DTMF (SMT) Decoder Module with 6 outputs & Morse Transpond.

Our DTMF decoder module has 6 NPN open collector Darlington outputs that can be switched on/off remotely with or without a 4 digit security code (ID). The decoder also has a TX keying output to key a transmitter for transponding a Morse confirmation. An audio output is included for the Morse audio tones.

By default the input has unity input gain which is ideal for connecting to many audio sources. There are links on the PCB to re-configure the audio input for the alternative Electret microphone option. 
(Microphone not supplied).

The PCB is a high quality Gold Plated double sided PTH (plated through hole) 1.6mm FR4 (Fibreglass) board 44 x 38mm in size.
