Fisco in fieldbus
WebNov 22, 2005 · Fieldbus segments with only 4 devices somewhat defeated the point of early fieldbus justifications; plants still had lots of cable, and hardware costs went up. Technology stepped up to the challenge in the form of FISCO (Fieldbus Intrinsically Safe Concept) which was developed in the late 1990s. WebThe MTL 9122-IS is a fieldbus repeater isolator which repeats the fieldbus signal from a safe area, Zone 2 fieldbus to an intrinsically safe fieldbus for connection to devices in Zone 1. The 9122-IS provides up to 265mA, typically powering up to 16 x 20mA field devices in Gas Group IIB. The 9122-IS is certified to FISCO (Fieldbus Intrinsically Safe

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- WebThe high-power trunk concept with Entity or FISCO devices: Connect the maximum number of devices to the same fieldbus trunk; and at the same time makeuse of maximum cable lengths. This concept utilizes standard power supplies such as the easy-to-install and configuration-free power hub.
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.
