Conversor F/L-F/F
Principais características

Programmable f/I converter
Programmable decimal divider / decimal multiplier
Programmable frequency generator
Relay output as option
Supply voltage 24 VDC


The user programmable version has a multifunction user interface consisting of three pushbuttons and a 3-digit LED displays.

Typical signalling devices may be pulse generators, for instance flow meters, tacho-generators or inductive sensors.
The f/I function is used for frequency to current / voltage conversion.
The f/f function is used for division or multiplication of pulses and as a buffer for fast pulse trains.
A frequency generator function e.g. used as a time base or a clock generator.


3 front LEDs, indicating active input (not NPN), Dig.out (NPN or relay 1) active output and a NAMUR input error signal.

Analog current output can be configured within 0...20 mA range.

Voltage output range is selectable between 0...10 VDC by use of internal jumpers.

Feature include input filter, contact filter and an auxiliary supply for sensor such as NAMUR and S0.

Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
