    Electromagnet analog control

    Not done yet, but here is a quick update. 1st method: Using the Drive made to run DC motors works well with the electromagnets. The PWM does the job fine. I just use the potentiometer of the drive to test the electromagnets in parallel under 0V-24VDC. I shouldn't see any issues using the 0-10V...

    Electromagnet analog control

    It does, Thanks for the help Keith. I ordered the SSR and I am sourcing the diode right now. DC driver ordered as well as option B. Sylvain.

    Electromagnet analog control

    Sorry, I should have been more clear. I was referring to a drive like this one: https://www.automationdirect.com/adc/Shopping/Catalog/Drives/DC_Drives/Low_Voltage_(%3C_50V)_Open_Frame/GSD1-48-10C it runs on a potentiometer but can also take 0-10V as input signal. Thx, Sylvain.

    Electromagnet analog control

    Thx Keith for you reply and info. Ok for PWM. You mentioned the SSR. The PLC doesn't have a PWM function per say but it can be done in the ladder in few rungs (time proportional control). What period would you recommend? 50ms? I'll get the SSR and wire a diode to protect from the inrush...

    Electromagnet analog control

    I need to control the force of 3 electromagnets wired in parallel to pick up steel discs that are piled up in a stack. Discs range from 4" to 42" in diameter of various thicknesses (0.075" to 0.25"). 1/2 lb to 85lbs. About 30 different format total. One stack is composed of only identical discs...
