IP WatchDog HWg-WR02a: ping restarter, web watchdog
Monitorizeaza doua dispozitive prin IP (PING/WEB) sau o linie seriala (RS-232), si le restarteaza automat pe fiecare, daca inceteaza sa raspunda – releu de restartare ping autonom.
Note: Shorted version - full details in english version.
WatchDog-ul IP WR02a monitorizeaza periodic functionarea unui dispozitiv transmitind sau receptionind un mesaj predefinit “Sint in viata si OK”. Acest semnal poate fi receptionat pe IP (PING or WEB) sau RS-232 (port serial). Daca raspunsul corect nu e receptionat la timp, dispozitivul supravegheat este restartat, folosind un releu.
WatchDog-ul IP este un releu ping pentru 230V sau simplu, un restarter ping cu doua relee de iesire. Acesta poate monitoriza doua dispozitive (doua canale independente, doua relee).
Fiecare canal poate fi folosit pentru restart autonom sau pentru comutare on/off, ca releu web.
WatchDog-ul IP WR02a permite configurare flexibila – metoda de detectie a functionarii, timp de asteptare in inchidere la restart.
Aplicatiile industriale beneficiaza de montarea pe sina DIN si de releele interne care pot comuta direct 110/230VCA, max 16A. Problemele d efunctionare sint detectate prin 5 metode distincte, separat pentru fiecare canal (Ping Tx/Rx, Web page Tx/Rx, RS-232 Rx data).
