The relay cable is used to control the battery charging process on machines with a built-in battery.
The relay cable for SaT video recording is switched into the 230VAC supply voltage of the charger. If the charger is installed with the supply voltage, the relay picks up. The battery charge can then be recorded with a data acquisition device.
It has a 3x1.5 mm² cable and C19/C20 plug and is therefore suitable for higher-power chargers.
