A robust family of smart data loggers capturing measurements from diverse sensors via analog and digital interfaces. Powered by a 32-bit 900 MHz processor and 24-bit ADC with edge computing for AI-based IIoT applications.
Features
Every capability purpose-built to deliver reliable, accurate data acquisition in the harshest field conditions.
24-Bit ADC Resolution
Industry-leading 24-bit ADC with over 20 ENOB ensures high-fidelity conversion across all analog inputs — essential for bankable IEC-compliant datasets.
Multiple Input Channels
4 differential or 8 single-ended inputs on XG920, 8 differential or 16 single-ended on XG930 — scale sensor count without adding hardware.
IEC Class A Compliance
Compliant with IEC 61724-1:2021 and IEC 61400-12-1:2022 — delivering auditor-ready datasets for solar WMS and wind metmast applications.
Multiple Serial Interfaces
RS232 (×2), RS485 (×2), and SDI12 provide simultaneous Modbus master/slave, NMEA output, and sensor bus — all from one device.
Multi-Protocol Communication
Ethernet, Wi-Fi, Bluetooth, and 4G LTE with Modbus TCP, IEC 60870-5-101/104, SFTP, HTTP, and HTTPS — connects to any network architecture.
Precision Time Synchronisation
GPS, cellular NTP, and onboard RTC with battery backup ensure timestamps are aligned across all logged parameters.
Robust Data Storage
8 GB internal + 32 GB SD card expandable, CSV format, USB pen drive retrieval, and web download — over 5 years of data with zero gap.
IP65 Environmental Protection
PC UV-protected housing rated IP65 for −40°C to +70°C operation — engineered for long-term outdoor deployment without compromise.
Energy-Efficient Operation
Under 10 W total consumption on 9–28 V DC input with surge protection — runs continuously on a 20 W solar panel in off-grid sites.
