MorningStar RD-1 Relay Driver with Auto GenStart Function This innovative versatile-application Morningstar Relay Driver is a highly flexible and fully programmable logic relay module, capable of switching appliances on/off or sending signals and generating alarms when a predefined event occurs. A truly versatile product, this relay driver can be used in a wide range of applications and scenarios, such as: Monitoring battery voltage: When the battery is full, excess solar energy can be directed to power a fridge or water heater. Monitoring battery voltage: When the battery is too low, the driver can start a generator or mains battery charger to top it up or disconnect any loads (low voltage disconnect). Performing staged low voltage disconnect: Ensures the most critical loads stay on for longer. In a wind power system: Diverts wind turbine power to a dump load when the battery is full. Enhancing wind turbine efficiency: Routes output through a voltage boost converter at low RPMs but uses the output directly at high RPMs. Activating cooling or battery fans based on temperature. Controlling motion sensors. Controlling water level pumps. Managing pressure release valves. Controlling space heating or cooling. The built-in GenStart function offers advanced generator control with up to three channels, programmed to start a generator based on specific events. While it functions as a standard on/off dry contact generator control for small, simple generators, in this mode, the relay driver can also manage advanced generators with a 3-wire control system. In such setups, the driver generates various signals required by the generator, such as: Run, Pre-crank (Pre-Heat), Crank (Momentary Run), Load, Stop, etc., each with different durations, sequences, and delays relative to each other.
