wiring a relay
hi does anybody have a diagram for a hella 30amp relay (the square black ones) it for a linear acuator which has 2 wires from it red and black,they say i need a 6 pole switch so i can reverse polarity any help would be great thanks darren
How are you going to operate the relays?
It's possible to do it with 2 Single Pole Double Throw relays. In those Black Hella style, typically sold as Changeover Relays.
Wire the actuator wires to the common terminals on both relays.
Wire a Negative to both Normally closed contacts, then wire a positive to both normally open contacts.
It will sit normally with negatives attached to both wires of the actuator.
Energise one relay it will switch one side to a positive and make the actuator operate, de-energise that relay and energise the other one it will then switch the other side to a positive which will make the polarity reversed.
I found this diagram on the net to save me drawing it. Which even has the terminal numbers for the square black changeover type relay.
Then it just comes down to selecting the right switch to operate it.

If God did not intend for us to eat animals, then why did he make them out of meat?
And if both trigger together, nothing disastrous happens.r0ck_m0nkey wrote:How are you going to operate the relays?
