RIO-D4

Pharos RIO D4 4-Port DALI Controller Expansion

The Pharos RIO D4 (Remote DALI 4-Port) serves as an expansive remote I/O interface, offering a flexible and streamlined method to drive DALI light sources and ballasts using Pharos control systems.

Featuring four independent DALI ports, each unit handles both outgoing control signals and incoming DALI data. Every active port connects straight to a powered DALI bus, while the RIO D4 communicates with the central Pharos controller across a standard Ethernet network.

DALI Control

Every port on the RIO D4 manages up to 64 DALI devices, complete with support for commissioning via native DALI discovery and configuration tools. Combine multiple RIO D4 units across a single Ethernet network to deliver flexible, distributed DALI management for larger installations.

Power-over-Ethernet

Operating as a Power-over-Ethernet (PoE) unit, the RIO D4 can be positioned wherever needed using a single cable to supply both operational power and network data.

Installer Friendly

Built for fixed setups, it features user-friendly 5.08 mm (0.200″) plug-in rising-clamp terminal blocks, a space-saving plastic housing, and quick DIN-rail mounting. A built-in rotary wheel allows for easy hardware addressing and quick activation of test modes.

DALI Commands

The RIO D4 seamlessly integrates with third-party DALI setups by monitoring incoming DALI traffic from external controllers or wall panels to trigger lighting actions on your Pharos system.

Network Connectivity

Communicates smoothly with Pharos controllers across a standard Ethernet network using industry-standard protocols.

Reliable

Durable, solid-state construction ensures continuous, hassle-free 24/7 performance without moving parts.

Scalable

Effortlessly link multiple remote units on the same network infrastructure to tailor the system size to your exact project needs (maximum capacity determined by the primary controller).
