Introduction
When temperature measurement drift or signal noise threatens process accuracy, the Schneider TSXAEY1614 analog input module delivers reliable, high-resolution data. Part of the TSX Micro PLC series, this module provides 16 high-level input channels with 16-bit analog-to-digital conversion, ensuring precise monitoring for demanding industrial applications.
Technical Specifications Breakdown
The TSXAEY1614 supports a wide range of thermocouple types—B, E, J, K, L, N, R, S, T, and U—as well as voltage inputs of +/- 80 mV. This flexibility allows engineers to standardize on one module for multiple sensor types, reducing inventory complexity. The nominal read cycle time of 70 ms per channel enables timely data acquisition for control loops. Measurement error varies by thermocouple type; for example, thermocouple E exhibits an error of 0.8 °C at 25 °C, while thermocouple R shows 2.1 °C at 25 °C. The module provides 1000 Vrms isolation between channels and bus, and 1000 Vrms between channels and ground, protecting sensitive electronics from ground loops and transient surges. Common mode voltage handling reaches 250 V AC or 280 V AC between channels, and 250 V DC between channels and earth, ensuring reliable operation in electrically noisy environments.
Industry Applications
In chemical processing plants, the TSXAEY1614 monitors reactor temperatures using thermocouple types J or K, with the 16-bit resolution capturing subtle thermal changes that affect yield. For power generation facilities, the module measures exhaust gas temperatures with type N thermocouples, while the 1000 Vrms isolation prevents interference from high-voltage switchgear. The +/- 80 mV voltage input capability also suits strain gauge or pressure transducer signals, making the module a versatile choice for multi-sensor skids.
Installation & Setup Guidance
Connect field wiring using the two SUB-D 25 connectors provided. Ensure that thermocouple extension wires match the thermocouple type to avoid measurement errors. For voltage inputs, use shielded twisted-pair cable and ground the shield at one end only. The module operates within 0 to 60 °C and 10 to 95% relative humidity without condensation. Mount the module in a standard format slot of the TSX Micro rack, and verify that the 5 V DC supply can deliver the required 300 mA.
Maintenance & Reliability
Periodically inspect the SUB-D connectors for corrosion or loose pins, especially in humid environments. The module's IP20 protection degree means it should be installed in a clean, dry enclosure. Check that the ambient temperature stays within 0 to 60 °C to maintain specified accuracy. The module's robust isolation reduces wear from electrical stress, contributing to long service life.
Compatibility & Integration
The TSXAEY1614 integrates seamlessly with Schneider Electric's TSX Micro PLC platform. It is compatible with Modicon Premium automation platforms and supports standard programming tools. The module's CE marking and certifications from DNV, RMRS, LR, ABS, RINA, BV, and GL confirm its suitability for marine and industrial applications.
Selection Guide & Purchasing Advice
Before ordering, verify that your TSX Micro PLC base supports the module format and that your power supply can provide 300 mA at 5 V DC.

Troubleshooting & Common Issues
If readings appear erratic, check thermocouple wiring for open circuits or reversed polarity. Verify that the input overvoltage protection range (-15 to 15 V at state 0, -30 to 30 V at state 1) is not exceeded. If the module fails to communicate, inspect the SUB-D connectors for bent pins and ensure the PLC backplane is properly seated.
