Product Overview
When your automation system demands precise analog signal acquisition, the Schneider TSXAEZ802 delivers reliable performance. Part of the TSX Micro family, this analog input module converts current signals from field sensors into digital values for your PLC. With support for both 4-20 mA and 0-20 mA ranges, it handles a wide variety of industrial transmitters.
Technical Specifications
The TSXAEZ802 provides 8 input channels with 12-bit analog-to-digital conversion. Each channel accepts 4-20 mA or 0-20 mA current signals. The acquisition period is 32 ms, ensuring timely data updates for your control loop. Temperature drift is rated at 0.054 % per 10 °C, maintaining accuracy across changing ambient conditions. Input impedance is 250 Ohm, and isolation voltage reaches 1000 V AC. The module draws 60 mA from the backplane and weighs 0.2 kg.
Industry Applications
This module excels in process monitoring and control applications. For example, in a water treatment facility, the TSXAEZ802 reads 4-20 mA signals from pressure transmitters and flow meters. The 12-bit resolution provides fine granularity for precise level control. In a packaging line, it captures 0-20 mA signals from temperature sensors, enabling accurate heat sealing. The 32 ms acquisition period keeps up with moderate-speed processes.
Installation & Setup Guidance
Mount the TSXAEZ802 securely in your TSX Micro rack. Ensure proper backplane connection before powering the system. Wire each analog input according to the terminal markings, using shielded twisted-pair cable for noise immunity. Set the input range (4-20 mA or 0-20 mA) via the configuration software. Verify the 250 Ohm input impedance matches your transmitter specifications. After wiring, perform a loop test to confirm signal integrity.
Maintenance & Reliability
Periodically inspect the module for signs of dust or corrosion. Keep the enclosure clean and ensure adequate ventilation. The low temperature drift (0.054 % per 10 °C) reduces the need for frequent recalibration. Check the backplane current consumption (60 mA) to avoid overloading the power supply. Follow the manufacturer's guidelines for routine system checks.
Compatibility & Integration
The TSXAEZ802 integrates seamlessly with TSX Micro PLCs. It communicates over the backplane bus, requiring no additional configuration for data exchange. Use the standard TSX Micro programming software to assign input channels and scaling. The module is compatible with existing TSX Micro racks and power supplies.
Selection Guide & Purchasing Advice
Before ordering, verify your PLC rack has an available slot and sufficient backplane current capacity. The TSXAEZ802 draws 60 mA, so calculate total load. Confirm your sensors output 4-20 mA or 0-20 mA signals. For replacement or new installations, SpareTechPLC stocks this module for fast delivery. Contact our team to check availability and lead times.
