Hi
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?
