Information About GRX-TVI
The GRX-TVI is a high-performance Ten Volt Interface from Lutron engineered for integration with Grafik Eye and HomeWorks systems. It provides Class 2 isolated 0–10 V- control for current-sourcing ballasts and drivers, using universal phase input (100–277 V~). This device is compatible with a wide range of wallbox dimmers and RPM control modules to switch up to 16 A of lighting or motor loads. Built with a plenum-rated Type 1 enclosure, it enables reliable dimming and switching in residential and commercial installations.
Key Features:
- Universal Phase Input: Accepts forward, reverse, and center phase 100–277 V~ signals.
- Class 2 0–10 V Output: Provides isolated low-voltage dimming control compliant with EN60929 / IEC929.
- High Load Switching: Handles up to 16 A of capacitive, LED, fluorescent, or incandescent loads.
- Motor Switching Capability: Supports motors up to 1/2 HP at 120 V~ and 1½ HP at 277 V~.
- Multi-Zone Capacity: Connect up to five GRX-TVI units per control zone for expanded circuits.
- Plenum-Rated Enclosure: Suitable for environmental air spaces per NEC® and Canadian code.
- Independent Circuits: Control and load circuits operate independently and allow different phases.
- Robust Compatibility: Integrates with Grafik Eye, RPM panels, wallbox dimmers, and third-party drivers.
The GRX-TVI delivers the reliability and precision required for high-performance lighting and motor control applications.
