VMB4RYNO 4-channel relay module user manual - version 1 9
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 (0.5mm
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).

A single-pole load (e.g. lighting) can be connected directly to the output.
