The PSC-ZAD-I-XXX-BLE-CB is a compact DALI D4i wireless sensor-controller designed for intelligent, fixture-integrated lighting control. Combining motion sensing, optional ambient light detection, and wireless communication, it enables responsive and energy-efficient control of DALI drivers without the need for gateways or wired control systems.

The device integrates directly into a luminaire via a Zhaga Book 18 quick-connect receptacle, making it ideal for modern, connected lighting designs. Using Bluetooth® mesh technology, the controller wirelessly communicates with the lighting network while converting mesh commands into DALI-compatible control for smooth dimming, zoning, and trim adjustment.

An integrated PIR motion sensor provides reliable occupancy detection, while selected variants include a built-in photosensor for daylight-based control. With an IP65-rated housing, the PSC-ZAD-I range is suitable for both indoor and outdoor environments.

Flexible power options allow operation via either 24V DC auxiliary power or DALI bus power, depending on the model. Configuration, commissioning, and ongoing adjustments are handled through a mobile app, offering real-time feedback, scheduling, and system optimisation without requiring internet access.
