Abstract
The circuit has a pair of control signal inputs (E1,E2) for low and high voltage potentials, coupled via respective voltage dividers (R1,R2;R3,R4) to the bases of a pair of corresponding transistors (Q1,Q2). The collectors (2) of both transistors are coupled to the controlled relay (K1), their emitters coupled to respective diodes (D1,D2). A third and fourth voltage divider (R5,R6;R7,R8) are coupled to the base of two further transistors (Q3,Q4), having their collectors coupled to the corresponding bases of the first two transistors.
