I am designing a panel where I really do not need 110VAC power. I have incoming 230VAC and I have 24 VDC. It is somewhat difficult to find contactors with 24VDC coils. I also have a future need to drive some coolant solenoid valves. As much as I hate higher voltages, I am leaning towards using a MCR contactor with a 230VAC coil. I would spec coolant valves with 230VAC coils also. Is this likely to cause a problem?
I have found that putting large coils on my 24VDC circuits to be problematic. The 24VDC is powering several microprocessor based devices,
and I have seen spikes and noise from the contactors reset the electronic devices. It makes sense to me to keep them on separate circuits.
Thanks,
