Abstract

The invention relates to an electronic safety limiter. In this limiter which comprises a self-controlled regulator 1 to 6 and two relays 8, 9 whose contacts are connected in series, the regulator containing a generator of real values 4 containing a temperature sensor, a generator of datum values 3, a threshold value switch 5 downstream of which a triggering circuit 7 is connected, the two relays are controlled by a single regulator and the output signal of an oscillator 1 constitutes the datum value of the regulation circuit. Application especially to temperature limiters in heating installations. <IMAGE>
