TS Series TRUNKSAFE® Fault-Tolerant Fieldbus System Get Data Sheet TRUNKSAFE.pdf (1.3M ) TRUNKSAFE in an Eggshell (590K ) * Patents Pending	TRUNKSAFE TS Series Fault-Tolerant Fieldbus System The TRUNKSAFE Fault-Tolerant Fieldbus System provides a cost-effective, yet highly reliable, strategy to maintain continuous communications between field devices and a Distributed Control System in the event of any single point failure (such as an open- or short-circuit) on a FOUNDATION fieldbus™ H1 or PROFIBUS PA segment. The First Redundant Fieldbus Physical Layer TRUNKSAFE is comprised of two redundant fieldbus DC power conditioners and specially-engineered device coupler (6- and 12-spur models) that, in combination, provide a secure, and redundant, fieldbus physical layer. Implement a redundant, yet cost-effective, fieldbus physical layer for important and plant-critical segments. Maintain all process and diagnostic communications without interruption, even if the network cable is broken or shorted. Compatible with FOUNDATION fieldbus H1 and PROFIBUS PA networks and devices without hardware or software changes. Advanced physical layer diagnostics monitor and report open- and short-circuits, DC power status and segment noise. Electronic and fully auto-resetting spur short-circuit protection that prevents segment failure caused by single device faults. DIN-Rail and Complete Field-Mount Packages TRUNKSAFE Device Couplers and Power Conditioners snap onto standard DIN-rail. To reduce specification and installation time, device couplers can also be ordered in a variety of our ready-to-install field-mount, weather-proof enclosures complete with cable glands.
TG200 TRUNKGUARD® Series 200 FOUNDATION Fieldbus™/PROFIBUS PA Device Coupler (For General Purpose and Non-Incendive Installations) Get Data Sheet tg200.pdf (494K )	TRUNKGUARD Series 200 Fieldbus Device Couplers (TG200) deliver a fast and easy way to connect multiple fieldbus devices to a main fieldbus trunk in FOUNDATION fieldbus™ (H1) and PROFIBUS PA networks. General Purpose and Hazardous Area Installations For installation in General Purpose and Non-Incendive (Class 1, Division 2) areas, TRUNKGUARD Fieldbus Device Couplers can be matched with our FPS200 Fieldbus Power Supplies. For intrinsically-safe applications, see the RM100 Intrinsically-Safe Fieldbus System. For installation in Zone 1 areas, see the TG300 Series Fieldbus Device Coupler. Industry-First Advantages Available in 4-, 8-, 10-, 12- and 20-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 auto-termination feature 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 TG200 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. 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 GRP (Glass Reinforced Polyester) and stainless steel enclosures with glands for armored or unarmored cable.

Designed for Zone 1 Areas The TRUNKGUARD 300 Series Fieldbus Device Coupler is designed and approved for use in Zone 1 and Zone 2 with flameproof Exd devices. Each device coupler channel can be manually de-energized using a key-operated magnetic interlock. This allows individual fieldbus devices to be disconnected from the fieldbus segment without de-powering the entire segment, even in Zone 1 areas. The fieldbus device coupler's LED indicators show the current state of each channel (NORMAL, FAULT or DE-ENERGIZED). Industry-First Advantages Available in a 4- or 8-spur configuration, the TRUNKGUARD 300 Series is the first to provide fully automatic segment termination. The patented technology prevents fieldbus segment failure from under- or over-termination, a major problem in fieldbus startups.
