ABSTRACT:
A circuit arrangement in a line which transfers a condition by means of a semiconductor switching arrangement which produces a logic condition associated with monitored data processing equipment. The semiconductor switching arrangement has a thyristor characteristic and consists of a pair of transistors which form a control circuit with one of the transistors, particularly the emitter thereof forming the anode point of the semiconductor arrangement. This one transistor is also provided with a base-emitter resistor which is dimensioned corresponding to the sum of the collector-base residual currents of the pair of transistors in the control circuit when the semiconductor switching arrangement is in the blocked or non-conducting condition.
