High Powered Intrinsically-Safe Trunk for connecting FISCO and Entity Devices

The ROUTE-MASTER Fieldbus System uses a patented split-architecture design to deliver the highest segment current to a hazardous area of ANY intrinsically-safe FOUNDATION fieldbus™ system. ROUTE-MASTER provides two trunks (350mA each) for each segment - enough to power 16 devices (20mA each) at 500m (1,500ft)—while remaining intrinsically-safe for hydrogen-risk areas at the individual spur connection. The ROUTE-MASTER Device Couplers are available in models that handle four to 20 fieldbus devices.

ROUTE-MASTER Segment and Entity Calculator Tool Now Available

ROUTE-MASTER, the industry’s most capable Intrinsically-Safe Fieldbus Solution, now has a free and easy to use segment calculator design tool. The calculator allows you to design and document IS Fieldbus segments that include FISCO or Entity devices. Included in the tool is an intuitive Entity calculator that automatically checks your IS segments for hazardous area compliance. Go to E-HELP EXPRESS to request your FREE copy. Connect Directly to FISCO or Entity Devices The ATEX-approved version Device Couplers (RMA100C) can be installed in IIB or IIC areas connecting FISCO or Entity devices from Zone 0, 1 and 2.

Intrinsically-Safe, Isolated Power Supply

The ROUTE-MASTER's rack-mounted fieldbus power supply delivers redundant intrinsically safe segment power for up to eight fieldbus segments. The isolated segments requires no ground and have two trunks available with 350ma each. Passive conditioning and redundant DC Power ensure an exceptionally reliable fieldbus segment.

Industry-First Advantages

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.

HAZARDOUS AREA MOUNTING

ROUTE-MASTER System Design allows live working on Trunk and Field. Although ROUTE-MASTER device couplers are DIN rail mounted, they typically are supplied in Aluminium, GRP or SS Enclosures complete with glands and suitable for the area classification. The IS design of the system allows live working on the trunk and spurs for most installations. Because of the spur rating of Zone 0, Ex ia, FISCO or Entity devices can be directly connected from any zone or gas group without additional barriers.
