The LPR 8 Series (Low Power Radio 868MHz) represents a real innovation and a major advance in radio data transmission technology!
Usual applications: Building automation, well access control, etc.
The LPR8 module is a radio transmitter-receiver using the license-free 868 MHz frequency band. The radio transmission is the ideal solution face to cabling stress (physical, civil engineering, cost, etc.). Its single block and waterproof design with its integrated antenna, makes it perfect for applications such as data acquisition or remote reading on not very accessible outdoor sites or on long distances. Its very low power consumption confers it a very large lifetime: 10 years for 2 transmissions daily, thanks to the use of Lithium battery. The LPR8 module is available in different versions depending on the used interface.
Regarding the interface used, LPR8 module has following different versions:
LPR8-FL 1 or 2 points survelliance / Digital input signal (reed & NPN) / Max.
survelliance frequency = 2 Hz.
LPR8-TH Digital termistor heat measurement / range (-55) - +125°C, accuracy 0.5°C,
LPR8-PT Pt100 heat measurement / 1 channel
LPR8-AI Analogue input with 0-5V or 4-20 mA external power supply / 1 channel
LPR8-DO 9-relay consantrator module (with max. 3 LPR8-DI module repeater) / IP50
metal case for DIN rail / 10-30Vdc external power supply
LPR8-RP Repeater for very long range / 25mW - 500mW
