Product Description

The Ramsey TT7 Touch Tone Decoder Kit decodes DTMF Touch Tones from telephone, radio, etc. 

  • 20mA output drives relays, LED's, digital devices, etc.
  • Telco CO quality decoder with stable crystal control
  • Decodes 0 thru 9, *, #, A, B, C, D
  • You can strap the TT-7 for detection of any single digit, including the secondary A, B, C, D digits. When the decoder detects the selected digit, it will provide a closure to ground for driving a relay, lamp, sounder, or other such load of up to 20 mA. A commercial central office quality decoder IC chip is used, making the TT-7 extremely reliable, fast and sensitive. You may connect the TT-7 directly across the speaker or detector output on any receiver, and in fact, we even detail how it may be connected directly to a telephone line. We designed the TT-7 to be small enough (about 2 square inches) to fit in many radios for easy installation. If your needs are simply single function remote tone control, the TT-7 is for you. (For multifunction remote control, use our TG2 Tone Grabber). Runs on 5VDC. Size: 1 1/2" x 7/8" x 2 1/4".
