Controlling motor speed from ClickPLC Analog output

I have a KB Electronics KBAC-27D motor controller with start/stop switch and a potentiometer which controls the speed of the motor. I'd like to control the motor speed from my ClickPLC. The documentation of the motor says "To operate the drive from a remote potentiometer (5 k?), remove the white, orange, and violet potentiometer leads from Terminals P1, P2, and P3. The wires may be taped and left inside the drive. The potentiometer assembly may be removed if a watertight seal is used to cover the hole in the front cover. Wire the Main Speed Potentiometer to Terminals P1 (low side), P2 (wiper), and P3 (high side). " What is the best way to control this motor speed from a ClickPLC? Would the C0-04DA-2 work to provide the necessary analog output and if so what do I wire to P1,2,3? thanks

    Page 22 should tell you what you want. Look for a section labeled Voltage Following Connection.

    As mentioned in the KB manual, use a signal isolator. Something like this https://www.automationdirect.com/adc...er_Input/FC-33

    With the FC-33, you can select the input voltage range and the output voltage range by dipswitches on the side, so you could use the 10V analog out on the C0-04DA-2.

    Do you already have a CLICK CPU? you can get analog out (0-5V) on a CPU.
