VMB4DC 4-channel dimmer controller module user manual – version 3 9

USE

The dimmer controller module is to be used with neon lighting equipped with a dimmable electronic starter using a

1-10V control signal, or with a DC-controlled power dimmer.

The module is entirely integrated into the Velbus system and controlled through the VMB4PD control panel or

through pushbuttons connected to a VMB8PB pushbutton interface.

To interconnect the Velbus modules it is recommended to use a twisted-pair cable (EIB 2x2x0.8mm2, UTP

8x0.51mm - CAT5 or equivalent).

Make sure to use a heavy-gauge wire (0.5mm

or more) in case of a multiple module connection (>10 modules) or

with log connections (>50m).

Connect the bus to the module (mind the polarity).

Connection diagram with dimmable neon lighting

The neon lighting must be equipped with a dimmable electronic ballast using a 1-10V control signal.

You can connect several neon tubes to 1 channel.

The Velbuslink program links every dim channel with a relay channel in momentary control so the voltage of the

neon tube drops at 0V in order to switch the lighting completely off.
