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 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 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.

For operation without loss of performance: Unit is mounted on a rail in a metal enclosure (Buckeye SM7013-0 or equivalent) and I/O cables are routed in metal conduit connected to earth ground. 2. This device was designed for installation in an enclosure. To avoid electrostatic discharge, precautions should be taken when the device is mounted outside an enclosure.

EMC INSTALLATION GUIDELINES POWER AND OUTPUT CONNECTIONS Although this unit is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into the unit may be different for various installations. The unit becomes more immune to EMI with fewer I/O connections.

INPUT CIRCUITS, SENSOR CONNECTIONS AND CONFIGURATION SWITCH SET-UP The Model IFMA uses a comparator amplifier connected as a Schmidt trigger circuit to convert the input wave form into the pulse form required for proper circuit operation. Three set-up switches are used to configure the input circuit to accept signals from a wide variety of sources, as follows: S1 - ON: Connects a 1 K pull-down resistor for sensors with sourcing outputs. (Maximum sensor output current is 24 mA @ 24 VDC output.

OUTPUT INDICATION Over range on the output : The Output LED (red) turns on and the Output is “clamped” at the maximum level. Low Frequency Cut-Out : The Output LED (red) turns on to indicate the input frequency is below the Zero Frequency setting. Invalid Entry during Set-up : The Input LED (green) and the Output LED (red) alternately blink until a valid entry is made.
