Quoting Dan Novy <[email protected]>: > If you hit a 5v latching relay with 9v, will it damage it? > > -- > Dan Novy > Technical Supervisor > Flash Film Works If you mean the coil, 9V is 180% of 5V rated coil voltage. The issue is the total power dissipated in the coil. If you only pulse the relay at a very low duty cycle at room temp, it won't ever build up enough heat to damage it. Drive it this way 100% duty cycle, and at a high ambient temp, then yes, you will probably overheat and damage it. Regards Bruce
