EMERSON KJ3002X1-BF1 12P1732X072 – 12-Channel RTD Input Module | DeltaV Series
Engineering Background
The KJ3002X1-BF1 (assembly part 12P1732X072) is Emerson’s dedicated Resistance Temperature Detector (RTD) input card for the DeltaV distributed control system platform. Designed for precision temperature measurement in continuous process environments, this module interfaces directly with the DeltaV I/O subsystem via the standard DeltaV carrier/marshalling architecture, eliminating the need for external signal conditioning hardware.
Product Positioning
This module is the preferred choice for process engineers specifying temperature loops in refining, petrochemical, pharmaceutical, and power generation facilities where DeltaV is the incumbent DCS. Its 12-channel density reduces cabinet footprint and wiring cost compared to legacy 8-channel predecessors, while maintaining full backward compatibility with existing DeltaV controller firmware.

Engineering Advantages
- 12-Channel Density – Reduces I/O carrier slots required by 33 % vs. 8-channel modules, lowering BOM and cabinet cost
- Universal RTD Wiring – Supports 2-, 3-, and 4-wire configurations per channel; no jumper changes required — set via DeltaV Control Studio software
- On-board Cold-Junction Compensation – Internal reference resistor eliminates external compensation hardware
- Plug-and-Play DeltaV Integration – Auto-recognized by DeltaV controller; no manual address DIP switches
- Diagnostic Transparency – Per-channel open-circuit, short-circuit, and out-of-range diagnostics surfaced natively in DeltaV Operate
- Hot-Swap Capable – Module can be replaced under power with appropriate DeltaV carrier (check carrier datasheet for confirmation)
System Architecture & Signal Flow
The KJ3002X1-BF1 mounts onto a standard DeltaV 8-slot or 12-slot I/O carrier. Field RTD wires terminate at the carrier’s marshalling terminals. The module samples each RTD channel sequentially using an internal precision current source and 24-bit sigma-delta ADC. Digitized values are transmitted over the DeltaV I/O bus to the assigned controller (MD, MD Plus, or MQ series) at the configured scan rate (default 100 ms). The controller publishes the EU-converted temperature values to the DeltaV data highway for use in PID function blocks, historian, and operator displays.

Technical FAQ
Q: Is KJ3002X1-BF1 compatible with DeltaV S-series controllers?
A: Yes. The module is compatible with all DeltaV controller generations (MD, MD Plus, MQ, S-series) running firmware v7.x and above.
Q: Can I mix RTD types (e.g., Pt100 and Ni100) on the same module?
A: Yes. Each channel is configured independently in DeltaV Control Studio; different RTD types can coexist on the same card.
Q: What is the maximum cable length for RTD field wiring?
A: Emerson recommends ≤ 300 m for 3-wire Pt100 at 0.5 mm² conductor cross-section. Use 4-wire configuration for longer runs to eliminate lead resistance error.
Q: Does this module support HART or Foundation Fieldbus?
A: No. KJ3002X1-BF1 is a conventional hardwired RTD input module. For HART RTD transmitters, use the KJ3001X1 AI module series.
Q: What is the scan rate?
A: Default 100 ms per module (all 12 channels). Configurable in DeltaV Control Studio down to the controller’s minimum scan period.
Q: Is a Certificate of Conformance available?
A: Yes, upon request for orders ≥ 2 units. Contact [email protected].
