Schneider TSXAEY800 Analog Input Module for TSX Micro PLCs

Introduction

When an industrial process demands precise monitoring of multiple analog signals from sensors and transmitters, the Schneider Electric TSXAEY800 analog input module provides a reliable solution. This module, part of the TSX Micro PLCs series, handles up to eight high-level inputs, converting current or voltage signals into digital data for your control system. With its robust isolation and overvoltage protection, the TSXAEY800 ensures accurate readings even in electrically noisy environments.

Technical Specifications Breakdown

The TSXAEY800 offers eight high-level analog inputs, accepting current ranges of 0-20 mA and 4-20 mA, as well as voltage ranges of +/- 10 V, 0-10 V, 0-5 V, and 1-5 V. A 12-bit analog-to-digital converter provides resolution for these signals. The nominal read cycle time is 27 ms, while the fast read cycle time is 3 ms plus an additional 3 ms per channel used. Measurement error ranges from 0.15% to 0.41% of full scale, depending on input type and temperature. The module draws 270 mA at 5 V DC and provides 1000 Vrms isolation between channels and the bus, and between channels and ground. Input overvoltage protection is rated at -15 to +15 V for state 0 and -30 to +30 V for state 1.

Industry Applications

In manufacturing facilities, the TSXAEY800 monitors temperature, pressure, and flow signals from 4-20 mA transmitters, feeding data to a TSX Micro PLC for process control. For example, in a chemical blending system, the module reads level sensors and adjusts valve positions accordingly. Its fast read cycle time of 3 ms per channel supports applications requiring quick response, such as conveyor belt speed monitoring. The IP20 protection makes it suitable for clean indoor environments like control cabinets.

Installation & Setup Guidance

Mount the TSXAEY800 module onto a standard DIN rail within a TSX Micro PLC rack. Connect analog signals using the SUB-D 25 connector, ensuring proper wiring for current or voltage inputs. For current inputs, use a 250 Ohm resistor if needed. Verify that the 5 V DC supply can deliver at least 270 mA to the module. Configure input types and ranges via the PLC programming software, matching the sensor output. Avoid exposing the module to temperatures outside 0 to 60 °C or humidity above 95% without condensation.

Maintenance & Reliability

Periodically inspect the TSXAEY800 for dust accumulation on the IP20 enclosure and clean with a dry, low-pressure air stream. Check that all cable connections to the SUB-D 25 connector remain secure. The module's isolation of 1000 Vrms helps prevent ground loops, reducing signal drift over time. Routine calibration verification against a known reference can maintain measurement accuracy within the specified 0.15% to 0.41% error range. Operating within 0 to 60 °C and storing between -25 to 70 °C extends component life.

Compatibility & Integration

The TSXAEY800 integrates directly with Schneider Electric TSX Micro PLCs and is also compatible with the Modicon Premium automation platform. It supports CE marking and carries certifications from DNV, RINA, GL, BV, LR, RMRS, and ABS, making it suitable for marine and industrial applications. The module communicates over the PLC backplane, requiring no additional protocol configuration. For replacement or expansion, verify that your PLC rack has an available slot and adequate power budget for the 270 mA at 5 V DC consumption.

Selection Guide & Purchasing Advice

Before ordering the TSXAEY800, confirm that your TSX Micro PLC system supports this analog input module. Check the available slot count and power supply capacity. BluePLC Industrial stocks the TSXAEY800 and can advise on compatibility with your existing setup. For applications requiring more than eight inputs, consider multiple modules or a higher-density alternative. Always verify the current lifecycle status and availability with BluePLC Industrial before purchasing.
