Features of TG200 Fieldbus Device Couplers:

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.
Short Circuit Protection
- On detection of excess current on a fieldbus spur, the TG200 reacts immediately (20 microseconds) 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.
