VMB4RYLD 4-channel relay module user manual - version 1 3
DESCRIPTION
This relay module is suited for switching on or off the lighting in the living room, the garden fountain, the mains
outlets in the children’s room, and many more.
In order to limit the wiring in the switchboard cabinet, this module features a mains voltage input and four voltage
outputs to which the consumer can be connected directly.
This is only suited for use in a Velbus system.
Multiple functions, e.g. switching on/off timers, are to be programmed via the Velbuslink software.
CHARACTERISTICS
Use:
• suitable for switching on/off mains-powered lighting or consumers
• connection of a low voltage (e.g. 12V) instead of a high mains voltage to the voltage input allows the
switching of up to 4 low-voltage consumers (e.g. 12V light bulbs)
• only suitable for use in a Velbus installation
Outputs:
• 4 voltage outputs with common N connection
• single-pole NO relay contact
• relay contact debounce
• switching capacity:
o 16A @ 230VAC input voltage
o 12A @ 30VDC input voltage
o allowed switch-on current up to 80A (lamp switch-on current)
• Total allowed consumption of the 4 channels:
o 16A @ 230VAC
o 12A @ 30VDC
• each relay channel may be inverted in order to simulate an NC contact
• 1 extra virtual channel
LED indications:
• status indication for all 4 channels
o continuously lit: relay switched on
o slow blinking: timer 1 running
o fast blinking: timer 2 running
o two short blinks: communication error
• power voltage present
• data reception and transfer over the Velbus
• status notification of the relay channels to the control modules
Module power supply:
• required power voltage: 12...18VDC
• consumption in stand-by: 30mA
• max. consumption: 250mA
Dimensions:
• standard DIN-rail housing: 4 modules
• L x W x H: 90 x 71 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 space for 39 different pushbuttons and their function
• multiple functions and timer settings are configurable through software
• learned pushbuttons are saved in case of a power failure
Control:
• local on/off control on the module
• no direct pushbutton connections
• through Velbus commands or pushbuttons connected to the Velbus system
