Isolation relays are required in parallel applications.
The reason parallel applications need isolation relays is that the
motor uses two sets of windings, one for each direction. When
one is energized to turn the actuator in a specific direction a
voltage is generated in the other due to the magnetic field created
from the first. It’s called back EMF.
This is OK with one actuator because the voltage generated in the
second winding isn’t connected to anything so there is no flow;
it has no magnetic effect on the motor.
On parallel applications without isolation, this EMF voltage
energizes the winding it is connected to on the other actuators in
the system, the actuators are then trying to turn in both directions
at once. The EMF voltage is always less than the supply voltage
due to the resistance of the windings, so while the actuator still
turns in the commanded direction, the drag from the other
reduces the torque output and causes overheating.
