    i have bought a general purpose Omron MK3P-I 28V DC plug in relay for a project.The relay is going reverse polarity to to reverse a 12V DC,5.5A permanent magnet linear actuator hourly.
    When inductive loads like linear actuators get switched off,there is high current generated by which is about 8 times its rated current;which can 'roast' the relay.There is ver little information online about how to protection diodes effectively in applications involving polarity reversal.
    I have read that wiring one diode in both wires between the relay and the actuator can take care of the situation.Or not?
    Any suggestions?

    This same EXACTLY worded the same post is floating around in another forum with a different poster name. Look there.
