Controller with analog current input (4-20mA) 2 Years, 3 Months ago
We're interested in dc motor controllers for our sawmills. We need single or double axis controller for 12VDC motors, each 60-80A. We know that you have in offer such controllers, but we need analog current input 4-20mA, not voltage 0-5V. Can you make such controller?

All that would be needed is a 100 ohm resistor at the controller and this will convert the 4-20 ma into a 0.4v to 2.0v command voltage. The analog input range on our controller can be configured to interpret these values as the min and max commands. The hdc2450 dual ch brushed dc and the vbl1650 single ch brushed dc controllers can operate that way and will handle your current requirements.
