You've been waiting for them to secure and professionalize your installations in the electrical panel: the new generation of our DIN Rail (DRB) boxes has arrived!
After more than 5 years of faithful service, our unique reference DRB-2-2-00 (V2) is retiring. It is replaced not by one, but by two new V3 models: a "Standard" version and a "Power" version.
Why this change? What are the differences? And most importantly, how do you adapt your wiring? We explain everything in this article.
Why a new DRB V3 range?
The world of connected buildings is evolving, and so are our modules. Our latest modules offer enhanced performance, capable of handling higher power levels.
Our previous V2 enclosure, while very versatile, no longer perfectly met the thermal requirements of today's high loads. To guarantee maximum safety and durability, particularly for withstanding a 14A resistive load in a 40°C environment, we decided to specialize our boxes.
That is why the DRB V3 range is now split into two distinct versions.
1. The "Standard" DIN Rail Box (DRB-1-3-00)
This box is designed for standard installations where NodOn modules do not need to withstand very high electrical loads. It is the ideal box for lighting, roller shutters, or dry contacts.
Main features:
- Maximum intensity: 6 A
- Usage: Lighting, openings, dry contact, etc.
- Compatible modules:
- SIN-X-1-20 (1-channel multifunction modules)
- SIN-X-2-20 (2-channel ON/OFF lighting modules)
- SIN-X-RS-20 (Roller shutter modules)
- SIN-X-SM-21 (Consumption Measurement Modules)
- Operating temperature: -20°C to 40°C
- Dimensions: 82×66×25 mm
- Weight: 48 g
2. The "Power" DIN Rail Box (DRB-1-3-10)
This box was specifically developed for installations where the modules need to control significant loads or perform energy consumption measurements. Its internal architecture and PCB are optimized for improved temperature resistance.
Main features:
- Maximum intensity: 14 A
- Usage: Heating, water heater, measurement functions.
- Compatible modules:
- SIN-X-1-20 (1-channel multifunction modules)
- SIN-X-1-21 (Multifunction modules with metering)
- SIN-X-FP-21 (Pilot Wire Modules)
- Operating temperature: -20°C to 40°C
- Dimensions: 82×66×25 mm
- Weight: 48 g
Warning: Important change to the wiring (Pin Out)!
This is the most important point of this update. The wiring of these new V3 boxes is different from the old V2 version, and it also differs between the "Standard" version and the "Power" version.
Thermal optimization required revising the correspondence between the terminals of the inserted module and the output terminals of the DIN rail box. Simply plugging them in "on the other side" is no longer sufficient!
The special case of the SIN-X-1-20 module
The SIN-X-1-20 module is the only one compatible with both versions of the box, but its use changes radically depending on the box chosen:
- In the "Standard" box (DRB-1-3-00): It is used for its functionalities of dry contact (potential free) at the output of terminals 4 and 5 of the DRB.
- In the "Power" box (DRB-1-3-10): It can be used either as a live output (shunt to be made between terminals 1 and 2 of the DRB) to power products, or as a dry contact (potential-free) at the output of terminals 1 and 4 of the DRB.
Correspondence diagrams
It is imperative to refer to the wiring diagrams specific to each box before any installation.

No need to panic: new stickers are included!
We are aware that this change in mappings may be confusing during installation if you have previously used the old DRB.
To make things easier for you and avoid mistakes, we now provide a new set of 5 sticker sheets in each box of DRB V3 .
These stickers should be affixed directly to your SIN modules before inserting them into the enclosure. They visually indicate the new terminal mapping (C, N, L, switch inputs) adapted to the box you are using.
In summary
The arrival of the DRB V3 range marks a significant step forward in the reliability of your connected electrical panel installations. By choosing the appropriate box (Standard for general use, Power for heating and measurement), you guarantee optimal and secure performance.
Just don't forget to double-check the new wiring diagrams and use the stickers provided!
