jbanik 0 Posted March 31, 2015 Share Posted March 31, 2015 Hi, I am trying to operate a 3V relay (from OMRON) using MSP430G2553. The relay is a SPDT one, with 6 PINs. I am not quite sure how to wire a6 PIN relay (I have some experience with 5 PIN SPDT relay), and I cannot find much information in the internet. I was also told that, for driving a 3V relay, I would not require transistor + diode combination. For your information, the relay has a rated coil current of 50 mA. Can anyone help me on understanding the wiring structure of the relay? How to interface it with MSP430? Also, is it true that, I can operate the 3V relay without separate transistor + diode combination? I do not have much experience in microcontroller, particularly in MSP430 platform. Any suggestion is welcome. Thank you in advance for your support. Quote Link to post Share on other sites
