Alright, so tomorrow I'm doing 4 actuators on each door for a keyless entry system. My question is I am using the 451m relay pack by directed electronics, to give power to the actuators. Do you think I should be fine running all the actuators off one 451m? Or should I do one for the front doors and one for the back? Or possibly one for each door (I don't know if I have enough in my box).
Thank you

One module will be sufficient for what you are doing.
The relays in the modules are good for 30 amps and your four actuators should not be anywhere near that.

a 451M is 10A/20A

4 actuators where the linkage is nice and easy should draw about 16-20amps total but remember this draw is only for about 0.8secs. The UK build Civic 96-2000 and Honda CRVs use a relay motor wire interrupt circuit and I constantly use 451ms to drive these with no problems.

Cool Thanks. Second opinion is greatly appreciated.

A 451m is fused at 15 amps isn't it! As another kelly said it's capable of 20 amps on the normally open circuit, so you may have to replace that 15amp fuse with a 20 amp to accomadate those for actuators! Speaking from my limited experience, that fifteen amp fuse will only hold out for a while with those four actuators before it pops, twenty always does the trick!
