Product Description

The KJ3002X1-BF1 (Assembly Number 12P0554X122) is a high-performance Resistance Temperature Detector (RTD) input module integrated into the Emerson DeltaV M-Series I/O family. This module is engineered to interface directly with 2-wire, 3-wire, or 4-wire RTD sensors, converting low-level resistance signals into digital process variables. It features high-resolution analog-to-digital conversion and onboard cold-junction compensation to maintain measurement accuracy across fluctuating ambient temperatures.

Technical Specifications

Specification Details
Channel Density 8 independent RTD input channels
Input Type Support Pt100, Pt200, Pt500, Ni100, Ni120, and Cu10 sensors
Resistance Range 0 to 2000 Ohms (covering standard industrial ranges)
Accuracy ±0.1% of span at calibrated temperature
Resolution 16-bit A/D converter performance
Common Mode Rejection >100 dB at 50/60 Hz
Local Bus Power 12V DC at 150 mA maximum
Physical Dimensions 4.4 cm x 10.2 cm x 10.8 cm

Operational Integration

The KJ3002X1-BF1 is designed for high-availability environments, supporting online removal and insertion (hot-swapping) under power. It automatically performs self-diagnostics and reports sensor burnout or short-circuit faults to the DeltaV controller, reducing troubleshooting time in critical thermal loops.

Engineering FAQ

Q: Does the KJ3002X1-BF1 support lead-wire resistance compensation?
A: Yes, for 3-wire and 4-wire RTD configurations, the module actively compensates for lead-wire resistance to ensure that cable length does not introduce measurement error.
