ELSNER 70681 Intra-Sewi KNX TH-L-pr- pure white RAL 9010 Built-

The Intra-Sewi KNX TH-L-pr sensor, product number 70681, is an innovative device designed for the KNX building bus system. This sensor integrates multiple functions to measure the presence of people, brightness, temperature and humidity in the environment.

Technical characteristics

The sensor is made of a plastic and glass body, available in two colors: RAL 9010 (white) and RAL 9005 (black). The dimensions of the device are 80mm in diameter and 36mm in height, with a total weight of about 50 grams.

Operating Environment

• Ambient temperature: -5°C... +45°C
• Ambient humidity (non-condensing RH): 5%... 95%
• Storage temperature: -25°C... +70°C
• Overvoltage category: III
• Pollution degree: 2
• IP protection: IP30

KNX connectivity

• Transmission medium: TP1-256
• Setup mode: S-Mode
• Maximum group addresses: 254
• Maximum allocations: 254
• Communication objects: 122
• KNX nominal voltage: 30 V DC SELV
• KNX power consumption: ≤ 10 mA
• KNX connector: insertion terminal with conductor diameter 0.6... 0.8 mm and stripping length 5 mm
• Duration after the bus voltage is restored until data is received: about 5 seconds

Integrated sensors

Presence sensor

• Detection method: passive infrared (PIR)
• Coverage angle: approximately 94° × 82°
• Range: about 5 meters

Brightness sensor

• Measurement range: 0 lux... 2000 lux
• Resolution: 1 lux at 0... 2000 lux

Temperature and Humidity Sensor

• Temperature measurement range: -5°C... +60°C
• Humidity measurement range: 0%... 100% RH
• Dew point calculation

Installation

The sensor can be installed in a false ceiling or in a standard socket (Ø 60 mm, 42 mm deep). For installation, pre-assembled supports for the false ceiling and a support ring are provided for installation in the socket.

Before installation, make sure that the device is not damaged and follow the installation instructions to avoid security risks. The initialization phase after applying the bus voltage lasts about 5 seconds, during which it is not possible to receive or send information via bus.
