Controller Module SE4003S2

SE4003S2 Input/Output Module

Analog Module SE4003S2

Core Functions and Positioning

Product Positioning: The core analog input module of Emerson DeltaV distributed control system, used to acquire analog signals from industrial sites (such as 4-20mA current, temperature, pressure, liquid level, flow rate, etc.), supporting HART protocol for intelligent sensor communication and remote diagnostics.

Modular Design: Offers 8-channel (e.g., SE4003S2B1) and 16-channel (e.g., SE4003S2B11) versions to adapt to different scales of automation needs, and supports redundant configurations (e.g., the SE4033S2B1 redundant card) to improve system reliability.

The SE4003S2 is an analog input card series in Emerson’s DeltaV system, mainly used in industrial automation control systems to acquire analog signals such as temperature, pressure, liquid level, and flow rate.

Different Functional Features:

SE4003S2B6: 16-channel analog input card, supports 4-20 mA current signals and HART protocol, uses 48-pin AI Mass terminals, suitable for high-density signal acquisition scenarios. Estimated price: approximately 6000 RMB (per card), discounts available for bulk purchases.

SE4003S2B11: 16-channel analog input Plus card, also supports 4-20 mA/HART, but equipped with a 48-pin AI Mass terminal and compatible with 2/4-wire devices, supporting redundant design to improve system reliability.

SE4003S2B1: 8-channel analog input card, supports 4-20 mA/HART, uses 8-channel terminal blocks, suitable for small to medium-sized systems.

Accuracy and Resolution: Accuracy up to 0.25% of full scale, resolution 12-16 bits, supports linearization error compensation (±0.003% of full scale).

HART Protocol: Integrated HART communication capability, can read smart sensor parameters and achieve remote configuration.

Signal Type: Primarily 4-20 mA current signal, compatible with HART protocol (supports device diagnostics and parameter configuration).

Channel Configuration: 8/16 channels optional, some models support redundant channel design (e.g., SE4003S2B5).

Terminal Types: Includes 48-pin Mass terminals, 16/24-pin I/O terminals, fuse terminals, etc., adaptable to various wiring requirements.

Environmental Adaptability: Operating temperature -40~70℃, vibration resistant (10g sine wave), dust and water resistant (IP20), meets ISA-S71.04 G3 pollution standard.

Electrical Characteristics: High input impedance, signal isolation design (e.g., optical isolation) ensures interference immunity.

Electrical and Physical Characteristics:

Power Requirements: 12V DC local bus power supply, typical power consumption 100mA, maximum 150mA; maximum 300mA@24V DC for field circuits.

Environmental Adaptability: Operating temperature -40°C to 70°C, humidity 5%-95% non-condensing, ISA-S71.04 G3 pollution certification, vibration resistant (10g sine wave/11ms) and shock resistant.

Isolation and Protection: Input channel isolation voltage 2200V RMS, channel-to-system isolation 3700V RMS, built-in overcurrent protection (e.g., 2A fuse option).

Interfaces and Compatibility:

Terminal Blocks: 48-pin AI Mass terminal blocks (16-channel version) or 16/24-pin large-scale terminal blocks, supporting thermocouple/RTD signal input (terminal module required).

Communication Protocols: Compatible with industrial protocols such as Modbus and Profibus, in addition to HART, supporting seamless integration with DeltaV systems.

Redundancy Design: Optional redundancy configuration (e.g., SE4033S2B1), improving system availability through dual-card hot backup.

Application Scenarios and Advantages:

Industry Applications: Widely used in petrochemical, power, pharmaceutical, water treatment, and metallurgical industries for process control, mass production, energy management, and equipment condition monitoring.

System Compatibility: Compatible with DeltaV M-series/S-series I/O cards, supports modular expansion (such as thermocouple/RTD modules, digital modules), and can be upgraded online to the SX controller architecture.

Installation and Maintenance:

Installation Specifications: Follow the DeltaV system installation manual. Supports rack mounting. Ensure proper grounding and provide sufficient space for heat dissipation (at least 50mm recommended).

Maintenance Ease: Modular design supports hot-swapping. Built-in self-diagnostic functions (such as channel fault alarms and calibration data storage) simplify troubleshooting and maintenance.

Expansion Capabilities and Upgrade Path:

Expansion Modules: Supports compatible terminal modules (such as the SE4003S6B1 RTD module and SE4003S4B1 thermocouple module) to achieve multi-type signal acquisition.

System Upgrade: When upgrading from an SQ controller to an SX controller, the configuration and hardware design can be retained, reducing upgrade costs; compatible with the DeltaV CHARM I/O subsystem, supports Zone 2 installation (compliant with ATEX/IECEx explosion-proof standards).

In summary, the EMERSON SE4003S2 series analog input cards, with their high-precision signal processing, wide environmental adaptability, modular design, and strong system compatibility, have become a reliable data acquisition solution in the field of industrial automation. They are suitable for flexible deployment from small devices to large factories, supporting efficient production management and intelligent upgrades.
