Impulse Relay

The Im­pulse Relay M3 is used when loads need to be switched on for a de­fined pe­riod of time and then switched off again with one input sig­nal. Please spec­ify the de­sired out­put pulse length in the pur­chase order.

 

Function

Di­a­gram S1, S2: The sup­ply volt­age is con­nected to ter­mi­nal 30. When a volt­age pulse (trig­ger) is ap­plied to ter­mi­nal 15 the relay im­me­di­ately picks up for the spec­i­fied time pe­riod and drops out at the end of the time pe­riod cre­at­ing an out­put pulse of the spec­i­fied length. The out­put pulse length is in­de­pen­dent of the pulse length ap­plied to ter­mi­nal 15 (sin­gle shot trig­ger).
Di­a­gram S3: The sup­ply volt­age is ap­plied to ter­mi­nal 87z. When a sig­nal volt­age is ap­plied to ter­mi­nal 15 the relay im­me­di­ately picks up for the spec­i­fied time pe­riod and drops out at the end of the time pe­riod. If the sig­nal volt­age on ter­mi­nal 15 is re­moved prior to the end of the spec­i­fied out­put pulse length the relay drops out im­me­di­ately.
Di­a­gram S2 and S3: Out­put con­tacts are elec­tri­cally sep­a­rated from input con­tacts which al­lows for relay com­bi­na­tion so­lu­tions. In this con­fig­u­ra­tion the relay is po­ten­tial-free and can be used to switch al­ter­nat­ing volt­ages. Please refer to the chap­ter hous­ing and base plates for ad­di­tional hous­ing op­tions.
