Product Description

Overview

The SAV144-S33 is a high-precision Analog Input Module from Yokogawa, designed for use with CENTUM VP and ProSafe-RS systems. This module provides 16 isolated input channels to interface with field sensors and transmitters, converting analog signals into digital data for control or safety processing. The -S33 variant features G3 conformal coating, ensuring robust protection in harsh industrial environments.

The module supports dual-redundant operation with compatible terminal boards, providing enhanced reliability for critical process control and safety applications.

Key Features

High-Density Input Capability

  • 16 analog input channels in a single compact module

  • Reduces control cabinet footprint and hardware cost per point

Versatile Signal Compatibility

  • Accepts standard industrial signals: 4–20 mA DC or 1–5 V DC

  • Can be used to monitor pressure, flow, temperature, and level transmitters

High Accuracy and Stability

  • Advanced A/D conversion ensures precise measurement and low noise

  • Excellent temperature stability and interference rejection for reliable data

Built-In Diagnostics

  • Channel monitoring detects open-circuit or short-circuit conditions

  • Front-panel LEDs (STATUS, HRDY) indicate module health and communication status

Environmental Hardening

  • G3 Conformal Coating protects against moisture, dust, and corrosive gases such as H₂S and SO₂

  • Suitable for offshore platforms, chemical plants, and high-humidity environments

Flexible Connection Options

  • Pressure clamp terminal, MIL cable, or dedicated signal cable (KS1)

  • Module weight: 0.24–0.29 kg depending on connection type
