1. A control device comprising:
- a control module configured to provide a driving signal that is adapted for modifying a control voltage on a 0-10 volt control bus;
a processing module configured to determine a duty cycle of the driving signal, wherein the processing module is configured to receive power via the 0-10 volt control bus and has a power requirement less than or equal to a power available via the 0-10 volt control bus; and
an interface configured to convert signals received from an external control device to a voltage level usable by the processing module.

Abstract
A lighting control device can include a control module and a processing module. The control module can provide a driving signal. The driving signal can modify a control voltage on a control interface. The control voltage can control a controllable ballast or driver. The processing module can determine a duty cycle of the driving signal. The control module and the processing module can receive power via the control interface and a power supply on the control device.
