Emerson KJ3223X1-BA1 Analog Input Card - 16-Channel 4-20mA HART Solution

The Emerson KJ3223X1-BA1 (Part Number: 12P2871X022) delivers enterprise-grade analog signal processing for DeltaV distributed control systems. This 16-channel card combines precision 4-20mA current loop measurement with HART digital communication, enabling simultaneous process control and intelligent device diagnostics across pharmaceutical manufacturing, petrochemical refineries, and power generation facilities.

Core Technical Specifications

Input Channels: 16 differential analog inputs
Signal Range: 4-20mA industry standard current loop
Protocol Support: HART communication overlay on all channels
Resolution: 16-bit A/D conversion for ±0.1% accuracy
Update Rate: Configurable from 100ms to 10 seconds per channel
Isolation: 1500V channel-to-backplane galvanic isolation
Operating Range: -40°C to +70°C ambient temperature
Compliance: IEC 61508 SIL 2 certified for safety systems

Industrial Application Scenarios

Engineered for continuous process monitoring in mission-critical environments. Deploy the KJ3223X1-BA1 for temperature transmitter arrays, pressure sensor networks, flow measurement systems, and level detection grids. The HART protocol overlay enables simultaneous 4-20mA process variable transmission and digital device diagnostics without interrupting control loops—essential for predictive maintenance strategies in zero-downtime operations.

Advanced Integration Solutions

This module seamlessly integrates with DeltaV M-series and S-series controllers through the 12P2871X022 CHARM interface. The card's intelligent diagnostics detect open circuits, short circuits, and out-of-range conditions in real time, triggering configurable alarms through the DeltaV control network. Hot-swappable architecture ensures field replacement without system shutdown, while automatic channel calibration maintains measurement integrity across the product lifecycle. The HART multiplexing capability enables asset management and device configuration without additional wiring infrastructure.

Performance Advantages

✓ Dual-layer signal filtering eliminates electrical noise interference in harsh industrial environments
✓ HART multiplexing enables asset management without additional wiring costs
✓ Conformal coating protects against corrosive atmospheres and humidity
✓ Backward compatible with legacy DeltaV infrastructure for seamless upgrades
✓ Certified to IEC 61508 SIL 2 for safety-instrumented systems deployment
