Frequency Transducers

Description

DIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN  rail cases

Application

Used to convert various inputs into standard DC signals for driving panel meters and for use in control devices.

Selection Guide
M100-FA1 Self powered true zero outputs
M100-FL1 Auxiliary powered live zero outputs
M100-FX1 Auxiliary powered true zero outputs
Typical Applications

The M100 series of frequency transducers are designed to measure frequency in single and 3 phase systems. The A.C. Input is converted to a D.C. output that is directly proportional to the change in input frequency within a specified span. The M100-FA1 is self powered (No auxiliary required). The working voltage range is 75% to 125% of the nominal voltage.

The M100-FL1 is auxiliary powered. The outputs are live zero, either 4mA or 1 volt. The auxiliary enables the working voltage range to be 15%-125% The M100-FX1 is essentially the same as the FA1 but an auxiliary is provided to enable the unit to have a working voltage range of 15%-125%. All types of the above frequency transducers are typically used to monitor and control frequency in such applications as 3 phase mains supplies, A.C. Generating sets and processing control etc.
