Product Overview
When you need precise temperature or voltage measurements in your automation system, the Schneider TSXAEY1614 analog input module delivers reliable performance. Part of the TSX Micro PLC series, this module offers 16 high-level input channels with 16-bit analog-to-digital conversion. It 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 versatility reduces the need for multiple modules, lowering your overall system cost.
Technical Specifications Breakdown
Input Channels and Resolution
The TSXAEY1614 provides 16 analog input channels, each with a 16-bit conversion resolution. This high resolution ensures accurate readings, which minimizes measurement errors and reduces waste in processes like temperature control. For example, the measurement error for thermocouple E at 25°C is only 0.8°C, helping you maintain product quality and avoid costly rework.
Read Cycle Time
With a nominal read cycle time of 70 ms per channel, the module delivers timely data for control loops. Faster cycle times can improve system responsiveness, potentially reducing energy consumption by optimizing heating or cooling cycles.
Isolation and Protection
The module features 1000 Vrms isolation between channels and the bus, as well as between channels and ground. This robust isolation protects against ground loops and electrical noise, reducing downtime and maintenance costs. Common mode voltage handling of 250 V AC or 280 V AC between channels and 250 V DC between channels and earth further enhances reliability in harsh industrial environments.
Power Consumption
The TSXAEY1614 consumes only 300 mA at 5 V DC, keeping your power supply costs low and reducing heat generation inside the control cabinet.
Industry Applications
Temperature Monitoring in Chemical Processing
In chemical plants, precise temperature control is critical for reaction efficiency and safety. The TSXAEY1614 connects directly to thermocouples (types J, K, or T) to monitor reactor temperatures. Its 16-bit resolution and low measurement error help maintain optimal conditions, reducing energy usage and improving yield.
Furnace Control in Metalworking
For heat treatment furnaces, the module supports thermocouple types R, S, and B, which are common for high-temperature measurements. The 70 ms read cycle time allows for quick adjustments to burner controls, saving fuel and extending equipment life.
Installation & Setup Guidance
Mount the TSXAEY1614 in a standard format slot of your TSX Micro PLC rack. Use two SUB-D 25 connectors for electrical connections, ensuring secure wiring to minimize signal noise. Verify that the input overvoltage protection range (-15 to 15 V at state 0, -30 to 30 V at state 1) matches your sensor outputs. Operate the module within 0 to 60°C ambient temperature and 10 to 95% relative humidity without condensation to maintain accuracy and longevity.
Maintenance & Reliability
Regularly inspect the SUB-D 25 connectors for corrosion or loose wires, as poor connections can introduce measurement errors. Keep the module clean and within its operating temperature range to prevent drift. The IP20 degree of protection means it is suitable for clean, dry indoor environments. Following these simple steps reduces unplanned downtime and extends the module's service life, improving your return on investment.
Compatibility & Integration
The TSXAEY1614 integrates seamlessly with the Modicon Premium Automation platform and TSX Micro PLCs. It complies with standards including NFC 42-330, IEC 1131, DIN 43710, IEC 751, DIN 43760, and IEC 584. Certifications from DNV, RMRS, LR, ABS, RINA, BV, and GL ensure suitability for marine and industrial applications. Before ordering, verify that your PLC base supports this module.
Selection Guide & Purchasing Advice
When selecting the TSXAEY1614, confirm that your application requires 16 analog inputs and thermocouple or voltage measurement. Check the module format (standard) and ensure your cabinet has adequate space. At SpareTechPLC, we stock this module and can help you verify compatibility with your existing system.

Troubleshooting & Common Issues
If you encounter inaccurate readings, first check the thermocouple wiring and connector integrity. Ensure the common mode voltage does not exceed 250 V AC or 280 V AC between channels. For no communication, verify that the module is properly seated in the rack and that the 5 V DC power supply delivers at least 300 mA. If problems persist, consult the Schneider documentation for detailed diagnostics.
