The VE4003S2B3 Analog Input Card is a critical I/O component of Emerson DeltaV Distributed Control System (DCS). With part numbers including 12P2532X162-233A and KJ3222X1-BA1, it comes standard with a 4-wire I/O terminal block (e.g., KJ4001X1-CC1). Supporting 8 independent 4-20mA analog input channels and natively compatible with the HART protocol, this card can simultaneously acquire process variables as well as diagnostic and configuration data from intelligent instruments. It balances signal accuracy and equipment asset management, making it suitable for both critical and general monitoring loops in process industries such as chemicals, oil and gas, power generation, and pharmaceuticals.

Technical Specifications

Channel Configuration: 8 channels, 4-wire system, with isolation between channels.

Signal Type: 4-20mA DC, compatible with HART 5/7 protocols.

Accuracy Specifications: ±0.05% of full scale (typical value), 16-bit A/D conversion, and low temperature drift (±0.01% of full scale/°C).

Isolation Performance: Channel-to-channel and channel-to-backplane isolation, with an isolation voltage of 1500V DC and strong resistance to common-mode interference.

Power Supply and Wiring: 24V DC power supply on the field side, standard terminal block wiring, and supports online hot swapping.

Fault Diagnosis: Detection of wire breakage, short circuit, overcurrent and over-range conditions, with support for channel-level status reporting.

Environmental Adaptability: Operating temperature ranges from 0–60°C, storage temperature ranges from -40–85°C; relative humidity ranges from 5%–95% (non-condensing); compliant with CE, UL, CSA and other industrial certifications.

Functionalities & Advantages

Deep HART Integration: Each channel features independent HART communication, supporting remote configuration, calibration, diagnosis and parameter uploading of instruments. Equipment maintenance can be completed without interrupting ongoing processes, minimizing downtime risks.

High Precision & Stability: Equipped with 16-bit A/D conversion and a low-noise front end, the card ensures a measurement accuracy of ±0.05% of full scale, combined with low temperature drift. It is suitable for wide-temperature industrial environments and guarantees data consistency.

Full Isolation & High Reliability: Dual isolation between channels and between channels and the system effectively suppresses ground loops and common-mode interference. Supporting hot swapping and online replacement, it works with the redundant architecture of DeltaV systems to enhance overall system availability.

Comprehensive Fault Detection: Real-time monitoring of line and signal anomalies such as wire breakage, short circuit, overcurrent and over-range conditions. Status signals are uploaded to the controller for quick fault localization, reducing maintenance time.

Engineering Compatibility: Fully compatible with DeltaV system software, it supports channel-level parameter configuration (including range, filtering and alarm threshold settings). The terminal block follows standard wiring specifications and is suitable for installation in standard cabinets. No rewiring is required for engineering modifications, lowering commissioning costs.

Application Scenarios

Process Variable Acquisition: Connects to 4-20mA/HART transmitters for pressure, differential pressure, liquid level and temperature, supporting closed-loop control and data logging.

Intelligent Device Management: Retrieves diagnostic data from valve positioners, flow computers and other equipment via HART, enabling predictive maintenance.

Redundant & Critical Loops: Compatible with the redundant architecture of DeltaV controllers, it is ideal for signal acquisition in safety-critical control loops.

Legacy System Upgrade: As a traditional M-Series I/O module, it is fully compatible with DeltaV systems and can be used for I/O expansion or replacement in existing DCS installations.
