SpurGuard™ is a device-port, short circuit protection technique

that minimizes susceptibility to single points of failure. The F300

Megablock has built-in SpurGuard™ protectors that prevent a short

circuit in any of the individual field devices or spur cable runs, from

bringing down the entire fieldbus segment. A red LED near each

spur connection indicates when a spur is shorted and hence in “over

current” mode.

The optional FS32 modules can provide surge protection for the

F300 products on both the trunk and spur terminals. These pluggable

modules are simple to fit in a new installation, or as a retrofit option.

A range of MTL Process Junction Boxes in stainless steel and carbon

loaded, glass-reinforced polyester are available for mounting Megablock

wiring components. They offer plenty of space for termination and

wiring, making it easy to install and maintain the fieldbus system.
