After the chart in R51, it says:
*Multiple low-load, pneumatic solenoid valves, electric solenoids or CUSTOM CIRCUITS may be connected to a single relay module. This would allow one (1) relay module to drive multiple pneumatic actions or multiple CUSTOM CIRCUITS. No other electrical load can be connected to a relay module used in this manner.


So as I see it, you can use multiple solenoids on one Spike relay, but the asterisk is not included on the solenoid breakout.

So if it is a 12v solenoid you are okay, if it is 24v you are out of luck.
