in London Architect with Soundweb London
Hello

I have a installtion containing a Soundweb London Blu-80 and Blu-10, and an electric screen and a videolift

My need is that I must create a bontons UP/Down for the videolift and the screen,

My problem is that how i have a open/close contactt in the control port of theSoundweb

NB : - For Videolift : 2 simple open/close contact in Soundweb control
- For the screen 1 contact (I need to use a 24v/220v realy)

the picture explains my need

    Hi there. The outputs of the BLU are not dry contacts, but TTL logic level outputs (5V.) I have used an RDL ST-LCR1 to create dry contacts from the control outputs. From this device you can then feed 12V or 24V to a 120V relay which would operate your lift. (I sometimes just used the 24V power supply powering the ST-LCR1 by jumping the power supply terminal on the ST-LCR to the dry contact) The ST-LCR1 has two form-C relays, so all you would need is one unit to create both the 'up' and the 'down' contacts (assuming they were always mutually exclusive and could be latching)

    I suppose you may be able to find a 120V relay that was TTL activated, but I have not researched it.
