VE4003S6B1 DeltaV | KJ3002X1-BF1 M-Series RTD Module

Product Details

Product Overview

The Emerson VE4003S6B1 (Alternate Part Numbers: KJ3002X1-BF1, 12P1732X082) is a high-precision 8-Channel RTD/Ohm Analog Input Card designed for the DeltaV M-series Distributed Control System (DCS). This module specializes in converting resistance signals from Resistance Temperature Detectors (RTDs) and direct Ohm sources into digital temperature data for the DeltaV controller. By providing localized signal conditioning and A/D conversion at the I/O level, the VE4003S6B1 ensures accurate temperature monitoring for critical process equipment like heat exchangers, reactors, and bearing housings.

Part Number Breakdown

• VE4003S6B1: System part number for the RTD/Ohm Input Module assembly.

• KJ3002X1-BF1: Manufacturing hardware identification code.

• 12P1732X082: Internal Emerson component reference number.

Technical Specifications

Engineering Advantages

• High-Resolution Thermal Acquisition: The module utilizes 16-bit A/D conversion to capture microscopic changes in resistance. This high resolution translates to precise temperature readings, allowing the DeltaV system to maintain tight control over temperature-sensitive chemical reactions.

• Built-in Linearization: The VE4003S6B1 automatically linearizes standard RTD curves (such as Pt100) within the module hardware. This offloads the computational burden from the main CPU and ensures that the controller receives accurate, scaled engineering units ($^{\circ}\text{C}$ or $^{\circ}\text{F}$) instantly.

• Advanced Lead-Wire Compensation: The card supports 2-wire, 3-wire, and 4-wire RTD configurations. It automatically compensates for the resistance of the field wiring, eliminating measurement offsets caused by long cable runs between the sensor and the control cabinet.

• System Integrity through Isolation: Galvanic isolation between the field channels and the DeltaV LocalBus prevents electrical noise or ground faults in the field from damaging the controller. This architecture ensures that a single failed RTD sensor does not impact the entire I/O rack.

• Modular Hot-Swappability: The M-series design permits the removal and replacement of the VE4003S6B1 while the system remains powered. This "Plug-and-Play" capability ensures that maintenance teams can update or repair temperature loops without affecting adjacent process monitoring points.

FAQs

Q1: Is the VE4003S6B1 still available if the manufacturer discontinued it?

A1: Yes. While officially discontinued by the manufacturer, we maintain stock of 100% Brand New and Original units. These modules are factory-sealed and ready for immediate deployment in your existing M-series racks.

Q2: Which RTD types does this card support?

A2: The VE4003S6B1 supports common industrial RTDs including Pt100 (Platinum 100 Ohm), Pt1000, Cu10 (Copper), and various Nickel types. You can configure each of the 8 channels independently via the DeltaV Explorer software.

Q3: Can I use this module to measure simple resistance (Ohms) instead of temperature?

A3: Absolutely. The module functions as a high-precision Ohmmeter. You can configure channels to report raw resistance values (up to 2000 Ohms), making it suitable for position sensors or other resistive transducers.

Q4: Does this card require a specific terminal block?

A4: Yes. The VE4003S6B1 requires a standard M-series I/O terminal block. Depending on your wiring preference, you can use either the mass terminal block or the individual screw terminal block for 3-wire or 4-wire RTD connections.
