Emerson

Emerson automation hardware includes distributed control, I/O, controller, communication, power and interface modules used in process-control systems such as DeltaV and related platforms. The architecture commonly separates controller processing from field I/O, using modular carriers, terminal blocks, network interfaces and power components to connect plant signals with the control network. Modules can support analog and discrete signals, fieldbus communication, controller redundancy, diagnostics and system-level data exchange. This collection brings together Emerson components used for process measurement, regulatory control, sequencing, field-device integration and control-system expansion. It covers multiple hardware generations encountered in operating plants, allowing engineers to identify replacement parts by model, module type and system role when maintaining installed DCS and automation equipment.
