Product Overview

The Yokogawa SDV144-S13/B4D00 serves as a high-density analog voltage acquisition interface for the CENTUM VP and ProSafe-RS control platforms. This module captures 16 channels of isolated voltage signals from field instruments, providing a high-fidelity data bridge between field sensors and the central control processor. Engineered for the Field I/O (FIO) family, the SDV144-S13 excels in demanding oil & gas, chemical, and power generation environments where rapid signal processing (10ms update) and robust channel-to-channel isolation are mandatory for operational safety.

Condition: 100% Brand New Original.

Part Number Breakdown: SDV144 Series

Yokogawa utilizes specific alphanumeric coding to define the hardware revision and interface specifications of the SDV144 series.

• SDV144: Isolated Analog Voltage Input Module (16-Channel).

• -S: Standard type for FIO systems.

• 1: Style code (indicates specific hardware generation and component baseline).

• 3: Enhanced durability revision for broader industrial compatibility.

• B4D00: Equipped with a dual-redundant pressure clamp terminal block for direct wiring (without surge absorber).

Technical Specifications

The SDV144-S13/B4D00 combines 12-bit precision with extreme isolation to protect sensitive control logic.

Engineering Advantages

• High-Speed Control Loop Support: The 10ms update period enables the Distributed Control System (DCS) to track process variables in near real-time. This speed proves vital for surge control, pressure regulation, and high-speed safety interlocks.

• Ground Loop Elimination: Full channel-to-channel isolation suppresses electrical noise and prevents ground potential differences from contaminating signal integrity. This architecture ensures that a single field device fault does not disrupt the remaining 15 signal loops.

• Compact Redundant Wiring: The /B4D00 option integrates dual-redundant pressure clamp terminals directly into the module footprint. This design saves significant cabinet space compared to external marshaling panels and provides a vibration-proof connection that resists the mechanical stress of industrial environments.

• Advanced Module Diagnostics: The module executes continuous internal self-checks. It monitors input signal health and internal hardware status, reporting faults to the Human Interface Station (HIS) immediately to facilitate proactive maintenance and prevent unplanned shutdowns.

FAQs

Q: Can the SDV144-S13/B4D00 handle 4-20 mA current signals?

A: Yes. Although natively a voltage input module (1-5V), you can monitor standard 4-20 mA current loops by installing a precision 250-ohm shunt resistor across the terminal inputs to convert the current into a compatible voltage signal.

Q: What is the primary benefit of the /B4D00 terminal block?

A: The /B4D00 option provides a dual-redundant pressure clamp interface. This allows you to wire field devices in a redundant configuration directly to the module, ensuring continuous data acquisition even during a single-path wiring failure.

Q: Is the SDV144-S13 compatible with legacy CS 3000 systems?

A: Yes. As part of the Yokogawa FIO family, the SDV144-S13 maintains backward compatibility with CENTUM CS 3000 systems while being fully optimized for the latest CENTUM VP and ProSafe-RS hardware.

Q: Does this module require an external power supply for the field sensors?

A: The SDV144-S13 focuses on signal acquisition. While it processes the incoming voltage, your field transmitters typically require a separate 24V DC loop power supply, unless they are self-powered voltage sources.
