Hello I wish to control a 24V contactor from a Raspberry Pi with no HAT as I need access to pins for sensors and other parts of the project.
I want to use an optocoupler for safety. I am led to believe by my research as I will be switching a 240V 16Amp induction motor a contactor is better suited than a solid state relay.
I have found this schematic for driving a 12V relay so how would I adapt it to 24V contactor apart from changing the external power supply to 24V?
I plan on instructing an electrician to install the 240V side of the circuit.
This is the contactor I plan to use
I have researched posts on this forum but cant find an example with both 24 volts, a contactor and an optocoupler.
