<R42> Each power-regulating device (speed controller or relay module) shall control one and only one electrical load (motor, actuator or compressor).
Exception: Multiple low-load, pneumatic solenoid valves may be connected to a single relay module. This would allow one relay module to drive multiple pneumatic actions. No other electrical load can be connected to a relay module used in this manner.
From my understanding, a spike can control 2 circuits only if they are low-load, pneumatic solenoid valves. So you cannot control 2 different LED's (although I'm sure the current requirement is comparable).
If someone here disagrees, please let me know. Right now we have 3 relays for this purpose and I would not mind going down to 2!
