The arrangement includes a control arrangement (5) which produces the control signal (ST) from an entered instruction signal (SA), and an output arrangement (40) with a signal input (E40) coupled to the control arrangement, which stores the control signal and provides it at its signal output (A40) in response to a release signal (SF). A control arrangement (50) connected with the output arrangement, reads the stored control signal (ST') at a read-back output (R40) of the output arrangement, and produces the release signal, if the read back control signal corresponds to the entered instruction signal. The output arrangement comprises a relay (10) which is supplied on one hand with the produced control signal and on the other hand with a hold voltage (UH), in such way, that the relay changes its condition at the appearance of the control signal, and the respectively new condition is stored by storing the produced control signal at a supplied hold voltage. |
