How to dismantle system 5000First, remember to demount the connectors with hazardous voltages. By liftingthe bottom lock, the module is detached from the DIN rail as shown in picture 1.Then, by lifting the upper lock and pulling the front plate simultaneously, the PCBis removed as shown in picture 2.Switches and jumpers can now be adjusted. By opening the front, theprogramming connector is accessible as shown in picture 3.PROGRAMMABLE f/I - f/f CONVERTER5223• Pulse calculator• Frequency generator• Galvanic isolation, optional ATEX Ex• Analogue current and voltage output• PNP / NPN output, optional relays• Universal supplyPicture 1: Separation from DIN rail.Picture 3: Access to programmingconnector.---------------------------------------------------------------------------------------Supply voltage:24...250 VDC24...230 VAC---------------------------------------------------------------------------------------INPUT RANGE:Frequency:Sensor types:0...20000 HzNamur, tacho,NPN, PNP, TTL, S0---------------------------------------------------------------------------------------OUTPUT RANGE:Current and voltage output:0...20 mA / 0...10 VRelay outputs:0...20 HzNPN and PNP output as f/f:0...1000 HzNPN and PNP output as generator: 0...20000 Hz---------------------------------------------------------------------------------------In generalBy way of a standard PC and the Loop Link programming kit, the PRecon 5223f/I - f/f converter is configured acc. to the requested function.Alternatively, the 5223 may be delivered fully-configured acc. to your specifications,see the options index in the data sheet.Typical pulse sources are flow meters, tacho generators, mechanical switches, orinductive proximity sensors.Picture 2: Removal of PCB.22 23

ApplicationsThe f/I function performs frequency to current and voltage conversion.The output can be programmed to show period, meaning that the inputfrequency can be converted to a linear time signal.The digital outputs are used as e.g. a frequency watch for speed control or as awindow comparator having one status between 2 limits and the opposite statusoutside these limits.The f/f function can be used for pulse division or multiplication and as a buffercollecting fast pulse trains. The input pulses are calculated, counted in a buffer,and sent to the output as a pulse train with the programmed pulse width.A scale factor may be entered in all functions. Using both digital inputs, pulseaddition or subtraction are possible. This function permits readout of the actualconsumption at measurement of e.g. liquid flows forward and backward.The frequency generator function is used as e.g. a time base orclockgenerator.The 2-phase encoder, or directional f/I conversion, converts 2 90°-phased digitalinputs to an analogue speed signal with digital output for directional indica tion.ATEX Ex units have input for mechanical contact and NAMUR inductiveproximity sensor.Technical characteristicsInputs2 programmable inputs for standard pulse generator connection.Normally, the auxiliary supply and trigger level follow the sensor type, but thesecan be programmed to other values.At contact input, the 50 Hz filter should be applied.The PRecon 5223 is protected against polarity reversal on input and supply.Standard voltage output (pin 12) is obtained by leading the current signal (pin13) through an internal shunt resistor (pin 12). At voltage signals in the ranges0...1 VDC, a 50 Ω shunt (JP1) is applied; in the ranges 0...10 VDC, a 500 Ω shunt(JP2) is applied.Digital output(s)The action on the outputs can be inverted, and the hysteresis can be set acc. toyour specifications.At power up, shifts on the outputs can be delayed for up to 999 s.NPN and PNP outputs for external relay, electromechanical counter, PLC input,or equivalent load.The outputs are current-limited by way of PTC resistors.Relay outputsThe PRecon 5223 can be delivered with 2 relay outputs that are programmedindividual ly.Status indicationThe 5223 is equipped with 5 front LEDs.f1 and f2 in:Dig. out. 1 and 2:Error:Indicates an active input (non-active at NPN input).Indicates active output.Programmable by use of PReset to indicate sensorerrors.Analogue outputThe current and voltage signals are galvanically separated from the supply andthe inputs.The analogue current and voltage output can be scaled acc. to your choice inrelation to the digital input. Max. zero offset is 50% of selected measurementrange. Programmable response time.Short-circuit-protected output.When both current and voltage signals are used simultaneously, the mA loop toground must pass through the internal shunt.24 25
