The model IFMA accepts a frequency input and outputs an analog voltage or current in proportion to the input frequency, with 0.1% accuracy. The full scale input frequency can be set to any value from 1 Hz to 25 kHz, either with a frequency source or digitally with the on-board rotary switch and pushbutton. The IFMA utilizes a seven position DIP switch, a rotary switch, a pushbutton and two indication LEDs to accomplish input circuit configuration, operational parameter set-up and input/output indication. The input circuitry is DIP switch selectable for a variety of sources. The indication LEDs are used during normal operation to display the input and output status of the IFMA. These LEDs are also used to provide visual feedback to the user of the existing parameter settings during parameter set-up. The IFMA operates in one of four output modes. The programmable minimum and maximum response times provide optimal response at any input frequency. The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including top hat profile rail according to EN50022 - 35 x 7.5 and 35 x 15 and G profile rail according to EN50035-G32.
