Using a Rhino FXS Analog Chanel bank to actuate a relay
This works great but the system is in a remote location in the facility so it takes a bit of walking to get to it. What i'd like to do is try to hook up a NC relay between the surge protector and the wall and have an open channel on the Rhino actuate the relay to basically turn the power off to the system any time you dial a specific extension.
According to the datasheet the Rhino itself has a line current limit from 18ma to 45ma and it emits standard telephone line voltage....i can also configure the ring cadence...so i can probably set the ring duration long enough to actuate the relay before it cuts the system off (which would then return the relay back to closed)
i'm having trouble finding out what the actual output voltage on the analog line and a general lack of schematics to try to make this work
so...if anyone wants to have a little fun attempting to design a relay that can be actuated by a telephone...please reply
