Schneider Electric TSXAEY420 Analog Input Module for TSX PLC

Product Overview

The Schneider Electric TSXAEY420 is a precision analog input module developed for Modicon TSX Series 7 PLC platforms. It converts industrial analog signals into high-resolution digital values for reliable process monitoring and control.

Moreover, this module supports demanding environments where signal stability and measurement accuracy remain critical. Its robust design reflects Schneider Electric’s long experience with mission-critical automation systems.

In addition, refurbished TSXAEY420 modules allow plants to maintain existing TSX infrastructures without disruptive system upgrades. Therefore, they provide a cost-effective solution for extending legacy PLC lifecycles.

Functional Highlights

The TSXAEY420 provides four independent analog input channels with true 16-bit resolution. Moreover, it supports 0–20 mA current signals commonly used in industrial instrumentation.

In addition, electrical isolation protects control systems from noise, ground loops, and transient disturbances. Therefore, signal integrity remains stable in harsh electrical environments.

Integrated diagnostics help detect abnormal signal conditions early during operation. Consequently, maintenance teams can respond proactively and reduce unexpected downtime.
