We are building a simulator for a control system on a large construction machine. Trying to emulate the steering feed back by moving a sensor with a motor in place of the steering cylinder. The cylinder is controlled by a proportional valve driven by a Plus 1 controller.
The controller has 2 outputs that drive the coils of the valve, we need to use those 2 out puts to drive a geared motor to turn the sensor.
I need to make a circuit that will let us drive the motor with out back feeding the controller.
Controller runs on 12-24 VDC there is also a 4.5 VDC supply available. In experimenting with the motor-controller we found it easily drives the motor one way with each output signal.
Any ideas?
