Votronic D+ Simulator PRO 3067 – D+ Signal Simulation for EURO-6 Vehicles
The Votronic D+ Simulator PRO 3067 is an electronic module that simulates the missing D+ signal from the alternator in EURO-6 vehicles. It ensures that battery chargers or split relays for the auxiliary battery operate correctly.
Reliably simulates the D+ signal, enabling the use of modern chargers even without a factory D+ wire.
Compatible with EURO-6 vehicles – automatic engine run detection and time-delayed signal release.
Compact module with simple installation – plug-and-play saves time and workshop costs.
Enhances onboard electric system reliability and protects the starter battery from deep discharge.
What sets the Votronic D+ Simulator PRO 3067 apart
Unlike basic D+ replicators, the PRO 3067 uses intelligent engine run detection. It activates the simulated D+ signal only after a short delay – exactly like a real alternator signal. This avoids switching spikes and protects connected devices.
Ideal for…
Campervan and motorhome owners who want to upgrade or retrofit their vehicle. Especially suitable for owners of EURO-6 diesel or petrol vehicles where the manufacturer omitted a separate D+ line. Also for mechanics and vehicle electrical installers.
How to use the Votronic D+ Simulator PRO 3067
Connect the module according to the wiring diagram between the alternator (D+ terminal) and the charger or split relay. After engine start, the simulator detects the voltage and releases the D+ signal after approx. 30 seconds. An illustrated instruction manual is included.
Votronic is a German manufacturer of high-quality charging and onboard electronics for mobile use. The company specializes in battery chargers, solar regulators, voltage converters, and D+ simulators. Votronic products are widely used in the caravanning and marine sectors and are known for their reliability.
A D+ simulator reproduces the alternator signal (D+ terminal). It is needed when the vehicle – especially modern EURO-6 models – does not provide a separate D+ signal for auxiliary battery charging. The simulator activates the charger or split relay once the engine is running.
The PRO 3067 is designed for EURO-6 vehicles. It works with 12V electrical systems and is suitable for diesel and petrol engines that lack a factory D+ line. Please check compatibility with your vehicle model before purchase.
The module weighs 119 g and measures only a few centimeters. It requires a 12V operating voltage and releases the D+ signal after an adjustable delay of about 30 seconds. Connection is via three wires (D+, ground, D+ output).
The package includes the D+ Simulator PRO 3067, a connection cable, mounting hardware, and a multilingual user manual with wiring diagram.
Installation is straightforward by connecting the cables according to the included diagram. The module is small and can be mounted in the engine bay or under the dashboard. An LED confirms operation after engine start.
