RUGGEDIZED, LOW POWER, RADIO NODES

Available today as pulse counting, light pulse counting, temperature or temperature and relative humidity nodes, S40 Series covers most of the needs for metering or environmental monitoring applications

Available today in Wireless M-Bus or LoRaWAN, S40 Series is available with internal or external antennas

Key features of maestro S40 series

  • IP68-rated, tiny, automotive-grade, non-flammable (UL 94’s V-0), UV-resistant, 30% fibreglass-reinforced polyamide, casing

  • Single C battery-operated for longer life than mostly AA battery-operated competitors

  • One- or two-metre-long 3 wire harness with tampering detection

  • SMA antenna connector for antenna remoteness and / or use in better-penetration VHF spectrum

  • ‘Tropicalised,’ non-potted, design for proper disposal and, if need be, replacement of the battery / repair

  • Optional DIN Rail clip / mounting bracket

WIRELESS TECHNOLOGIES

WIRELESS M-BUS

  • Full compliance with Open Metering System (“OMS”) specification

  • Bubble-Up® operation with Listen Before Talk (“LBT”) for approx. ten-year lifespan while performing twelve hourly readings in the UHF spectrum

  • Very fine granularity, perfectly suited to Energy optimisation markets

  • Remote node reconfiguration

  • Easy, LED-assisted, initial configuration via magnetic keys

LoRaWAN™

The LoRaWAN™ specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.
