IN4001, IN4003 diode or equivalent, observe polarity.
Explanation: The diode allows the positive (+) signal to
pass through it and does not allow a higher level posi-
tive signal to back feed to the other controller. Only the
highest controller signal is seen by the actuator. There
is a .7 VDC voltage loss across the diode. This makes
the actual voltage range 2.7 to 10.7 VDC.
