Emerson

Emerson is a global leader in process automation, measurement instrumentation, and industrial control systems including DeltaV™ distributed control systems, Ovation™ control platforms, PACSystems™ controllers, Rosemount™ measurement devices, Fisher™ control valves, and Micro Motion™ flow technologies. Emerson automation technologies are widely deployed across oil & gas, power generation, water treatment, chemical processing, life sciences, and industrial manufacturing environments requiring high-reliability process control and instrumentation. PLC Direct supplies Emerson automation hardware and measurement components supporting installed Emerson control environments. Our Emerson collection serves customers sourcing replacement DeltaV modules, Ovation control components, Rosemount transmitters, and legacy Emerson automation hardware to maintain operational continuity within existing process control systems.

Why Choose Emerson: Process Automation and Measurement Expertise

Emerson specializes in process automation architectures that integrate distributed control systems (DCS), field instrumentation, control valves, and plant-level monitoring within unified environments. Rather than focusing solely on PLC-based automation, Emerson delivers plant-wide process control solutions engineered for continuous industrial operations.

Emerson control and measurement systems are commonly deployed in:

• Oil and gas production and refining
• Power generation facilities
• Water and wastewater treatment plants
• Chemical and petrochemical processing
• Pharmaceutical and life sciences manufacturing
• Food and beverage processing
• Industrial plants requiring continuous process control and instrumentation 

This broad deployment reflects Emerson’s specialization in distributed control systems, advanced field instrumentation, and precision flow and pressure measurement technologies.

Emerson Products and Solutions

Emerson organizes its automation portfolio around distributed control systems, programmable automation controllers, measurement instrumentation, control valves, fluid automation, pneumatics, and digital plant optimization platforms. The Emerson collection at PLC Direct focuses on hardware supporting installed Emerson systems for maintenance, replacement, and lifecycle continuity.

Emerson Product Families

Emerson’s automation portfolio includes:

• DeltaV™ CHARM I/O System: Emerson DeltaV CHARM (Characterization Module) I/O delivers field-signal-level I/O within the DeltaV distributed control architecture. CHARM modules mount on VerticalPlus carrier assemblies and are independently configurable per channel for AI, AO, DI, DO, RTD, thermocouple, and HART signal types, enabling replacement of individual I/O channels without disturbing adjacent channels.
• DeltaV™ Digital Output CHARMs (KJ2101 Series): KJ2101-series modules provide digital output capability in 8-channel and 32-channel configurations, supporting 24 VDC high-side, 24 VDC low-side, 120 VAC, relay, and 230 VAC output types for field device control within DeltaV systems.
• DeltaV™ Digital Input CHARMs (KJ2201 Series): KJ2201-series modules provide digital input capability in 16-channel and 32-channel configurations, supporting 24 VDC dry contact and 230 VAC input types for discrete field signal acquisition within DeltaV systems.
• DeltaV™ Analog Output CHARMs (KJ3204 Series): KJ3204-series modules provide analog output capability in 4-channel and 8-channel isolated configurations for 4–20 mA current loop field device control within DeltaV process control loops.
• DeltaV™ Analog Input and Specialty CHARMs (KJ3102 / KJ3222 / KJ3201 Series): Analog input CHARMs cover thermocouple/mV (KJ3102), RTD 3-wire/4-wire and isolated (KJ3222), and valve position (KJ3201) signal types for precision temperature, resistance, and position measurement within DeltaV control loops.
• DeltaV™ Communication and Interface CHARMs (KJ3003 / KJ3009 Series): Communication interface modules including KJ3003 serial interface (2-port) and KJ3009 Ethernet/IP interface for integration with field devices and external systems within DeltaV architectures.
• DeltaV™ High-Speed Counter CHARM (KJ4010 Series): KJ4010-series modules provide high-speed counter and pulse measurement input capability within DeltaV systems.
• DeltaV™ Carrier and Power Hardware (KJ3001 / KJ4006 / KJ4103 / KJ4104 / KJ4105 Series): VerticalPlus carrier assemblies in 4-slot (KJ4103) and 8-slot (KJ4104) configurations, VerticalPlus Power/Controller Carriers (KJ4105), CHARM cable assemblies and terminal blocks (KJ4006), bulk 20A power supplies (KJ3001-BG1), and AC/DC 120/230VAC power supplies (KJ3001-BA1) forming the physical infrastructure of the DeltaV CHARM I/O system.
