Thanks! I figured that 15mA would not work for everything. I still need to figure out what the solenoid load will be.

Thank you for your help.
I would certainly have ordered from emcPT if I knew that my order was not going out as promised.
And yes, I'm in Scandinavia, Norway to be more exact. Which means it will probably sit waiting for some days in customs clearance (actually VAT) adding to the shipping time.
@Jake: A low voltage relay load will ussually be less than 50mA. A solenoid could be more. If you find the specs on yours, that is usually a parameter given there. Remember to put in a flyback diode on your contactor if DC. A resistor/capacitor snubber if AC. And place that on your relay/solenoid. Not at the driver board.

Yes, I made these for enabling servo amps and VFDs. Crydom does make DC SSRs, but they are REALLY expensive, several times more than AC types.
Thanks guys! Figuring out how many relays I need and which ones is on my list of stuff to do this weekend, so I can order them next week, if not tomorrow. Machine has air and power to it now, and its getting cleaner.
I'm using Pico systems (pwm servo) on my 5axis machine (home built) and received also very very good support, which means a lot to me as I'm inexperienced in electronics.
