MODEL IFMA - DIN-RAIL FREQUENCY TO ANALOG CONVERTER
DESCRIPTION
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 push-button.
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.
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.
and maximum response times provide optimal response at any input frequency.
standard DIN style mounting rails, including top hat profile rail according to EN
50 022 - 35 x7.5 and 35 x 15, and G profile rail according to EN 50 035 - G 32.
SAFETY SUMMARY
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
