Hello. i am a student right now studying communication engineering, and has been assigned this task of setting up a security camera.
my current task is to design and develope a Digital I/O with isolation...for the RTV-24 which is this thing over here.
http://www.adlinktech.com/PD/web/PD_detail.php?pid=247
I have to use a Opto coupler-Circuit for the Input and a DC relay circuit for the output to the D-connector.
The opto-coupler has to be able to withstand +5V-24V at the least.
The inductive coil is 5VDC, contacts are 24VDC. It is a 5VDC relay.
How should i go about doing this project...such as finding the resistor values, and such pardon me for being such a noob on this...i have not been taught any of it before.
