USE
The relay module features 4 non-voltage NO contacts wich allow you to switch mains-voltage (230V) and low-
voltage (12 or 24V) consumers.
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 (0.5mm2or 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.

10 VMB4RYNO 4-channel relay module user manual - version 1
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.

VMB4RYNO 4-channel relay module user manual - version 1 11
Low-Voltage Connection Diagram
The module is also suitable for controlling 12V or 24V LED bulbs or strips. The input will then be connected to a
low-voltage power supply (12V or 24V). Choose a power supply which can deliver the required 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®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.
Function Description
1 Momentary The relay remains switched on as long as the pushbutton is
pressed.
2 Off The relay is switched off.
In order to create an “all off” function, the same pushbutton of all
relay channels will be configured as an off function.
3 Off with timers disabled The relay is switched off and the timers cannot be restarted.
4 Off with timers disabled at
short press A short press of the pushbutton switches off the relay but the
timers cannot be restarted.
A long press of the pushbutton switches off the relay and the
timers remain enabled.
5 Off with timers disabled at long
press A short press of the pushbutton switches off the relay and the
timers remain enabled.
A long press of the pushbutton switches off the relay but the
timers cannot be restarted.
6 On The relay is switched on.
May be used in a control panel with weekly program to switch on
an output at a certain point in time.
7 On with timers disabled The relay is switched on and the timers cannot be restarted.
When a PIR detector is triggered, the driveway lighting will switch
on for 10 minutes.
A pushbutton with the “On with timers disabled” function allows to
switch on the driveway lighting continuously without the PIR
detector having an influence on the action.
8 On with timers disabled at
short press A short press of the pushbutton switches on the relay but the
timers cannot be restarted.
A long press of the pushbutton switches on the relay and the
timers remain enabled.
9 On with timers disabled at long
press A short press of the pushbutton switches on the relay and the
timers remain enabled.
A long press of the pushbutton switches on the relay but the
timers cannot be restarted.
10 Toggle Each press toggles the relay status (on/off).
Normal lighting control in a room.

14 VMB4RYNO 4-channel relay module user manual - version 1
11 Toggle with timers disabled Each press toggles the relay status (on/off).
The timers cannot be started when the relay is switched on.
A PIR detector will switch on the driveway lighting; this lighting
can switched on/off with a pushbutton. A driveway lighting
switched on through the pushbutton will not be affected by the PIR
detector.
12 Toggle with timers disabled at
short press Each press toggles the relay status (on/off).
The timers cannot be started when the relay was switched on by a
short press.
13 Toggle with timers disabled at
long press Each press toggles the relay status (on/off).
The timers cannot be started when the relay was switched on by a
long press.
14 Start/stop timer A press of the pushbutton switches on the relay for a preset time.
A press of the pushbutton switches off the switched-on relay
immediately.
If desired, the short and long press delays can be set.
Control of the lighting in the attic. The lighting will automatically
switch off after a preset time.
15 Restartable timer A press of the pushbutton switches on the relay for a preset time.
A press of the pushbutton while the relay is switched on restarts
the timer.
If desired, the short and long press delays can be set.
This function is also called a staircase lighting timer.
16 Non retriggerable timer A press of the pushbutton switches on the relay for a preset time.
A press of the pushbutton while the relay is switched on has no
effect.
17 Trigger-on-release timer The relay status remains unchanged with the closing of the
switch.
The relay is switched on for a preset time with the opening of the
switch.
18 Delayed off at release The relay is switched off with the closing of the switch.
The relay remains switched on for a preset time with the opening
of the switch.
19 Delayed off at release only
when relay is on Nothing happens as long as the relay remains switched off. At the
release of the pushbutton, the switched-on relay will remain
switched on for a preset time.
20 Start/stop with delayed on/off Pressing the pushbutton will switch on the relay after the
expiration of the switch-on delay. The relay is switched off again
after expiration of the switch-off delay.
Pressing the pushbutton while the switch-on or switch-off delay is
running will annul the timer and switch off the relay.
21 Restartable delayed on/off Pressing the pushbutton will switch on the relay after the
expiration of the switch-on delay. The relay is switched off again
after expiration of the switch-off delay.
Pressing the pushbutton while the switch-on delay is running will
restart the switch-on delay.
22 Non restartable delayed on/off Pressing the pushbutton will switch on the relay after the
expiration of the switch-on delay. The relay is switched off again
after expiration of the switch-off delay.
Pressing the pushbutton while the switch-on or switch-off delay is
running does not affect the general status.
23 Start/stop interval timer Pressing the pushbutton will switch on the interval timer for a
preset time. The output is thus repeatedly open and closed. The
switch-on and switch-off delays can be set.
Pressing the pushbutton while the interval timer is running will
stop the interval timer.

A light sensor will keep the driveway lighting switched off during
daylight.
27 Forced off at opened switch The relay cannot be switched on as long as the switch is open.
