Product Description

Overview

The S9649FA is a 16-channel Analog Input/Output Module engineered for use in Yokogawa CENTUM VP and ProSafe-RS distributed control systems. This module ensures accurate and reliable signal conversion between analog field instruments and the digital control network, supporting critical process measurements such as pressure, temperature, and flow.

Performance and Features

Versatile Analog Signal Handling

• Supports high-precision 4–20 mA input/output signals with 16-bit resolution for accurate data acquisition.

• Dual-mode operation allows configuration as either input or output, minimizing the variety of spare parts needed.

Safety and System Integrity

• Built-in self-diagnostics continuously monitor internal circuitry and detect issues such as wire breaks or loop failures.

• High-level galvanic isolation between field circuits and the system bus prevents ground loops and protects against electrical interference.

Rugged Industrial Design

• Hot-swappable for maintenance without system downtime.

• G3 conformal coating offers protection against corrosive gases like H₂S and SO₂.

• Compact form factor maximizes I/O density in control cabinets.

Ease of Installation

• Pressure-clamp terminals simplify wiring and ensure secure connections in high-vibration environments.

• Baseplate-mounted design compatible with the S9000 series for modular deployment.

Technical Specifications
