Onset HOBO U30-NRC-VIA-05-S100-000 Weatherproof Data Logger with 5 Smart Sensor Inputs

Onset HOBO U30-NRC-VIA-05-S100-000 Data Logger

The Onset HOBO U30-NRC-VIA-05-S100-000 is a multifunction data logger designed for reliable, long-term environmental monitoring in demanding conditions. With its rugged, weatherproof enclosure (tested to NEMA 6) and support for up to 5 smart sensors (expandable to 10), this logger is ideal for applications such as agriculture, meteorology, hydrology, and industrial process monitoring. The U30-NRC-VIA-05-S100-000 also includes 2 analog input channels with sensor excitation, allowing connection to a wide range of third-party sensors. Its fast USB offload and optional solar power capability make it a flexible and dependable choice for remote and unattended deployments.

Key Features & Highlights

• 5 Smart Sensor Inputs: Compatible with most Onset smart sensors (excluding S-BPA, S-TMA, S-THA), with option to expand to 10 inputs.
• 2 Analog Sensor Ports: User-configurable for 0–20 mA, 0–2.5 V, 0–5 V, 0–10 V, or 0–20 V inputs with 12-bit resolution and switched 12 VDC excitation.
• Rugged Weatherproof Enclosure: Double-enclosure design with ABS blend outer shell and polycarbonate inner shell, tested to NEMA 6 for water and dust ingress protection.
• Fast Data Offload: Full-speed USB via mini-B connector for quick data retrieval.
• Alarm Output Relay: User-configurable relay (normally open or closed) rated for 30 V, 1 A max, can be activated, deactivated, or pulsed on alarm conditions.
• Flexible Power Options: Rechargeable sealed lead-acid battery (4 V, 4.5 or 10 Ah) with optional solar panels (SOLAR-1.2W, SOLAR-3W, SOLAR-6W) or AC adapter (AC-U30).
• Large Data Storage: 512K bytes nonvolatile flash memory with stop or wrap-around modes.
• Wide Operating Range: Normal range -20°C to 40°C; extended range -40°C to 60°C (battery life reduced).
• Easy Mounting: Can be mounted on a 1.5-inch mast or wall, with hinged door secured by latches and padlock eyelets.

Applications

This data logger is well-suited for environmental monitoring in agriculture (soil moisture, weather stations), hydrology (water level, water quality), and industrial settings (process monitoring, equipment performance). Its robust construction and flexible sensor compatibility make it a trusted tool for researchers, engineers, and facility managers who require accurate, long-term data collection in harsh environments.
