Simplifies Networking

The TROLL^® Net Hub is a low-power, networking device capable of connecting either four or eight instruments. Use the hub to network up to 16 devices (connected by up to five TROLL Net Hubs).

You can customize a system for your application by attaching a variety of In-Situ^® instruments to the hub, including RDO^® PRO Probe; Aqua TROLL^®; Level TROLL^® 300, 500, and 700; and BaroTROLL^® Instruments.

• Networks to telemetry or SCADA/PLC system
• Uses 9-36 VDC power source
• Uses solar power in conjunction with TROLL^® Link Telemetry System
• Each cable within the network has a maximum length of 1219 m (4000 ft) per RS485 protocol (does not support SDI-12 or 4-20 mA).

Saves Time & Money

• Connects up to 16 instruments into one telemetry system
• When using a TROLL Link Telemetry System, allows the user to access data via Win-Situ^® 5 Plus Software or the web-based In-Situ^® Data Center.
• Extends instrument battery life — The hub passes power to attached instruments when connected to external power.
