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.

USE
Connecting a 230V mains voltage to the input allows you to switch 4 mains voltage consumers like lighting, a
pump, an electric heater, electric valves, etc.
Connecting a 12V low voltage to the input allows you to switch 4 low-voltage consumers like low-voltage lighting,
LED strips, low-voltage LED spots, etc.
The module is integrated into the Velbus system and controlled through the VMB4PD control panel or by means
of pushbuttons connected to a VMB8PB pushbutton interface, VMB6IN or any other relay module.
To interconnect the Velbus modules it is recommended to use a twisted-pair cable (EIB 2x2x0.8mm², UTP
4x2x0.51mm² - CAT5 or equivalent).
Make sure to use a heavy-gauge wire (0.5mm
2
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).
Mains Voltage Connection Diagram
A single-pole load (e.g. lighting) can be connected directly to the output.
Maximum total current consumption: 16A
VMB4RYLD 4-channel relay module user manual - version 1 9
A double-pole load (e.g. mains outlet) requires an extra double-pole relay.
A triple-pole load (e.g. water heater) requires a quadrupole relay.

Low-Voltage Connection Diagram
The module is also suitable for controlling 12V or 24V LED bulbs or strips. The input will then be con nected to a
low-voltage power supply (12V or 24V). Choose a power supply which can deliver the require d consumption while
the total consumption does not exceed 12A.

Termination
Remove the cover.
Generally, only 2 ‘TERM’ terminators must be used in a complete Velbus
Termination
®
installation. Usually, this will be on one
module inside the distribution box and on the module which is physically located furthest from the distribution box.
On all other modules, the terminator must be removed.
Remark:
In case of a wiring with multiple branches, only place a termination into a single module in the distribution box and
in the control panel which is the farthest from the distribution box. When communication problems occur, you can
place an extra termination on another branch. It is highly recommended to limit the number of terminations as too
large a number may overload the bus.

Configuration
This relay module can only be configured through the Velbuslink software.
The address, behaviour and control functions can be configured manually.
Address
Each module in the Velbus connection must have a unique address.
Configure the address through the software.
Relay Contact Behaviour
The relay contact will behave as an NO contact (no voltage on the outputs at no load).
With the software, this behaviour can be modified to an NO contact: at no load (when the indication LED does not
light) the relay contact will be closed and the output will present a voltage. Make sure however this occurs when
the relay module is live.
Control Functions
The relay module is controlled through pushbuttons connected to the Velbus system via a pushbutton interface or
control panel.
You may assign up to 39 different pushbuttons. Each pushbutton may activate a different function.
