INTERFACE DTMF 8 CONTACTS

ref. INTERFACE DTMF
  • This interface is perfectly suited to be inserted between the MOD TEL2 or the MOD TEL SIP and the NPX-8000 audio matrix in order to trigger from any phone the pre-programmed messages of NPX matrix on the SD card.
  • This interface has 8 relay outputs activated by combination of key via its DTMF decoder, just pair it with the audio output of the TEL MOD.
  • The phone's key 1 triggers relay 1 and so on up to 8, this default code can be easily changed by the user with a more complex sequence to avoid any mishandling (Example 1001 to activate relay 1; 2002 for relay 2 etc....)
  • Each relay output offers the possibility of having a NO (Normally open) or NC (normally closed) contact.
  • This product can be powered by continuous voltage between 12VDC and 36VDC.
