MooreHawke TG200 TrunkGuard Series fieldbus device couplers use a fold-back technique that detects a short in an instrument, disconnects that spur from the segment and illuminates an LED. TG200 device couplers are available with four, eight or 10 fieldbus spurs and work with Foundation fieldbus H1 and Profibus-PA interfaces. Couplers can be DIN-rail mounted or enclosed in IP66-rated glass-reinforced polyester (GRP) or stainless steel enclosures. Up to 32 fieldbus devices can be accommodated in a single segment.
