Brojač koji može da radi kao klasičan brojač sa tasterom, nekim senzorom tipa NPN ili PNP ili da radi u modu merenja dužine sa enkoderom. Karakteristike: - Model: MYPIN FH4-4CRNB - Ulazni signal: 5-30 V - kvadratni ili sinusni signal - Brzina brojanja: 5000 impulsa u sekundu maksimalno - Opseg: -1999-1999 - Prikaz: 0.000-9999 - Relej: 3A / 250V / NO+NC (normalno otvoren i normalno zatvoren kontakt) - Napajanje: 90-260 V AC/DC - Temperatura okruženja: 0-50 stepeni - Dva ulaza IN A i IN B - 24V i GND poseduje uređaj - Dimenzije: 48 x 48 x 80 mm Uređaj poseduje 4 moda rada ulaza i 6 modova rada izlaza. Podešavanje ulaznoga tipa senzora NPN ili PNP, a u slučaju korišćenja klasičnoga tastera paralelno mu dodati kondenzator. Na taster SET se podešava zadata vrednost na kojoj pali rele. U podešavanjima se sam resetuje rele (parametar t01) ako nije u modu mauelnoga reseta gde se spolja resetuje tasterom. Dugim pritiskom na SET se ulazi u podešavanja: - Pc - Množilac impulsa ulaza, 0,000-9,999, parametar za dužinu - oUt - Modovi izlaza - t01 - Vreme nakon koga se resetuje rele - InP - Modovi ulaza - dP - decimalni prikaz - nPn - Izbor ulaza NPN ili PNP - LoCK - Zaključavanje parametara
