•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
•multiple control functions

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.
