Emerson KJ3223X1-BA1 – DeltaV™ Analog Input Module | DeltaV™ Series Platform
Engineering Background
The Emerson KJ3223X1-BA1 (part number 12P2871X022) is a field-proven analog input module designed for the Emerson DeltaV™ Distributed Control System (DCS) platform. Engineered to meet the rigorous demands of continuous process industries, this module delivers high-accuracy signal acquisition with native DeltaV integration, eliminating the need for external signal conditioning in most applications.
Product Positioning
Targeted at procurement engineers and MRO buyers in oil & gas, chemical, power generation, and pharmaceutical sectors, the KJ3223X1-BA1 serves as a direct replacement or expansion card within existing DeltaV controller nodes. Its plug-and-play compatibility with DeltaV I/O subsystems minimizes commissioning time and reduces total cost of ownership.

System Architecture & Signal Flow
The KJ3223X1-BA1 mounts directly onto a DeltaV I/O carrier (8-slot or 4-slot) and communicates over the DeltaV I/O bus to the controller node (MD, MD Plus, or MQ series). Field wiring terminates at the carrier’s marshalling terminals. Signal conditioning, scaling, and HART pass-through (where applicable) are handled within the DeltaV system software, providing a seamless engineering workflow from field device to HMI historian.
Recommended pairing: DeltaV MD/MQ Controller + KJ3223X1-BA1 I/O Card + DeltaV Operate HMI for a complete analog input loop.

Technical FAQ
Q: Is KJ3223X1-BA1 compatible with DeltaV S-series controllers?
A: The KJ3223X1-BA1 is designed for the DeltaV traditional I/O architecture. Compatibility with DeltaV S-series (CHARM-based) requires an I/O carrier adapter — consult your DeltaV system engineer.
Q: Can this module be used in SIL 2 safety loops?
A: Only when integrated within a certified DeltaV SIS architecture. Standalone use does not confer SIL rating. Verify with your functional safety engineer.
Q: What firmware version is installed?
A: Firmware version is documented per unit upon request. Contact us with your serial number requirement before ordering.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. CoC is available upon request at no additional charge.
Q: What is the lead time for bulk orders (5+ units)?
A: Bulk availability is subject to current stock. Submit an RFQ for priority allocation and volume pricing.
