I-PHD-11HD-21
Uhlolojikelele
Isithiyo sokuphepha esisodwa ohlangothini lokutholwa: PHD-11HD-21, okokufaka kwe-analog nokuphumayo, okokufaka okukodwa kanye nokuphumayo okukodwa.
Umgoqo ohlukanisiwe ungahlukanisa futhi udlulisele isignali engu-4~20mA noma isignali ye-DC 4~20 mA ekhiqizwe isidlulisi endaweni eyingozi endaweni ephephile. Uma isidluliseli siyisistimu enezintambo ezimbili noma ezintathu, umgoqo wokuphepha unikeza amandla kusidlulisi.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele.
Lo mkhiqizo usekela isignali ye-HART ne-alamu yokunqamula.
