FMU Frequency Transmitter
Brand: KOBOLD Instruments, IncThe model FMU frequency transmitter transforms a frequency signal to a standardized analog signal. The housing is state of the art and designed for standard rail installation. 230 Vac, 115 Vac or 24 Vdc are available as supply voltages.
The transmitter as two separate modules, output and power which are electrically isolated from each other. The isolating voltage is 2 k Veff. The process measurement signals 0-20 mA, 4-20 mA or 0-10 V are available as outputs.
Input and output signals are selected by means of different terminal assignments and jumpers.
Potentiometers are used for remote adjustment.
