The ABB i-bus Light Controllers, LR/S x.16.1 (x = 2 or 4) are KNX modular
installation devices (MDRC) in ProM Design for installation in the distribution
board on 35 mm mounting rails. The connection to the ABB i-bus
implemented via a bus connection terminal on the device shoulders.
The LR/S can control dimmable electronic ballasts or transformers with
a 1-10 V interface via two or four outputs – depending on the device
concerned.
For every output a floating switching contact (16 A) for direct switch on and
off of the ballasts are available. The switching relays are particularly suitable
for switching fluorescent lamp loads (AX) to DIN EN 60 669.
Manual switch ON and OFF of the individual outputs is possible in manual
control independently of the bus or auxiliary voltages. The operating element
on the switching relay directly indicates the switch status.
A separate Light Sensor LF/U 2.1 can be separately connected on the Light
Controller for each output. The light sensor measures brightness in closed
rooms. The Light Controller undertakes constant light control for each output
(control circuit) with this brightness value. It is possible to use several Light
Sensors for a single output.
The Light Controller and the connected Light Sensor are supplied with power
via the KNX and do not require any additional power supply.
