Title: Opto-electronic simulator circuit for excess voltage safety relay - is tolerant of considerable voltage deviations without reducing line insulation using two shunting bridge resistors
Inventor: EMDE KURT-LOTHAR DIPL ING
IPC: H04M7/00
Filed: 1979-06-26
Abstract: The solid state version of a relay contactor (K) is made up of two complementary transistors (T4,T5) the bases of which are interconnected via a light-sensitive element (J33). At least one of the diodes in the bridge is a l.e.d. which becomes transitionally conductive when large speech - or spurious AC signals - are superimposed on the d.c. line voltage. Any light emitted by the diode increases the electron flow in the light sensitive element (J33) causing a resistance reduction across the transistor pair. Excess voltage energy is consumed in resistors (Lb,La) when the transistors become conductive and is proportional to the light quantity emitted by the l.e.d., ie. proportional to excess voltages on the line.
