Create A New AccountThe ETC R20AF Relay Module is a dual, plug-in mechanical relay assembly for use in both Sensor® + and Unison® Dimming Series modular dimmer rack enclosures. Each Relay Module provides two electrically held relays, in the same form factor as standard dimmer modules. This enables designers to mix and match dimmer and relays for control of diverse loads. Ideal for control of non-dimmable load types such as HID lamps. Standard Relay Modules provide cost-effective switching while Advanced Features Relay Modules enable dimmer-specific feedback of load circuit data while performing switching in AF-capable Sensor+ dimmer enclosures.
We offer free ground shipping on most items for orders $300 and over, $20 for flate rate ground shipping on orders from $150 to $299.99, and $14 flat rate ground shipping on most items for orders under $149.99. *paints, liquids, and large volume items like boom bases (very heavy) or fake snow (not heavy, but very large) may incur a shipping surcharge. Exclusion of items from Free and Flat Rate shipping is at ProAdv's discretion. Offer is currently limited to Lower 48 US States.
We ship to North American addresses. Note that there are restrictions on some products, and some products cannot be shipped to international destinations, or even certain states depending on the item and state or local laws.
Our full policy is in our Terms and Conditions page.Please Note: Due to unprecedented raw material and component shortages for finished goods throughout our industry, lead times for items that aren't currently in stock are longer than normal and cannot be guaranteed at present. Equipment needed by a firm date must be noted at time of order. While VLS cannot guarantee delivery by those dates, we will work with our suppliers to do everything possible to meet deadlines. We apologize for the inconvenience and appreciate your patience.
Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.
Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.
Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.
We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
