Schneider Electric 140ARI03000 RTD Input Module Quantum PLC

Product Description

The 140ARI03000 by Schneider Electric is an 8-channel RTD input module developed for the Modicon Quantum automation platform. It is engineered to acquire precise temperature data from resistance temperature detectors and convert it into digital values for PLC processing. The module integrates signal isolation and filtering to ensure stable measurements in electrically noisy industrial environments.

Although the 140ARI03000 has been phased out since September 2022, it remains in use across many legacy Quantum installations. Schneider Electric recommends migration to the BMXART0814 module from the Modicon X80 series for new deployments or system upgrades.

FAQ

Is the 140ARI03000 still available for purchase? This model is discontinued. It may still be sourced through surplus or third-party suppliers, but availability is limited.

Can this module be directly replaced with BMXART0814? No. The BMXART0814 belongs to the Modicon X80 series and is not directly interchangeable with Quantum modules. System migration or adaptation is required.

What types of RTD sensors are supported? The module is compatible with common RTD elements such as Pt100 and Pt1000, depending on configuration.
