VideoQuip TTD-16A Sixteen alternate action function tone decoder

Product Description
The TTD-16 is a control system that allows 16 relay contacts to be controlled over a standard telephone line, using DTMF touch tone signals.
The TTD-16 may be set up to answer on 1, 2, 3 or 4 rings. The caller must first enter a 4-digit password to gain access to the system. The password is assigned using DIP switches inside the unit.
Once access to the system is obtained, each of the 16 relays can be easily controlled. A voice driven help menu is available to guide the user through the required steps for control of the individual relays. Each relay may be individually turned on or off, as required. The status of all 16 relays can be reported at any time.
A front panel LED is provided for off-hook status, indicating when the system is in use.
Connection to the telephone line is via a standard RJ-11 telco connector on the rear panel. Relay connections are made via screw clamp terminal blocks for each of the 16 relays.
Includes built-in power supply with an attached power cord.
Comes standard in a desk-top version, but can be ordered in a rackmount configuration.
