ROUTE-MASTER Series 100 Fieldbus System delivers isolated and redundant intrinsically-safe segment power and device connectivity for FOUNDATION fieldbus?(H1) and PROFIBUS PA networks. Using a patented split-architecture design, the system delivers the highest segment current of ANY intrinsically-safe fieldbus system for the largest number of devices and/or the longest segment cable, with cable lengths of up to 1900m trunk and 120m spurs. ROUTE-MASTER enables 350mA power per fieldbus segment in intrinsically-safe applications, which permits up to 16 fieldbus devices at 500 meters (1500 feet), even in hydrogen-risk areas.
Intrinsically-Safe, Isolated Power Supply
The ROUTE-MASTER's rack-mount fieldbus power supply delivers intrinsically-safe segment power and communications to up to eight fieldbus segments to fieldbus devices mounted in a hazardous area. It provides a fully-isolated, redundantly-powered, passively-conditioned and intrinsically-safe trunk for connection into a hazardous area. No I.S. ground is required. The 350mA fieldbus segment capacity is the greatest available for any I.S. configuration, and allows normal segment design rules without undue restriction. To minimize segment voltage drop, and maximize the power available in the field, the ROUTE-MASTER can be wired to provide dual outputs from the same fieldbus segment input.
Industry-First Advantages
Available in 4-, 8-, 10- and 20-spur models, ROUTE-MASTER Fieldbus Device Couplers use the same technology as our industry-first TRUNKGUARD Fieldbus Device Couplers to provide fully automatic segment termination. The patented technology prevents fieldbus segment failure from under- or over-termination, a major problem in fieldbus startups. The ROUTE-MASTER's auto-termination feature assures that local parts of a fieldbus segment will continue to function if remote parts of that segment are accidentally disconnected. This prevents costly downtime and hazardous situations. Other unique features include diagnostic LEDs that positively indicate power status on each spur, spur short circuits, status of auto-termination, as well as convenient connections for a fieldbus hand-held configurator.
Short Circuit Protection
On detection of excess current on a spur, the ROUTE-MASTER reacts immediately 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 segment.
DIN-Rail and Complete Field-Mount Packages
ROUTE-MASTER 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.
