NEW ETC R20AF Dual 20A Relay Module, Advanced Features

Please note that the current lead time for this item is 3-5 business days.

The NEW ETC R20AF Dual 20A Relay Module is a dual, plug-in mechanical relay assembly designed for Sensor+ and Unison Dimming Series modular dimmer rack enclosures. Each module provides two electrically held relays in the same form factor as standard dimmer modules, allowing designers to mix and match dimmers and relays within the same rack to control diverse load types. It is ideal for switching non-dimmable loads such as HID lamps, where on/off control is required instead of dimming.

Compatible Systems

Built for use in both Sensor+ and Unison Dimming Series modular dimmer rack enclosures. Standard relay modules provide cost-effective switching, while this Advanced Features relay module enables dimmer-specific feedback of load circuit data while performing switching in AF-capable Sensor+ dimmer enclosures.

Advanced Features Feedback and Diagnostics

In supported enclosures, the R20AF can report circuit conditions using Advanced Features error messages, including: “Load dropped below recorded value,” “Load increased over recorded value,” “SCR failed on/off,” “Circuit breaker tripped,” “Dimmer module removed,” and “Dimmer load absent.” This feedback helps technicians identify changes in connected loads and common fault conditions faster during commissioning and service.
