#50628 - P89C51 relay interface |
I am using a P89C51RD2 and I ned to connect two relays to one of the ports. I guess that I should be using a solid state relay to isolate the coil of the electromechanical relay from the Microcontroller. Any suggestions as to what to use for a solid state relay? Do I need any chokes or filters as well as the relay? Do I need a resistor in parallal with the solid state relay for a drain.
I want to use a Sanyou DSY2Y-S-205L relay. Coil is 5V 200mW. I am very new to these components, sorry if these are stupid questions but I am not familiar with this. Don |
