If you mean this MTH occupancy sensor that plugs into Realtrax, there is a relay inside.
From the thread I referenced earlier, when using two of these sensors, you still need an external relay to arbitrate any conflicts (when one sensor says to raise gates while the other says to lower gates).

I called MTH today and they seemed to think the actuaters would work and did not mention the need for additional diodes or relays.
Ask them for a diagram. Nothing is so easy as the job you imagine someone else doing.
