Good quality MTL 910x-22 4-segment, redundant FISCO power systems for IIB Gas Groups products for your reference.
The 910x 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 energised 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.
