Moore TG200 TRUNKGUARD Device Couplers provide electronic and fully auto-resetting spur short-circuit protection. This prevents segment failure caused by single device faults. Utilising a “FoldBack” technique, any spur that attempts to draw more than 48mA is automatically switched off and not permitted any current flow until the fault is removed. A trickle current is used to
determine when the short has been removed. During a short, only 4-5mA is used. This is a significant advantage to “current-limiting” designs on competing units 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. With removal of the short, TRUNKGUARD automatically reconnects the spur to the fieldbus segment.
