Product Description

Precision Analog Data Acquisition

The Emerson DeltaV KJ3222X1-BA1 (Part Number 12P2532X092) is a high-performance Analog Input (AI) module belonging to the DeltaV M-Series Traditional I/O family. This Series 2 card is engineered to interface with 8 channels of 4–20 mA field transmitters. Beyond simple current measurement, it features integrated HART (Highway Addressable Remote Transducer) protocol support. This allows system engineers to pass digital diagnostic data and configuration parameters from smart field instruments directly to the DeltaV DCS, enabling proactive asset management and reduced maintenance downtime.

Industrial-Grade Reliability and Compliance

Built for the most demanding process environments, the KJ3222X1-BA1 is G3-rated according to ISA-S71.04, providing essential protection against corrosive airborne contaminants commonly found in chemical and refinery settings. The module is hazardous area certified (ATEX/IECEx/FM), making it suitable for deployment in explosive atmospheres. Each channel provides galvanic isolation to ensure signal integrity and protect the system bus from field-side electrical interference. With a wide operating temperature range of –40 °C to +70 °C, it delivers consistent, high-accuracy performance across extreme climate variations.

Detailed Technical Specifications

Industrial Application Scenarios

• Refinery Process Monitoring: Capturing high-precision pressure and temperature data from HART-enabled transmitters.

• Chemical Dosing: Monitoring flow rates in batch processing where smart instrument diagnostics are critical for quality control.

• Hazardous Area Deployment: Utilizing ATEX/IECEx certifications for safe signal acquisition in volatile gas environments.

• Predictive Maintenance: Leveraging HART data to monitor transmitter health and sensor drift before failure occurs.

FAQ: Frequently Asked Questions

• Q: Does this module provide power to the field transmitters?Ans: Yes, the KJ3222X1-BA1 provides 24 VDC field circuit power at 30 mA per channel, sufficient for powering standard 2-wire 4–20 mA current loop transmitters.

• Q: Can I use this card without HART-enabled instruments?Ans: Absolutely. While optimized for HART, the KJ3222X1-BA1 functions as a high-accuracy standard 4–20 mA analog input card for any traditional analog device.

• Q: What is the significance of the G3 rating?Ans: The G3 rating indicates the card's ability to operate in "harsh" environments with high levels of sulfur and chlorine, common in paper mills and petrochemical plants.
