FOXBORO FDC280 RH101FQ Field Device Controller

FOXBORO FDC280 RH101FQ is a field device controller for EcoStruxure Foxboro I/A Series & Foxboro Evo DCS platform. It supports direct connection to serial and Ethernet field instruments, acting as a distributed intelligent controller to realize field data collection and independent process control without extra FBM fieldbus modules.

This unit adopts dual-core processor architecture and supports simplex or redundant fault-tolerant configuration. It supports multiple mainstream communication protocols and built-in comprehensive hardware self-diagnosis. It is widely supplied as replacement spare parts for petrochemical, power and oil & gas process automation systems.
