Why the TSXAEY1600 Is a Smart Choice for Your Control System
When you are responsible for keeping a production line running, every component in your control system must deliver consistent performance. The Schneider Electric TSXAEY1600 analog input module offers the reliability you need for precise data acquisition in demanding industrial environments. As part of the TSX Micro PLCs series, this module is engineered to integrate seamlessly into existing architectures, reducing the complexity of upgrades and maintenance.
For maintenance engineers, the TSXAEY1600 provides a straightforward path to expand analog input capacity without redesigning the entire control panel. Its standard module format and clear electrical connections simplify installation and troubleshooting, helping you minimize downtime and keep operations moving.
Technical Specifications and Performance
The TSXAEY1600 is built to handle a variety of analog signals, supporting current inputs of 0-20 mA and 4-20 mA, as well as voltage inputs of ±10 V, 0-10 V, 0-5 V, and 1-5 V. With 16 high-level input channels and 12-bit analog-to-digital conversion, this module delivers the resolution needed for accurate monitoring and control.
Measurement error is kept low, at just 0.1% of full scale at 25°C for voltage ranges, ensuring that your process data is trustworthy. The fast read cycle time of 3 ms plus 3 ms per channel used allows for rapid updates in time-critical applications, while the nominal read cycle time of 51 ms provides a stable baseline for standard operations.
Electrical isolation is a key safety feature, with 1000 Vrms isolation between channels and the bus, and equally between channels and ground. This helps protect your PLC and connected sensors from ground loops and voltage transients. The module also includes input overvoltage protection from -15 to 15 V at state 0 and -30 to 30 V at state 1, adding an extra layer of defense against surges.

Applications in Modern Manufacturing
In a typical packaging line, the TSXAEY1600 can monitor multiple analog sensors, such as temperature transmitters and pressure transducers, providing real-time data to the PLC for precise control. The ability to handle both current and voltage signals makes it versatile for retrofitting older machines that use different sensor types.
For a water treatment facility, the module’s 16 channels allow you to connect a wide array of flow meters and level sensors, consolidating data acquisition into a single module. This reduces wiring complexity and simplifies maintenance, as you have fewer components to check when a fault occurs.
In a hypothetical automotive parts assembly scenario, the TSXAEY1600 could be used to monitor torque and position sensors on robotic arms. The fast read cycle time ensures that the control loop receives timely feedback, helping to maintain quality and prevent defects.
Integration with Your Existing System
The TSXAEY1600 is designed for the Modicon Premium automation platform, but it is also compatible with TSX Micro PLCs, making it a flexible option for many control cabinets. The module connects via two SUB-D 25 connectors, which are standard in industrial settings, so you can likely reuse existing cables or easily source new ones.
With a current consumption of only 270 mA at 5 V DC, the module places a minimal load on your PLC’s power supply, leaving headroom for other modules. This is particularly beneficial when you are adding capacity to an existing rack without upgrading the power supply.

Business Value and ROI
Investing in the TSXAEY1600 can reduce your total cost of ownership by minimizing the need for multiple signal conditioners or additional I/O modules. Its high channel count and multi-range input capability mean you can standardize on one module for various signal types, simplifying your spare parts inventory.
The module’s robust design, with an operating temperature range of 0 to 60°C and storage from -25 to 70°C, ensures reliable performance even in harsh environments. This reduces the risk of unexpected failures and the associated costs of unplanned downtime.
