RXC40.1

RXC40.5

Extension to the RXC30

/ RXC31 / RXC38 room controller

The RXC40 extension module is used in conjunction with an RXC30, RXC31 or

RXC38 room controller for the control of lighting in individual rooms.

• Switching and dimming control of two lighting zones

• Application software downloadable into RXC30 / RXC31 / RXC38 basic module

• Plug-in connection to RXC30 / RXC31 / RXC38 basic module

for power supply and data

• Volt-free relay contacts for lighting control (12 A)

• Control outputs for dimming control of lights (DC 1...10 V external)

Application

The RXC40 module acts as an I/O extension to the basic RXC30 or RXC31 / RXC38

room controller. The input/output configuration is optimized for the control of two zones

of dimmable lights.

The RXC30 / RXC31 / RXC38 basic controllers and the RXC40 extension module are

connected electrically and (when the terminal covers are fitted) mechanically to form a

single unit. If required, this can be supplemented with an RXC41 extension module for

the control of blinds.

For operation, either conventional momentary-contact switches, or integrated operating

units with a bus connection, may be used.

The application software for the complete unit, comprising the basic module and the extension module(s) is downloaded into the basic module, the RXC30 or RXC31 room controller. If the RXC30 / RXC31 / RXC38 controller is downloaded with basic application 00030 / 00031, test functions for the RXC40 extension module are also available. Functions The functioning of the RXC40 extension module is defined by the application software downloaded into the RXC30 or RXC31 / RXC38 room controller.
PAGE 3
Mechanical design The RXC40 extension module consists of a housing base, a housing cover and the printed circuit board with connection terminals. The module also has a ribbon cable and connector for connection to the RXC30 / RXC31 / RXC38 basic controller, and a connector base into which a further extension module may be plugged.

3834J01 STOP Note! Cable restraints on the housing base must be used for the wires to terminals 7 … 12 and 15 … 17 (AC 230 V). The conductors must be secured with cable ties (see diagram). Warning! Ensure that the power is off before inserting or removing plug-in terminals connected to a mains voltage. Communication The RXC40 extension module communicates via a serial bus connection (the PE bus) with the basic controller RXC30 / RXC31 / RXC38.

DC 1...10 V control outputs The control outputs are designed for control of dimmable electronic ballast units or dimmable transformers. The current is supplied by the ballast unit or transformer. The outputs are not suitable for controlled devices such as valve actuators with a DC 0 … 10 V input. The analogue output circuits are electrically isolated with 4 kV from the other module electronics.
