Fieldbus Expanders

All Relcom Legacy Fieldbus segment wiring blocks can be expanded for additional wire pair connections by using the Expander Block, FCS-E. Each Expansion Block provides four more cable connection points. The Expansion Blocks plug into a Terminator, Spur Block, Balanced Power Conditioner, Power Hub, or into each other so that wiring between blocks is eliminated. As many Expansion Blocks as needed can be used on a Fieldbus segment. The Expansion Block has an LED which illuminates to indicate bus power is present.

The Expanders are part of our Legacy Fieldbus interconnection blocks. For new designs, we recommend our Megablock Series.
