But can the LED survive, in case the relay is activated/deactivated many times in a short time? A LED is normally not a powerful diode. I'm not sure either, but I'll say this, the diode MUST have a series limiting resistor inside the relay, that will limit its ability to clamp to the coil voltage, so you can still have HF nasties, with admiteddly only coilo voltage maximum amplitude, but whatever frequency they want to be |
