Transducers for frecuency
• only 22,5mm width
• Load resistance up to 1000 Ohm @ 20mA
The transducer series CFR are to be applied for measuring frequencies in a range 40 to 70Hz (to be specified). Rated input voltages are from 50 to 720V. The dynamic range goes from 20 to 120%.
For mounting on DIN rail (DIN EN 50 022).
The input value is being galvanically insulated (5kV/1min), a frequency
proportional value is calculated and this is converted into a proportional
and load-independent DC current (or DC voltage). Auxiliary supply is required, standard 24VDC or 230VAC.
f1 = lower measuring frequency (can’t be used for the determination of error limit).
f2 = upper measuring frequency (final value of measuring range for determination of the error limit).
