Description

  

   <Desc/Clms Page number 1> 
 



    Schalteinrichtung   für   Signalrückmeldungen.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 oder   Durchschlagen   des Kondensators wird der in der Wicklung 12 fliessende Strom in der Phase so verschoben, dass ein Ansprechen des Relais nicht erfolgt. 



   An Stelle der Rückmeldung oder mit dieser zusammen kann auch eine Abhängigkeit zwischen mehreren Signalen, z. B. die   Bloekabhängigkeit   beim selbsttätigen Block, bewirkt werden. 



   PATENT-ANSPRÜCHE : 1. Schalteinrichtung für   Signalrückmeldungen,   bei denen die Rückmeldung über ein Relais erfolgt und dieses Relais durch eine Leitung mit der zu   überwachenden Vorrichtung   verbunden ist, 
 EMI2.1

 or breakdown of the capacitor, the current flowing in the winding 12 is shifted in phase so that the relay does not respond.



   Instead of the feedback or together with it, a dependency between several signals, e.g. B. the block dependency in the automatic block can be caused.



   PATENT CLAIMS: 1. Switching device for signal feedback, in which the feedback occurs via a relay and this relay is connected to the device to be monitored by a line,
 EMI2.1

Claims (1)

ein Gleichstromrelais verwendet wird, das über einen am zu überwachenden Apparat befindlichen Kontakt (61) und. einen Gleichrichter (5) gespeist wird. a direct current relay is used, which is connected to a device to be monitored Contact (61) and. a rectifier (5) is fed. 3. Schalteinriehtung nach Anspruch 1, dadurch gekennzeichnet, dass als Rückmelderelais (4) ein Weehselstromrelais verwendet wird, das über einen am zu überwachenden Apparat befindliehen Kontakt (61) und eine in Reihe mit einem Kondensator (8) geschaltete Spule (7) gespeist wird, wobei eines dieser beiden Elemente an der zu überwachenden Vorrichtung angeordnet ist. 3. Switching device according to claim 1, characterized in that the feedback relay (4) used is a alternating current relay which is fed via a contact (61) located on the apparatus to be monitored and a coil (7) connected in series with a capacitor (8) , one of these two elements being arranged on the device to be monitored. 4. Schalteinrichtung nach den Ansprüchen 1 bis 3, dadurch gekennzeichnet, dass der Speise- kreis des Rückmelderelais an die Sekundärwicklung eines Transformators (10) geschaltet wird, dessen Primärwicklung in Reihe mit der Rotlichtlampe (9) liegt. EMI2.2 4. Switching device according to claims 1 to 3, characterized in that the feed circuit of the feedback relay is connected to the secondary winding of a transformer (10) whose primary winding is in series with the red light lamp (9).
