    If anyone can help, I have a linear actuator as below
    -24 V DC permanent magnet motor
    - Thrust up to 6000 N in push and up to 4000 N in pull
    -Duty cycle: Max 10% or 2 minutes continuous use
    followed by 18 minutes not in use
    -FLC 3.9A at 24v DC

    The application uses the actuator to open and close a shut off gate in a dust extraction system. I need to be able to use a current sensing device which can be cliped to the load side of a particular machine which when energised will open the gate, and once de-energised it will close the gate. Being a DC actuator the poles need to be reveresed when switching. I have simulated this using DPDT relays, but i need to be able to have somthing off the shelf, as it becomes quite time consuming as far as labour goes when there are multiple gates. If anynoe knows a standard way or an easier way of dealing with this i would much appriciate the help.​

The relay with your 24VDC supply controls the actuator. This assumes the actuator has internal limit switches.
