The Im­pulse Relay Ad­justable is used when loads need to be switched on for a de­fined pe­riod of time and then switched off again with one input pulse. The out­put pulse length is user-ad­justable via po­ten­tiome­ter set­ting within five avail­able stan­dard time in­ter­vals. Cus­tom time in­ter­vals are avail­able on re­quest. Please spec­ify the de­sired stan­dard time in­ter­val in the pur­chase order.

Function

Di­a­gram S1: The sup­ply volt­age is con­nected to ter­mi­nal 30. When a volt­age sig­nal is ap­plied to ter­mi­nal 15 (trig­ger) 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 spec­i­fied length. The out­put pulse length is in­de­pen­dent of the volt­age sig­nal length ap­plied to ter­mi­nal 15 (sin­gle shot trig­ger).

Di­a­gram S2: 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. Out­put con­tacts are elec­tri­cally sep­a­rated from input con­tacts which al­lows for relay com­bi­na­tion so­lu­tions.

The de­sired out­put pulse length is user-ad­justable via po­ten­tiome­ter set­ting. Please refer to the chap­ter hous­ing and base plates for ad­di­tional hous­ing op­tions.
