Hi,
I am trying to use this relay to break a normally close TIP and RING lines of a telephone whenever i wish to block a call.
When an incoming call or outgoing call is recieved, it is compared to phone numbers stored in memory of the PIC microcontroller...once there is a match between the two numbers, the PIC microcontroller should send a signal to activate the relay opening the line thus preventing the call from taking place.
I don't know how to connect the pins of the Omron relay to the TIP or RING lines (Any line should work right?...because all i am tryin to do is break the connection). I attached a document entitled "activating Electrical Device.pdf" which shows the schematic of the Line realy connected to L2 (which is either the TIP or RING line as i gather from reading the article) I bought the Omron relay to try to perform this action but don't know how to connect it...This realy could work right?...I attached the datasheet as well.
Please tell me what pins i need to connect to the microcontroller and what pins need to connect to the telephone line please .
Regards.
