This TDS12124 miniature AUTOBUS interface, available in two versions, is a four channel Voltage free contact input interface for built-in applications. It is designed to fit in the smallest available wall box, just behind your favourite pushbuttons. Any contact or sensor contact can be integrated, any brand, any colour, any design.

This is the basic version with AUTOBUS connection and inputs for four voltage free contacts.

This means, ‘no architectural limits’!

If you need feed-back signals and/or IR-receiver input for IR remote control, please use TDS12125 instead.
