The TDU (Talking Display Unit) is a completely solid state (no moving parts) digital message player, which is specifically designed for a wide range of interactive messaging applications. Up to 250 messages can be loaded onto the supplied SD card.
TDU will play a message as soon as it is triggered by a switch, a sensor or at a user programmed time interval. TDU can play 1 message only, or you can load up to 250 messages onto the SD card and 1 message will play for each remote switch event..
Our alternative model TDU/S has an optional serial port (RS232) instead of a switch input port. It will play 1-250 messages as required under the control of a remote PC or other intelligent device.
