More Information:   TG300 TRUNKGUARD Series Fieldbus Device Couplers deliver a fast and easy way to connect multiple fieldbus devices to a main fieldbus trunk in a FOUNDATION fieldbusTM (H1) network. General Purpose and Hazardous Area Installations TRUNKGUARD Series 300 Device Couplers simplify the use of high power or Exd fieldbus devices in Zone 2 and Zone 1 by allowing "live" access for maintenance and eliminating the need for expensive Exd/Flameproof junction boxes. The TG300 can be matched with our TPS400 Fieldbus Power Supplies. Industry-First Advantages Available in 4-, and 8-spur models, TRUNKGUARD is the first fieldbus Device Coupler to provide fully automatic segment termination. The patented technology prevents fieldbus segment failure from under- or over-termination, a major problem in fieldbus startups. The TRUNKGUARD's patented "Automatic Segment Termination" assures that local parts of a fieldbus segment will continue to function if remote parts of that segment are accidentally disconnected. This prevents costly downtime and hazardous situations. Other unique features include diagnostic LEDs that positively indicate power status on each fieldbus spur, spur short circuits, status of auto-termination, as well as convenient connections for a fieldbus hand-held configurator. Short Circuit Protection On detection of excess current on a fieldbus spur, the TG300 reacts immediately to switch spur current to a nominal trickle-level, rather than limiting the fault current to a fixed (and always higher) level as is typically done by competing units. With removal of the short, the spur is automatically reconnected to the fieldbus segment. Easy Hazardous Area Installation ATEX approvals allow installation in Zone 1 and Zone 2 areas. DIN-Rail and Complete Field-Mount Packages TRUNKGUARD Fieldbus Device Couplers snap onto standard DIN-rail. To reduce specification and installation time, they can also be ordered in a variety of our ready-to-install field-mount, weather-proof enclosures complete with cable glands. Options include aluminum, GRP (Glass Reinforced Polyester) and stainless steel enclosures with glands for armored and unarmored cable.
