Crouse-Hinds series MTL 910x FISCO power supply systems provide an

intrinsically safe field network for Foundation™ fieldbus systems in

hazardous areas. Variants are available for integration into proprietary

fieldbus control systems. The output of the power supply modules

complies with the Fieldbus Intrinsically Safe Concept (FISCO) model,

in accordance with IEC standard 60079-27. 

The key advantages of FISCO over earlier ‘Entity’ model installations

to FF-816 are higher available field current and reduced safety

documentation, while retaining the ability to conduct maintenance

while energized and without “gas clearance”.

The 910x systems build on MTL 912x-IS range of power supplies,

which have become established as the industry standard solution for

FISCO networks. The 910x systems now achieve higher levels of overall

system availability by providing redundancy of the power modules.
