As one of the most popular forms of lighting control, relay controllers can have the greatest impact in terms of energy management and lighting control. The Philips Dynalite solution provides a range of relay controllers with a variety of circuit numbers and sizes to work individually or as part of a system, thus fulfilling any project requirement. Each device can store over 170 presets, allowing the recall of complex switching logic from simple network messages. As the required preset scenarios are stored within each relay device, the commissioning process and network messages are simplified.
