Functioning
The receiver is actuated by means of a current pulse triggered by pushing any bell push connected to the relay. The receiver is deactivated by another pulse or after a preset time. Long press, lasting a minimum of 2 seconds, press the button will attach the contact permanently in continuous lighting mode until another pulse has been sent to deactivate the relay.
The relay does not “memorize” the position of the relay contact, i.e. in case of supply voltage decay and the subsequent return of supply voltage, the relay contact will be set in the off position. Such a solution prevents the automatic actuation of the receivers controlled that might occur without proper supervision after a long-lasting decay of supply voltage.
Tips
Illuminated buttons
Due to the low supply voltage, illuminated buttons should not be used. Maximum load current The contact current given in the technical data is the maximum value and may be subject to restrictions – more information . If the information provided indicates that the relay in the device is insufficient, it is recommended to use an external switching element (e.g. contactor) adapted to switch large surge currents. State memory The relay version with the letter “M” has a contact position memory, i.e. after the power is turned on, the relay state that was at the time of the power cut will be restored.
