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^® sensors to the hub — RDO^® PRO; Aqua TROLL^® 100 and 200; Level TROLL^® 300, 500, and 700; and BaroTROLL^® instruments.

• Networks to telemetry or 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.
