Fisco in fieldbus
Webthat repeat the fieldbus signal from the field to the host and power both the fieldbus segment and the host. This chapter addresses FISCO IS applications with devices in Class I Division 1 or Zone 1 EExib locations. If a field device in your application is not certified for FISCO IS, an MTL Fieldbus Entity Spur Adapter can be used. Webdevices, Fieldbus users reduce the amount of I/O and control equipment required. A Fieldbus-compliant twisted-pair of wires carries signals between the field devices and the networks. Fieldbus also reduces the number of Intrinsically Safe (IS) barriers, cabinets, cables and connectors required. Since the wire pair can support

WebFieldbus requires proper termination. The bus terminators create the load that translates the fieldbus signal transmitted as a current change into a detected voltage on the cable. This accentuates the importance of proper and reliable bus termination, which plays an important role in system availability. WebFISCO As fieldbus became more popular in process applications in the 1990s, the Fieldbus Intrinsically Safe Concept (FISCO) and the related FNICO1 sought to enhance the Entity concept by simplifying system calculations and allowing more power, and therefore more devices, on the wire. With FISCO, only one power supply is permit-

For example for a segment with 16 x 15mA devices powered by a 9122-IS IIB FISCO power supply, the segment will normally require 240mA which is less than 265mA 9122-IS design current.
