AC and DC relays

I purchased the advanced kit and am building it as a three phase unit. I am using the existing 40A two pole relay with the existing 12v DC activation for same. I have purchased a second two pole relay to switch the other two phases. This has a 240V coil. Can I run it off the AC relay connection? In other words, are the AC and DC relay outputs both activated at the same time by the code? I assume I could alternatively drive the second relay from the 240V of the first relay.

Which is preferable?

Hi Dave,

Both the AC and DC relay outputs are switched regardless of the relay type. The best solution would be a single 4 pole relay driven off the AC_Relay. The 2 relay solution should work, we would drive off AC_Relay as there would be a delay if you went off the output of the first relay.
