RT0106 loop relay interface circuit
Overview:
The RT0106 loop relay interface circuit adopts a traditional transformer coupling scheme, which has good lightning protection effect, minimal signal distortion, extremely high common mode suppression ratio, and ideal ground balance, and can meet the requirements of system transmission indicators and safety. Meanwhile, due to the use of anti bell current impact circuits, the system can safely and reliably connect with various switches.
The RT0106 loop relay interface circuit adopts a high impedance signal channel. In the on hook state, the circuit will automatically switch to this channel to achieve audio signal transmission in the on hook state. This channel has minimal distortion and can reliably detect DTMF signals and FSK signals when on hook.
