MultiTek Frequency Single Transducer

M100-FA1 Self powered true zero outputs
M100-FL1 Auxiliary powered live zero outputs
M100-FX1 Auxiliary powered true zero outputs

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 75-125% 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 process control etc.
