YOKOGAWA SAI143-H53A4D00 Analog Input Module

Description

Product Introduction: YOKOGAWA SAI143-H53A4D00 Analog Input Module (PROFIBUS-DP Communication Type)

Overview

YOKOGAWA SAI143-H53A4D00 is a product of YOKOGAWA Electric Corporation of Japan for its renowned PROSAFE-RS safety instrument system (SIS) or CENTUM VP Distributed control system (DCS). A high-performance and highly reliable analog input (AI) module designed for the platform. The core function of this module is to collect signals from on-site analog sensors (such as temperature, pressure, and flow transmitters) via the PROFIBUS-DP fieldbus protocol, convert them into digital quantities, and transmit them to the upper-level control system for process monitoring, interlock protection, and logical control.

The “H53” in its model number usually indicates that the module complies with the strict HART communication protocol integration requirements, making it an ideal choice for intelligent instrument management in process industries.

Core functions and working principles

1. Signal acquisition
The module provides multiple channels (typically 4 or 8 channels, please refer to the specific manual), and each channel can be independently configured to receive analog signals from field devices.

The supported input signal types are extensive, typically including: 4-20mA (the most commonly used), 0-20mA, 1-5V, thermocouples (T/C), thermal resistors (RTD), etc.

2. Signal Conversion and Processing
It is equipped with a high-precision and high-resolution analog-to-digital converter (ADC) that converts continuous analog signals into precise digital values.

The collected data is processed through engineering unit conversion, linearization (for thermocouples/thermal resistors), filtering and alarm judgment, etc.

3. HART Protocol Integration (Core Features) :
The “H” mark in the model indicates that the module integrates a HART protocol modem.

While transmitting 4-20mA analog signals, digital communication can be carried out with intelligent transmitters that support the HART protocol through the same pair of wires. This means it can:

▪ Remote configuration: Modify the range, unit, damping time and other parameters of the on-site instrument online.

▪ Advanced Diagnosis: Read the equipment status of the transmitter, self-diagnostic information, and alarm information to achieve predictive maintenance.

▪ Calibration Management: Read verification data to reduce unplanned downtime.

4. PROFIBUS-DP Communication:
As a PROFIBUS-DP slave station, it conducts stable and real-time data exchange with the DCS/PLC controller serving as the master station (such as YOKOGAWA’s AFV70D DP master station module) through the high-speed DP bus.

5. Condition Monitoring and Safety
The module continuously performs self-diagnosis, capable of detecting faults such as open circuits, short circuits, and signal over-limits, and uploads the status information to the control system to ensure the reliability of the measurement values. This is crucial for the safety instrumente system (SIS).

SAI143-H53

Main features and advantages

• Extremely high reliability and availability: Drawing on Yokogawa Electric’s profound accumulation in the process industry, it is designed for 7×24-hour continuous operation with an extremely long mean time between failures (MTBF), meeting the demanding requirements of industrial environments.

• Powerful HART integration capability: Without the need for additional HART controllers or interface devices, on-site intelligent instruments can be centrally configured and managed, significantly simplifying debugging and maintenance work and reducing life cycle costs.

• Flexible configuration and compatibility: Each input channel can be independently configured for different signal types, providing great application flexibility. Seamlessly integrated with YOKOGAWA’s PROSAFE-RS and CENTUM VP systems.

• Modularization and hot plugging: It usually supports online hot plugging (where permitted), allowing modules to be replaced without stopping the system, maximizing system availability.

• Compliant with international standards: The design and manufacture comply with international standards such as PROFIBUS and HART, and meet the safety level requirements of SIL 2/SIL 3 (in the PROSAFE-RS system).
