ETC R20 Relay Module 20A Dual-Circuit DRd Control

The ETC R20 is a dual-circuit relay module designed for use in Unison DRd enclosures where dependable switched power is required instead of phase dimming. Its high-density modular assembly supports efficient enclosure population, while the die-cast aluminum chassis and magnetic breaker design align with the demands of permanent architectural and entertainment lighting systems. For facilities managing non-dim loads, powered effects, or controlled branch circuits, the R20 provides a clean fit within the DRd ecosystem.

This module is suited to applications that call for straightforward on/off control across two circuits in a single slot. Common use cases include moving lights, fog machines, powered effects, and other loads that should not be dimmed. ETC also incorporates temperature sensing and a sealed power device assembly to support long-term serviceability in installed environments. Because it is keyed for proper enclosure placement and listed for use in Unison DRd dimming enclosures, the R20 is a practical choice for integrators and specifiers standardizing around ETC power control infrastructure.
