C-BUS TRAINING MANUAL - VOL 1

3.1 Voltage Free Relay

The C-Bus 55xRVF Series Voltage Free Relays are relay-switching devices designed to be mounted in

electrical switchboards or similar enclosures (an example is shown in Figure 4). For ease of installation,

they are DIN rail mounted, measuring 12 DIN modules wide.

Several independent voltage free relay contacts are provided for general switching applications. The

series includes units with 10A rated relays for resistive, inductive (lighting loads) or ﬂ uorescent loads.

There is also a 20A version.

Units are available with or without a 200mA C-Bus power supply, for powering other C-Bus units

connected to the network.

3.2 Voltage Free Changeover Relay

A C-Bus L5504RVFC Series Voltage Free Changeover Relay is used in an application where

changeover contacts are required. These units are typically used to operate three-speed motors and

two-way motor control devices, such as motorised blinds, shutters, curtains and skylights.

Four independent voltage free, changeover relay contacts are provided, each with normally open,

normally closed and common terminals. They are available with or without an internalC-Bus power

supply. Units with a power supply are capable of supporting other C-Bus units (200 mA capacity).

Voltage free changeover relays are suitable for use with resistive, inductive, ﬂ uorescent and

incandescent loads.
