About this product
The Sonoff DR is an adapter tray that turns a standalone Sonoff module into a DIN-rail-mountable device. The module is fastened with the four supplied M3 screws, which drop straight into Sonoff's original screw holes, so you do not need to drill anything.<br><br>The blue clip works on a push-pull principle: push to lock the tray onto the DIN rail and pull to release it, all without tools. The body is made of flame-retardant ABS (V0 class) and measures 122 × 54 × 14 mm. The DIN rail itself is not included in the box.

Frequently asked questions
Which Sonoff modules fit the DR tray?
The DR is meant for classic Sonoff housings such as BASICR2, RFR2 and DUALR2; check that your module has the matching mounting holes.Is the DIN rail included?
No, the standard 35 mm DIN rail is not in the box; if your panel does not already have one, you need to buy it separately.Do I need tools to install it?
Not to clip it onto the rail — the push-pull clip presses on by hand. To fasten the module to the tray you use a screwdriver and the four supplied M3 screws.What is the tray made of?
Flame-retardant ABS in the V0 class, suitable for mounting in an electrical panel next to live connections.How much space does it take on the rail?
Its 54 mm width occupies about 3 standard DIN module slots; leave that space free in the panel before mounting.Can I remove the module later without damaging it?
Yes, the push-pull clip lets you take the tray off the rail with no effort, and the module stays intact for reuse.Does the DR tray have any electronics or wiring?
No, it is a passive mounting accessory — no circuitry, power or protocol; it only mechanically holds the module on the rail.
