Description
The TSXAEY800 is a high-precision, 8-channel analog input module from Schneider Electric, designed for the Modicon TSX Premium and TSX Quantum PLC platforms. It enables accurate acquisition of voltage or current signals from field sensors—such as pressure transmitters, temperature RTDs (via external transmitters), flow meters, and level probes—in industrial automation systems.
With 16-bit resolution, galvanic isolation, and flexible signal configuration per channel, the TSXAEY800 delivers reliable process data for applications demanding tight control, such as water treatment, HVAC, food & beverage, and energy management.
Application Scenarios
At a municipal water purification plant in France, operators needed to monitor eight critical parameters—including raw water pH, chlorine residual, and filter differential pressure—using 4–20 mA transmitters. The TSXAEY800 was installed in a Modicon TSX Premium rack to digitize these signals with 0.1% accuracy. During a chemical dosing upset, the module’s high-resolution data allowed the PLC to detect a 0.3 mA drift in the pH transmitter—triggering an early calibration alert before water quality was compromised. Over five years of continuous operation, the TSXAEY800 maintained stable performance despite electrical noise from nearby pump VFDs, thanks to its robust channel-to-channel isolation. For facilities where measurement integrity equals regulatory compliance, the TSXAEY800 turns analog signals into trusted digital intelligence.

Technical Principles and Innovative Values
Innovation Point 1: Per-Channel Signal Flexibility
Each of the 8 channels can be independently configured for voltage or current—no DIP switches or jumpers required. Configuration is done entirely in software (e.g., Unity Pro), enabling rapid re-deployment across different processes.
Innovation Point 2: True Differential Inputs with High CMRR
The TSXAEY800 uses differential amplifiers on all channels, rejecting common-mode noise (e.g., ground loops) up to 120 dB—critical in electrically noisy plants with motors, welders, or VFDs.
Innovation Point 3: 16-Bit Precision for Tight Control Loops
With 65.536 discrete steps across the range, the module supports fine-grained control—enabling smoother PID responses in applications like boiler drum level or fermentation temperature.
Innovation Point 4: Seamless Integration with Unity Pro
Auto-detection in Unity Pro XL simplifies configuration: engineers assign engineering units (e.g., °C, bar, %), and the software handles scaling, filtering, and alarm thresholds natively.
Application Cases and Industry Value
In a dairy processing line in the Netherlands, pasteurization temperature must stay within ±0.5°C to meet EU hygiene standards. The TSXAEY800 reads four PT100-to-4-20mA converters with 0.05°C resolution, feeding data to a TSX Premium PLC that modulates steam valves in real time. Since installation, batch rejection due to temperature excursions dropped by 92%. Similarly, a district cooling plant in Dubai uses TSXAEY800 modules to monitor chiller evaporator/condenser pressures across 12 circuits—enabling predictive maintenance based on subtle trend deviations, reducing energy consumption by 8% annually.
