2 VMB4DC 4-channel dimmer controller module user manual – version 3
DESCRIPTION
The module features four 0/1 to 10V outputs. Each output can accept one or more DC-controlled power dimmers
so as to dim lar ge groups of bulbs simultaneously.
The module also allows you to dim neon lighting equipped with a dimmable electronic starter with 1-10V control
input.
Controlling DC-controlled LED dimmers allows also an attractive ambient lighting.
Each channel can memorize several dimming functions and preset ambiances.
CHARACTERISTICS
Use:
• suitable for controlling DC-controlled power dimmers with 0/1-10V control input
• suitable for controlling DC-controlled LED dimmers with 0/1-10V control input
• suitable for dimming neon lighting equipped with a dimmable electronic starter with 1-10V control input
Outputs:
• 4 outputs with common (-) connection
• output voltage: 0 to 10V or 1 to 10V (adjus table per outpu t)
• max. output current: 10mA per output
• the output is protected against short-circuits and overvoltage
• galvanic separation between the output voltage and the Velbus power supply (3000VDC isolation)
LED indications:
• status indication for all 4 channels
o continuously lit: selected dimming level achieved
o slow blinking: timer running
o fast blinking: changing dimming level
o two short blinks: communication error
• power voltage present
• data reception and transfer over the Velbus
• status notification of the dimmer to the control modules
Module power supply:
• required power voltage: 12...18VDC
• consumption in stand-by: 45mA
• max. consumption: 100mA
Dimensions:
• standard DIN-rail housing: 2 modules
• L x W x H: 90 x 36 x 58mm
Configuration:
• only configurable via the Velbus PC interface (VMB1USB, VMB1RS or VMBRSUSB) and the Velbuslink
software
• addressing through software (up to 250 addresses)
• storage spac e for 37 different pushbuttons and t he ir function
• multiple functions and timer settings are configurable through software
• learned pushbuttons are saved in case of a power failure
Control:
• local control on the mod ule (on/off at short press, dimming at long press)
• through Velbus commands or pushbuttons connected to the Velbus system
• multiple control functions
o momentary
o off or slow off
o on or slow on
o on/off or slow on/off
o timer (start/stop, restartable or non-restartable)
o dimming (more or less intensity)
o more intensity
o less intensity
o moods
