MODEL IFMA - DIN-RAIL FREQUENCY TO ANALOG CONVERTER
DESCRIPTION
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 push-
button.
The IFMA utilizes a seven position DIP switch, a rotary switch, a push button
and two indication LED's 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 LED's are used during normal operation to display the input
and output status of the IFMA. These LED's 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 EN
50 022 - 35 x7.5 and 35 x 15, and G profile rail according to EN 50 035 - G 32.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
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.
