  • What type relay are these?

    I have 4 linear actuators and they came with a diagram and i don't know what type of relay they are.

    I have lots of the normal relays so if anyone can help using these relay in place of the above i would be very thankful.

    Looks to me like the relays are basically just switching pos and neg at the same time. Basically one is functioning in one polarity and the other is reversing the polarity to move the actuator the other way.

    Just use two normal relays in place of each of the shown. Have one go to power and the other go to ground. Do the same thing with the other relay, just opposite.

    Sorry I can't sit here and draw out a diagram for it right now, but if you don't get my drift reply to this and if i don't get to it in a while shoot me a PM to remind me and I'll try to get to it as soon as I can.

      Its double pole double throw.

      Its basically 2 switches in the same package, the switches are controlled by the single coil at the same time. Like above you can use 2 normal car relays by connecting the 2 coils together.

      Here is your usual car relay >

        OK i still don't understand what wire goes where on the normal car relay. I should have posted the other picture that shows the limit switches.

          First thing you need to make sure the relays you have have 5 pins on them... many only have 4. In order for them to work properly in this situation you much have 5 pin relays.

          I don't have time tonight to make a diagram.
          Pin 85 - coil +
          Pin 86 - coil -
          Pin 30 - power or ground source (depending on what you need to switch
          Pin 87a -connected to pin 30 when the coil is not charged
          Pin 87 - connected to pin 30 when coil is charged
