Water network efficiency AquaLink technical specification Models AQ3 loT Data Logger GSM 2G/3G/4G 2,4,5,+ Relay The AquaLink Data Logger with GSM communication offers advanced functionality for monitoring water distribution systems. It features muLtipLe input ports (cabLes) that aLLow connection to 4D/5A inputs, providing versatility for various measurement needs. Additionally, it can be optionally equipped with 2 reLay outputs, which can controL vaLves, pumps, and other devices. With its IP68 waterproof rating, the Logger is resistant to water ingress, ensuring reliable operation even in chaLLenging environments. The externaL SMA connector enabLes easy antenna replacement, whiLe the option to repLace batteries ensures extended device Lifespan. Moreover, the built-in humidity and temperature sensor continuously monitors environmental conditions to controL moisture ingress into the device. Designed for ease of maintenance, the device's moduLar design aLLows for the replacement of onLy the upper part of the Logger in case of electronic faiLure, whiLe aLL cabLe connections remain intact in the shaft. • 5x programmable inputs (4x Digital/Analog/4-20mA + 1x Analog/4-20mA) with programmable power output for each input • Dedicated AQPressure input • Switch alarm input • Internal humidity and temperature sensor for detection of water intrusion inside housing Outputs: Optional • 2x solenoid/relay pulse output with programmable voltage output 3,3V-20V, reverse polarity support and up to 20W pulse • Built- in optional GSM modem (GSM/GPRS/EDGE/UMTS/HSDPA/HSPA+/LTE-TDD/LTE-FDD) • Digital (measures pulses from HRI, REED, Cyble, short circuit...) - counter mode • Analog (measures voltage 0-3V) • 0/4-20mA current loop (2,3 and 4 wire type support) Each input can generate a separate power output on a dedicated pin to power the connected sensor using internal batteries every time a measurement is taken. The voltage generated for each input and the duration of power is configurable for each input, with selectable voltages from 3,3V to 20V and configurable current limits up to 4A in 50mA steps. • Built- in optional GSM modem (GSM/GPRS/EDGE/UMTS/HSDPA/HSPA+/LTE-TDD/LTE-FDD) • GPRS and SMS communication (configurable) to a AquaWeb server • Accepts normal size SIM cards • Integrated Bluetooth for on site programming (v4.2BR/EDR) • Local connection trough USB cable (for initial configuration and troubleshooting) Mechanical: Housing: IP68, DIN rail option 160 x 80 mm 700g (without cables) ip ties or wall mounts Operating environment: Temperature range: Reduced battery life outside -20°C and +65°C Power supply: • Up to 3x 3,6V Li-SOCI2 internal batteries • External power supply range from 3,6V to 15V, with auto fail-over to internal backup battery • Standard battery life up to 6 years (depending on configuration) • Batteries easily replaceable • Optional mains / solar power supply / rechargable batteries EN AQIII 2 AQ Link GmbH reserves all the rights to changes product specifications at any time without notice.
