SAI533-H53/A4D00 | Yokogawa | 32-Channel Analog Input Module

Analog Input Module

Product Description

Product Overview

YOKOGAWA SAI533-H53/A4D00 is a high-density Analog Input (AI) module designed for the CENTUM VP Field I/O (FIO) system. The module provides reliable acquisition of multiple analog process signals and supports integration with HART-enabled field devices.

With 32 input channels in a compact form factor, this module is intended for large-scale process automation systems where signal density, diagnostic capability, and long-term stability are essential.

Functional Description

The SAI533-H53/A4D00 collects analog field signals and transmits them to the control system through Yokogawa’s ESB / ER bus architecture via FIO node units. It supports both current and voltage inputs and includes advanced diagnostics for early detection of wiring faults, signal abnormalities, and module status issues.

Channel isolation and system isolation are implemented to ensure stable operation in electrically noisy industrial environments.
