LDRBUS

BUSing® light level detector

Controls the installation according to the level of light measured.

•	BUSing® light detector.
•	Discreet digital PI regulator incorporated.
•	Consumes 40mA. Supply via BUS.
•	2 operational modes: linear mode and threshold mode.
•	Admits Lineal, All or Nothing, or Sectorial controls.
•	Embedded in wall or ceiling.
•	Size: Ø Embedded 25mm - Ø Seen 36mm - Length 50mm

Description

Light level detector with regulator incorporated that controls lighting loads according to the level of light available.

It can be used to maintain an even level of light in rooms, using regulated lighting that is controlled by BUSing®.

With the regulator parameters correctly adjusted, light levels in rooms can be maintained regardless of natural light available.

Technical Characteristics

Inputs

Configuration using the Development System

•	Off Mode: The device does not execute any action but it continues measuring light level.
•	Linear Mode: The device maintains, automatically, the level of light indicated at the input, acting on the devices it controls (according to the fixed regulation law in the fixed parameters of the PI). This device can control on/off points, operating as a threshold switch. The devices that it controls are programmed as a list of elements using the Development System (SIDE)
•	Threshold Mode: Admits 4 scenes to be programmed, when the lighting is between configurable values.

Practical case

Combining it with a presence detector (SRBUS, SifBUS type) you can control lighting according to the presence and available lighting at the same time.
