Introduction
As industrial automation evolved from simple relay logic to sophisticated distributed control, the need for precise and flexible analog signal acquisition became paramount. The Schneider Electric TSXAEY800 analog input module addresses this demand, offering a reliable interface for monitoring process variables in manufacturing, water treatment, and energy management systems. Designed for the TSX Micro PLCs series, this module brings high-level input capability to legacy and modern control architectures alike.
Technical Specifications Breakdown
The TSXAEY800 provides eight high-level analog inputs, each configurable for current (0-20 mA, 4-20 mA) or voltage (+/-10 V, 0-10 V, 0-5 V, 1-5 V) signals. Its 12-bit analog-to-digital conversion ensures adequate resolution for most industrial sensors. Measurement error ranges from 0.15% to 0.41% of full scale, depending on input type and operating temperature (0 to 60 °C). The module offers two read cycle modes: a fast cycle of 3 ms plus 3 ms per channel used, and a nominal cycle of 27 ms. Electrical isolation of 1000 Vrms between channels and bus, and between channels and ground, protects against ground loops and interference. Input overvoltage protection spans -15 to +15 V at state 0 and -30 to +30 V at state 1, safeguarding the module from transient spikes. The unit consumes 270 mA at 5 V DC and connects via a single SUB-D 25 connector. Its IP20 degree of protection makes it suitable for clean indoor environments.
Industry Applications
In water and wastewater treatment plants, the TSXAEY800 monitors flow meters and pressure transmitters using 4-20 mA current loops, ensuring accurate dosing and pump control. For packaging machinery, voltage inputs (0-10 V) from position sensors enable precise registration control. The module's fast read cycle time supports applications requiring quick response, such as web tension monitoring in printing presses. By integrating with TSX Micro PLCs, it provides a cost-effective upgrade path for facilities modernizing their control systems without replacing the entire platform.
Installation & Setup Guidance
Mount the TSXAEY800 on a standard DIN rail within an IP20-rated enclosure. Connect analog sensors to the SUB-D 25 connector using shielded twisted-pair cables to minimize noise. Ensure the module's power supply delivers 5 V DC at 270 mA. Configure input types via the PLC programming software, selecting the appropriate range for each channel. Verify wiring polarity for current inputs and voltage inputs. After installation, perform a calibration check using a known reference signal to confirm measurement accuracy within the specified error limits.
Maintenance & Reliability
Periodically inspect the module for dust accumulation and ensure the enclosure maintains IP20 protection. Check all cable connections for tightness and signs of corrosion. The TSXAEY800's solid-state design requires no routine calibration, but verifying measurement error annually against a standard helps maintain process integrity. Store spare modules in a clean, dry environment between -25 and 70 °C. Following these practices extends service life and reduces unplanned downtime, contributing to a lower total cost of ownership.
Compatibility & Integration
The TSXAEY800 is designed exclusively for the Schneider Electric TSX Micro PLCs platform. It integrates seamlessly with the Modicon Premium automation platform as part of the product range. No additional communication protocols are required for basic operation; the module communicates via the backplane bus. For system expansion, pair it with other TSX Micro I/O modules. Always verify firmware compatibility with your PLC CPU before installation.
Selection Guide & Purchasing Advice
Before ordering, confirm that your PLC system is a TSX Micro series and that the rack has an available slot. The TSXAEY800 is a standard-format module.

Frequently Asked Questions
Q1: Can the TSXAEY800 accept both current and voltage signals simultaneously?
Yes, each of the eight channels can be independently configured for current (0-20 mA or 4-20 mA) or voltage (+/-10 V, 0-10 V, 0-5 V, 1-5 V) inputs, allowing mixed-signal applications.
Q2: What is the maximum cable length for analog inputs?
While the datasheet does not specify a maximum cable length, use shielded twisted-pair cables and keep runs under 100 meters to minimize noise and voltage drop.
Q3: Does the module provide isolation between individual channels?
No. The TSXAEY800 has a common point for all channels; isolation is provided between channels and bus (1000 Vrms) and between channels and ground (1000 Vrms), but not between individual channels.
Q4: How do I interpret the fast read cycle time?
The fast cycle time is 3 ms plus an additional 3 ms per channel used. For example, using all eight channels yields 3 + (8 x 3) = 27 ms, matching the nominal read cycle time.
Q5: Is the TSXAEY800 CE marked?
Yes, the module carries CE marking, indicating compliance with European health, safety, and environmental standards.
