitor relay switches-on or -off consumer when certain threshold frequency is exceeded or falls below.
Application Examples
Automatic start
Rotation measurement
Flow rate
Function The relay will measure a frequency and switches consumer off/on as soon as a certain threshold frequency at terminal 15 is exceeded or falls below.The frequency thresholds can be user defined, frequency range 10 - 1.000 Hz. Also a combinations with delay times are possible.
For different housing please see in the chapter housing and baseplates.
