EMERSON DeltaV KJ3221X1-BA2 8-Channel 4-20mA HART Series 2 AO

EMERSON DeltaV KJ3221X1-BA2 8-Channel 4-20mA HART Series 2 AO

This 8-channel analog output (AO) module is part of the Series 2 I/O card family for the Emerson DeltaV distributed control system (DCS). It is specifically designed to provide controlled 4-20mA DC current signals with HART digital communication signals to field actuators.

Key Features & Detailed Description

Core Functions Explained

1. High-Precision Analog Output

   • The module generates highly accurate and stable 4-20mA current signals for the continuous control of field devices. For example, it can precisely control valve opening (0%-100%), variable frequency drive speed, etc.

2. Integrated HART Communication

   • HART (Highway Addressable Remote Transducer) is a digital communication protocol that superimposes a low-frequency digital signal on the standard 4-20mA analog signal.

   • This module integrates a HART modem, allowing the DeltaV system to:

     • Device Configuration: Remotely configure and parameterize HART-enabled field devices (e.g., smart valve positioners).

     • Diagnostics & Monitoring: Read diagnostic information and secondary variables from field devices (e.g., actual valve feedback position, alarm messages).

     • Calibration: Support remote calibration commands.

3. Channel-to-Channel Isolation

   • All 8 channels are individually isolated. This means a problem on one channel (e.g., a short circuit or failure) will not affect the others, significantly enhancing system reliability and availability.

4. Series 2 I/O Advantages

   • High Density: Provides 8 channels in a single card, saving cabinet space.

   • Hot Swappable: Supports online installation or removal without powering down the system, facilitating maintenance without interrupting the process.

   • Auto-Identification: The DeltaV system automatically recognizes the inserted card type, simplifying configuration and maintenance.

   • Reliability: Utilizes more advanced electronic components and design for a higher Mean Time Between Failures (MTBF).

5. Safety and Diagnostics

   • The module features comprehensive internal diagnostics capable of detecting faults such as open circuits, short circuits, and out-of-range conditions, reporting them promptly to the DeltaV controller to ensure system safety.

Role in the DeltaV System Architecture

1. The Controller executes control logic and calculates the required output value.

2. The KJ3221X1-BA2 AO Module receives the output command in digital form from the controller via the backplane bus.

3. The module converts the digital command into a precise 4-20mA analog signal.

4. The signal is routed to the field device via an I/O termination assembly (CHARM or conventional).

5. The Field Actuation Device (e.g., control valve, electric actuator, variable frequency drive, I/P converter) receives the 4-20mA signal and acts accordingly.

6. Simultaneously, the module engages in bidirectional digital communication with smart field devices via the HART protocol for monitoring and device management.

Typical Applications

This module is widely used in industrial automation fields requiring precise continuous control, especially in plants that use or plan to use HART smart devices.

• Position control for Control Valves / Regulating Valves

• Speed control for Variable Frequency Drives (VFDs)

• Control of Electric Actuators

• Proportional Control systems

• Driving various actuators in Process Industries, such as:

  • Oil & Gas

  • Chemicals

  • Pharmaceuticals

  • Power Generation

  • Water & Wastewater Treatment
