4System overview
The EasyBus3® system is designed to remotely control slave devices over a proprietary power line
communication (PLC). The slave devices are specifically designed to match building automation
ventilation system needs such as fire dampers, variable valves, general purpose inputs and outputs,
and more…
The system is composed of three types of devices which are described here below.
Easy3-H
The Easy3-H device is the main controller of the system. It is the communication gateway between the
building automation control system and the Easybus3® network. It is capable to manage up to three
Easy3-M devices.
Easy3-M
The role of the Easy3-M device is to communicate with the remote slave devices using powerline
communication over the mains network (230 VAC). One Easy3-M is able to control up to 128 slave
devices. The Easy3-M device must be connected to an Easy3-H using a dedicated cable.
Slave devices
Different types of slave devices are available. Each type is designed for a specific function such as fire
damper motor control, variable valve control, general purpose inputs and outputs, and more… They are
connected to the mains network and communicate with the Master using powerline communication over
the mains network.
Please refer to specific EasyBus3® slave devices product specification for complete
description.

Remote Easy3-M devices
In the main topology, the Easy3-M devices are intended to be placed together with the Easy3-H module
in the building electrical panel.
But it is also possible to relocate the Easy3-M modules next to the ventilation systems while
respecting a maximum and total distance of 100 meters between the Easy3-H and the far-most
Easy3-M(s).
In this configuration Easy3-M(s) must be located in a dedicated electrical cabinet.
