Abstract

Układ sygnalizacji przepalenia bezpiecznika w barierze iskrobezpiecznej zwłaszcza do iskrobezpiecznych obwodów zasilających posiada za bezpiecznikiem (B) i równolegle do równolegle połączonych ograniczników napięcia (ON1, ON2, ON3) włączony dwójnik złożony z diody świecącej transoptora iskrobezpiecznego (TI), którego anoda przyłączona jest do pierwszych wyprowadzeń równoległych ograniczników napięcia (ON1, ON2, ON3), a katoda połączona jest szeregowo z rezystorem ograniczającym prąd (R1) i z drugiej strony podłączonym do drugich wyprowadzeń równoległych ograniczników napięcia (ON1, ON2, ON3). Analogowy styk transoptora iskrobezpiecznego (TI) przyłączony jest do zacisków kontrolnych (Z1) i (Z2) układu sterującego (US).The fuse burnout signaling system in the intrinsically safe barrier, especially for intrinsically safe power supply circuits, has, after the fuse (B) and in parallel to the voltage limiters connected in parallel (ON1, ON2, ON3), a two-wire consisting of a diode of an intrinsically safe optocoupler (TI), the anode of which is connected to the first terminals of parallel voltage limiters (ON1, ON2, ON3), and the cathode is connected in series with the current limiting resistor (R1) and on the other side connected to the other terminals of parallel voltage limiters (ON1, ON2, ON3). The analog contact of the intrinsically safe optocoupler (TI) is connected to the control terminals (Z1) and (Z2) of the control system (US).
