Reliable supplier for MTL 9108-22 Redundant FISCO power for Yokogawa CENTUM SC3000 - IIB Gas Groups.

The 9108 power supply system provides an intrinsically safe field network for Foundation™ fieldbus systems in hazardous areas.

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 9108 system builds on MTL 912x-IS range of power supplies, which have become established as the industry standard solution for FISCO networks. The 9108 system now achieves higher levels of overall system availability by providing redundancy of the power modules.

When used with intrinsically safe versions of MTL Megablock field wiring hubs, the power supply system allows complete FISCO networks to be assembled for even the most demanding process applications.
