Programmable f/I - f/f converter

5223B

The 5223 transmitter can be configured with a standard PC and the Loop Link communications unit, or delivered fully configured.

The f/I function performs frequency to current and voltage conversion.
The f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains.
A scale factor may be entered in all functions. Using both digital inputs, pulse addition or subtraction are possible.
The frequency generator function is used as e.g. a time base or clock generator.
Input and supply polarity reversal protection.
Current and voltage output signals galvanically separated from the supply and the inputs.
Programmable digital outputs including NPN, PNP or relay options.
ATEX units have input for mechanical contact and NAMUR inductive proximity sensor.

5 front LEDs, indicating f1 and f2 active inputs (not NPN), Dig.out.1 and 2 active outputs, and a programmable error signal.
Analog current output can be configured to any current within 0...20 mA range.
Voltage output range is selectable between 0...10 VDC and 0...1 VDC by use of internal jumpers.
