PRODUCT DESCRIPTION
ALF111-S00 S1 FOUNDATION Fieldbus Communication Module
Yokogawa ALF111-S00 S1 is the ALF111 FOUNDATION Fieldbus communication module for compatible CENTUM field control stations. It connects configured H1 fieldbus segments to the station process-control project.
The module provides four H1 ports at 31.25 kbit/s, with pressure-clamp connections and selectable built-in terminators. Two adjacent modules can form the documented redundant arrangement. Segment loading, device capacity and function-block allocation must follow the applicable station and fieldbus design.
