The diode circuit you have posted is standard for inductive loads, so it should work ok. At 90mA you are either going to pop the PIC pin or limit the drive to the relay. Last edited: Jun 19, 2011

B bigal_scorpio Active Member Jun 19, 2011 #23 Hi Guys, Well I just found some 2 coil relays in my box! Guess that solves my problem and I can now drive them with transistors too! Thanks for all the help guys. Al
