Hey guys was curious if the two relay setup for one actuator is enough to power 3 more actuators. I've done a search so far no luck. Will I need 2 relays for each actuator?? Appreciate the help in advance.

I purchased the DEI 451M, could i possibly use this to power all 4 actuators?

Is up to the installer to test all wires with a DMM whenever possible.

Two relays wil be good enough to power all four actuators, yes. I've done it several times before. Just be sure to fuse it at 7.5 amps per actuator, which will be 30. Also, for the power and ground wiring to the relays, use no thinner than 14 guage.
