#97347 - no need to mention it
Responding to: ???'s previous message
If your 'standard' relay is DC, we put a diode across the coil to soak up this spike
no need to mention it, if there is no diode, after one turn on there is no driver. At least i have neve seen a transistor surviving driving a relay coil without the diode.
