Product Short Description
Product Name: Emerson CE4005S2B1 (KJ3222X1-BA1) DeltaV Series 2+ 8-Channel Isolated Analog Output Module with HART.
Product Overview: An 8-channel, optically isolated 4–20 mA analog output module for the Emerson DeltaV DCS. It drives control valves,variable frequency drives, and other HART-enabled actuators. The module integrates HART communication for device configuration and diagnostics, reducing wiring costs by 30–40% compared to separate analog and digital infrastructures.

Working Principle: The DeltaV controller sends digital output commands over the I/O bus. A 12-bit D/A converter generates the corresponding 4–20 mA current, which is optically isolated and driven through the field terminals. HART FSK signals are superimposed on the analog current for two-way digital communication with smart field devices.
Application Scenarios: Control of modulating valves, VFD speed commands, solenoid actuators, and HART-enabled smart positioners in petrochemical plants, power generation, water treatment, and pharmaceutical manufacturing.
Installation & Usage Notes:
- Insert into any slot of a DeltaV 8-wide I/O carrier; the system auto-detects the module
- Use A4-keyed KJ4001X1-CA1 termination block for proper mating
- Respect the 300 mA maximum field circuit power budget per card
- For hazardous area (ATEX Zone 2) installations, follow Emerson’s prescribed wiring and grounding practices
- Hot-swap only in non-hazardous areas during planned maintenance windows
- Connect shield of field cables to earth ground at one end only to prevent ground loops
