Description

The Yokogawa AAR145-S00 S1 is a high-density, 16-channel analog input module designed for the CENTUM series control systems. This module is specifically engineered to process RTD (Resistance Temperature Detector) and Potentiometer (POT) signals, providing isolated inputs for reliable data acquisition in industrial process control environments.

Features

• 16 isolated input channels for enhanced signal integrity.
• Supports JIS C1604:1997 and IEC751:1995 Pt100 (3-wire) RTD inputs.
• Configurable for Potentiometer inputs with total resistance ranges from 100 Ohm to 10 kOhm.
• Individual channel configuration for RTD or POT signal types.
• Integrated burn-out detection with configurable UP/DOWN settings.
• High withstanding voltage isolation between channels and system.

Applications

This module is widely used in process automation systems where precise temperature monitoring or position feedback is required. Typical applications include thermal management systems, valve position monitoring, and critical process measurement loops within the Yokogawa CENTUM distributed control system architecture.

Technical Specifications

Installation Guidelines

• Ensure the control system is powered down before inserting or removing the module from the rack.
• Handle the module using proper ESD (Electrostatic Discharge) protection practices to prevent damage to internal circuitry.
• Verify that all field wiring is connected via the specified dedicated cabling (KS8/AKB335) to maintain signal isolation and accuracy.
• Ensure the module is fully seated in the backplane to ensure proper electrical contact.
• Keep signal wiring separated from high-voltage power cables to minimize EMI/RFI interference.

FAQ

What type of RTD sensors are supported by the AAR145-S00?

The module supports 3-wire Pt100 RTDs compliant with JIS C1604:1997 and IEC751:1995 standards.

Can I mix RTD and Potentiometer inputs on the same module?

Yes, the AAR145 allows for individual selection of RTD or POT signal types for each of the 16 channels.

What is the required cable for this module?

The module requires the dedicated KS8/AKB335 cable for external field connections.
