EMERSON KJ3002X1-BF1 – RTD Multi-Channel Input Module | DeltaV DCS Platform
Engineering Background
The KJ3002X1-BF1 (alternate part number 12P1732X082) is a factory-certified RTD (Resistance Temperature Detector) input module designed exclusively for Emerson’s DeltaV distributed control system. As a core I/O card within the DeltaV S-series and M-series controller chassis, it provides high-resolution, multi-channel temperature measurement directly on the process bus — eliminating the need for external signal conditioners and reducing wiring complexity in large-scale installations.
Product Positioning
Procurement engineers specifying temperature measurement for refinery, chemical, or power generation applications rely on the KJ3002X1-BF1 for its native DeltaV integration, HART-transparent architecture, and proven long-term availability. Konmask.com supplies this module as a tested, traceable surplus unit — ideal for system expansions, emergency replacements, and lifecycle extension projects where lead times on new OEM stock are unacceptable.

- Hot-Swap Capable: Module can be replaced under power in redundant controller configurations — zero process downtime during maintenance
- Long Production History: Proven in DeltaV installations since the late 1990s; extensive field data and community knowledge base available
System Architecture & Signal Flow
The KJ3002X1-BF1 mounts directly into a DeltaV I/O carrier (8-slot or 4-slot). Field RTD sensors connect via marshalling cabinet or directly to the module’s terminal block. The module performs on-board analog-to-digital conversion and linearization, then transmits engineering-unit values over the DeltaV I/O bus to the controller (MD, MD Plus, or MQ). Within DeltaV Explorer, each channel appears as a discrete AI function block parameter, addressable in control modules and SIS logic.
Typical signal path: RTD sensor → field junction box → marshalling cabinet → KJ3002X1-BF1 terminal block → I/O bus → DeltaV controller → DeltaV Operate HMI / historian

Technical FAQ
Q: Is KJ3002X1-BF1 compatible with DeltaV version 14.x and later?
A: Yes. The module is recognized by DeltaV v7.x through v15.x. Firmware updates are managed automatically by the DeltaV controller upon insertion.
Q: Can I mix RTD and thermocouple inputs on the same I/O carrier?
A: Yes. DeltaV I/O carriers support mixed module types. The KJ3002X1-BF1 occupies one slot; thermocouple modules (e.g., KJ3001X1) can occupy adjacent slots without interference.
Q: What is the difference between KJ3002X1-BF1 and 12P1732X082?
A: These are the same physical module. KJ3002X1-BF1 is the Emerson catalog part number; 12P1732X082 is the internal manufacturing/revision code printed on the module label. Both reference the same hardware revision.
Q: Does this module support HART pass-through?
A: No. RTD sensors are passive resistive devices and do not carry HART signals. HART pass-through is applicable to 4–20 mA AI/AO modules only.
Q: What happens if one RTD channel fails?
A: The module reports a channel-level fault alarm in DeltaV and continues normal operation on all remaining channels. No module-level reset or replacement is required for a single-channel fault.
Q: Can Konmask provide a test report before shipment?
A: Yes. A basic functional test report (power-on, channel enumeration, firmware version) can be provided upon request. Contact support@konmask.com to arrange.
