WIRING COMPONENTS FOR ZONE 2/DIV 2 - The FCS-MBx-SG Megablocks are DIN-rail mounted passive hubs for easy connection of field devices to fieldbus networks. The established SpurGuardTM feature protects the fieldbus segment in the event of spur-short circuit faults and the spurs are certified as non-incendive allowing the connection/disconnection of field devices. MTL has a comprehensive range of enclosures that are designed to house Megablock wiring components and accessories.

FIELDBUS DEVICES (FOR ZONE 2) - Non-incendive or intrinsically safe certified fieldbus devices may be selected.

FIELDBUS BARRIERS IN ZONE 1 - The Fieldbus Barrier is a field-mounted wiring hub that creates intrinsically safe fieldbus spur connections from a non-intrinsically safe trunk. Spur short-circuit protection is provided. MTL has a comprehensive range of enclosures that are designed to house Fieldbus Barriers and accessories.

FIELDBUS DEVICES IN ZONE 0 OR 1 - FISCO or intrinsically safe entity certified fieldbus devices may be selected.

SURGE PROTECTION - The fieldbus surge protector range has been designed specifically for fieldbus installations, providing excellent protection while remaining transparent to the digital communication signals. The cost of reliable surge protection is therefore a small price to pay to safeguard the significant investment in today’s fieldbus systems.

FIELDBUS POWER SUPPLIES - These provide conditioned DC power to the field wiring and devices. MTL fieldbus power supplies cover every application, including redundant types for high-reliability applications.

HOST CONTROL SYSTEM - FOUNDATION fieldbus™ is supported by all major Control System vendors. MTL have worked closely with every supplier to develop cost effective, integrated power supply solutions.

HIGH ENERGY TRUNK - A fieldbus network interconnects transmitters and actuators to a control system over a single twisted pair cable. In this High Energy Trunk network, the trunk cannot be live-worked, but energy-limitation in the spurs allows live connection and disconnection of the fieldbus devices. The image above shows key components required to build a high energy trunk network.
