Time Relay Switch On Delay

The Time Relay Switch On Delay M3 is de­signed for time-de­layed switch­ing on of loads. Please spec­ify the de­sired switch-on delay time in the pur­chase order.




Di­a­grams S1, S2, S3: The sup­ply volt­age is con­nected to ter­mi­nals 30/87z. When a sig­nal volt­age is ap­plied to ter­mi­nal 15 (trig­ger) the relay out­put will en­er­gize after the pre­set switch-on delay time. When the sig­nal volt­age is re­moved from ter­mi­nal 15 the relay out­put will switch off im­me­di­ately.

Di­a­gram S2, S3: Out­put con­tacts are elec­tri­cally sep­a­rated from input con­tacts which al­lows for relay com­bi­na­tion so­lu­tions. In this con­fig­u­ra­tion the relay con­tact is po­ten­tial-free and can be used to switch al­ter­nat­ing volt­ages.

Please refer to the chap­ter hous­ing and base plates for ad­di­tional hous­ing op­tions.
