DRF Valve Controller

When the feedback (channel 2 input 5.5V) is
greater than the command (channel 1 input
1.3V), DRF outputs 0A to Channel 1.

Channel 2 does not have an output.

When the feedback (channel 2 input 5.5V) is
less than the command (channel 1 input
7.2V), DRF outputs 0.74A to Channel 1.

Channel 2 does not have an output.
