Snom PA1 Contact Closures

We are looking for a way to create a dry contact State change such as a switch open/close. Is there something available that will allow us to do this?



Best Answer

Hello John,


the PA1 puts 0V or 3.3V on the output PIN (0=PIN is off, 3.3=PIN is on). If you need a dry contact you have to connect a relay to the PA1, you can directly connect a solid state relay (Eg.: http://wiki.snom.com/Supported_relays ) or you can build a circuit: http://wiki.snom.com/Relaysboard_pcb to connect an electro-magnetic relay.


Best regards,
