Schneider TSXAEY1614 Overview
The Schneider TSXAEY1614 is a 16-channel analog input module designed for the TSX Micro PLC series. It supports thermocouple types B, E, J, K, L, N, R, S, T, and U, plus voltage inputs in the ±80 mV range. With 16-bit analog-to-digital conversion, this module delivers high-resolution measurements for precise temperature and voltage monitoring in industrial processes.
Its nominal read cycle time of 70 ms per channel ensures timely data acquisition, making it suitable for real-time control applications. The module provides robust isolation of 1000 Vrms between channels and bus, and between channels and ground, which enhances signal integrity and protects against electrical noise.

Key Technical Specifications
The TSXAEY1614 operates on a 5 V DC supply and consumes 300 mA. It features two SUB-D 25 connectors for straightforward wiring. The module offers input overvoltage protection from -15 to 15 V at state 0 and -30 to 30 V at state 1, safeguarding the inputs from transient surges.
Measurement error varies by thermocouple type; for example, thermocouple E has an error of 0.8°C at 25°C, while thermocouple B shows 2.5°C at the same temperature. These accuracy levels support reliable temperature sensing across different sensor types.

Isolation and Common Mode Rejection
With 1000 Vrms isolation between channels and bus, and between channels and ground, the module minimizes interference and ensures stable readings. It handles common mode voltages up to 250 V AC or 280 V AC between channels, and 250 V DC between channels and earth, which is critical in industrial environments with high electrical noise.
Environmental Ratings and Certifications
The TSXAEY1614 operates in temperatures from 0 to 60°C and stores from -25 to 70°C. It withstands relative humidity from 10 to 95% without condensation. The module carries CE marking and certifications from DNV, RMRS, LR, ABS, RINA, BV, and GL, making it suitable for marine and industrial applications. Its IP20 protection and pollution degree 2 rating ensure dependable performance in typical control cabinets.
Integration and Applications
Engineers can integrate the TSXAEY1614 into TSX Micro PLC systems to monitor multiple thermocouples or low-level voltage signals. Its high channel count reduces the need for multiple modules, saving space and cost. The 16-bit resolution allows fine temperature distinctions, which is essential in processes like heat treatment or chemical reaction monitoring.
For best results, follow wiring guidelines for SUB-D connectors and ensure proper grounding to leverage the module's isolation features. Regular calibration checks can maintain measurement accuracy over time, especially when using different thermocouple types.
The Schneider TSXAEY1614 combines high input density, robust isolation, and broad thermocouple support, making it a versatile choice for precise analog measurement in industrial automation.
