I’ve got a well pump (240VAC, probably draws around 8 amps) that I bought a relay for (Panasonic SP2-DC5V) and a raspberry pi zero w to trigger the relay.
The amperage/voltage required for the relay coil (60 mA/5V) don’t match the pi, so I grabbed a Sparkfun logic level converter (https://www.sparkfun.com/products/12009) as well. I’m now realizing that this converter itself won’t actually work, because it can’t supply 60mA to the coil (due to the 10kOhm pullups). Should I be looking for a transistor/resistor pairing to drive the coil based on the pi’s gpio?
You can use a transistor driver, switching a 5V power supply for the relay coil. Don’t forget the inductive kick diode across the relay coil. Typical circuit for a logic level (required) MOSFET shown below. A motor driver module will work too.
