Application Notes

EAP-031081

In ratio control, I need to change the ratio manually at the front of the panel.

Install a potentiometer with ratio scale on the panel. Connect its output to our Potentiometer Transmitter model PMS and then its output to Math Function Module model JF. This module multiplies the reference signal F1 with the ratio signal K to get the target value F2. With this system, you can change the ratio K manually with a potentiometer. (Refer to Figure below.)
