Device Couplers

The TG200 and TG300 TRUNKGUARD™ Series Fieldbus Device Couplers have successfully completed the Foundation Device Coupler Registration Process for the Fieldbus Foundation. Five TG200 models and two TG300 models are available. The units deliver a fast and easy way to connect multiple fieldbus devices to a main fieldbus trunk in FOUNDATION fieldbus™ (H1) and PROFIBUS PA networks. The unit 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.
