F100 TERMINATORS

The F100 Terminator is a DIN rail mounted Terminator for Foundation Fieldbus and Profibus PA networks that also include some surge protection*. These Terminators provide the second Terminator for the network which is located in the field near a Legacy Megablock. The F100 is certified for Div 2/Zone 2 Hazardous Locations.
The Terminator is easily wired to any Megablock to provide one of the two Terminators required on the segment. The Terminator is clearly marked with a large "T" for easy identification by field personnel.
* Although the Relcom Terminators have some surge protection built in, it is not considered comprehensive for a distributed architecture such as that used with Fieldbus. For comprehensive surge protection, please see MTL’s FS32, FP32, and TP32 products on their website (MTL Fieldbus Surge Protection).
