Note that in the event of power failure or if the enable relay is cut off, then the power supply for the actuator is
also cut off. This is because it will otherwise continue to operate and the module is supplied with power via the
freewheeling diode, which can result in damage. It is therefore recommended to provide power to low-side outputs
via a high-side output of the same option board.
