MooreHawke's TRUNKGUARD Series 200 Fieldbus Device Couplers (TG200) are a fast and easy way to connect multiple fieldbus devices to a main fieldbus trunk in FOUNDATION Fieldbus H1 and PROFIBUS PA networks. They are designed for installation in General Purpose, Non-Incendive and Zone 2 applications and are available in ready-to-install, field mount enclosures.

Protect Spurs from Segment Faults: On detection of excess current on a fieldbus spur, the TG200 reacts immediately (20 microseconds) to switch spur current to a nominal trickle-level. With removal of the short, the spur is automatically reconnected to the fieldbus segment. This is a significant advantage to "current-limiting" designs on other device couplers, which hold a fault permanently on the segment at a higher than normal current level. This often results in segment failure by overloading the segment power supply.

Automatic Segment Termination: Patented Automatic Segment Termination eliminates the most common installation error: segment failure from under or over termination. Its auto-termination feature assures that local parts of a fieldbus segment will continue with proper termination even if remote parts of that segment are accidentally disconnected. This prevents costly downtime and hazardous situations.
