Schneider TSXH5724M TSX Micro PLC: Reliable Automation Controller

Product Overview

This micro PLC supports up to 1024 discrete I/O and 80 analog I/O, making it suitable for a wide range of automation tasks. Its single rack configuration accepts 6, 8, or 12 slots, allowing flexible expansion without unnecessary complexity.

Technical Specifications Breakdown

The TSXH5724M provides robust processing capabilities. Key specifications include:

• Discrete I/O Processor Capacity: 1024 I/O
• Analog I/O Processor Capacity: 80 I/O
• Application-Specific Channels: ≤ 24
• Process Control Channels: ≤ 10 (up to 30 simple loops)
• Integrated Connections: Ethernet TCP/IP RJ45, USB type A (12 Mbit/s), and a serial link (female mini DIN RS485, 19.2 kbit/s)
• Memory: Internal RAM with PCMCIA card: 768 kB program, 192 kB data; without PCMCIA card: 192 kB program and data. PCMCIA card provides 16384 kB additional data storage.
• Execution Time: 0.039–0.057 µs Boolean (without PCMCIA card), 0.048–0.057 µs Boolean (with PCMCIA card), 0.054–0.073 µs word or fixed-point arithmetic, 0.055–0.063 µs floating points.
• Instruction Throughput: 11.4 Kinst/ms (65% Boolean + 35% fixed arithmetic) or 15.75 Kinst/ms (100% Boolean).
• System Overhead: 1 ms master task.

These specs translate to fast, deterministic control for discrete manufacturing and process applications. The dual memory configuration ensures you can scale program complexity as needed.

Industry Applications

Typical applications include:

• Packaging Lines: Manage multiple sensors and actuators with the 1024 discrete I/O capacity. The Ethernet TCP/IP port enables quick integration with plant SCADA systems for real-time monitoring.
• Material Handling: Use the RS485 serial link to connect variable frequency drives or remote I/O racks over long distances. The 19.2 kbit/s rate ensures reliable data exchange.
• Process Control: With up to 10 process control channels handling 30 simple loops, this PLC can regulate temperature, pressure, or flow in smaller batch processes.

Installation & Setup Guidance

For maintenance engineers, straightforward installation reduces downtime. The TSXH5724M mounts in a single rack with 6, 8, or 12 slots. Follow these tips:

• Rack Selection: Choose the slot count that matches your I/O and communication module requirements. Leave spare slots for future expansion.
• Power Supply: The module draws 1880 mA at 5 V DC. Ensure your power supply can handle this load plus connected modules.
• Wiring: Use shielded twisted-pair cable for the RS485 serial link to minimize noise. For Ethernet, standard Cat5e or better cable is sufficient.
• Configuration: Program using Unity Pro software. The USB port (type A, 12 Mbit/s) provides a convenient local programming interface without needing a dedicated network.

Maintenance & Reliability

Reliability is paramount. The TSXH5724M operates in ambient temperatures from 32 to 140 °F (0 to 60 °C) and storage temperatures from -13 to 158 °F (-25 to 70 °C). Its IP20 protection and pollution degree 2 rating make it suitable for clean industrial environments. To maximize service life:

• Inspect Annually: Check for dust accumulation on the enclosure and ensure ventilation slots are clear.
• Monitor LEDs: The front panel LEDs indicate processor run, Ethernet status, and I/O faults. Use these for quick diagnostics.
• Backup Programs: Regularly save the program and data to the PCMCIA card (16384 kB storage) for quick recovery after a failure.

Compatibility & Integration

It supports:

• Ethernet TCP/IP: 10BASE-T/100BASE-TX for plant network connectivity.
• USB: Type A port at 12 Mbit/s for local programming.
• RS485 Serial Link: Female mini DIN connector at 19.2 kbit/s for legacy devices or remote I/O.
• CPU Sync Link: Exchanges up to 192 kB of data between processors.

This flexibility allows you to retrofit into existing Schneider systems or build new distributed architectures.

Selection Guide & Purchasing Advice

Before ordering the TSXH5724M, verify your system requirements:

• Rack Size: Confirm you have a compatible rack with the needed slot count (6, 8, or 12).
• Memory Needs: If your program exceeds 192 kB, order a PCMCIA card separately.
• Lifecycle Status: Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

From a maintenance viewpoint, common issues include:

• Ethernet Link Failure: Check the RJ45 cable and ensure the port LED (green RUN) is lit. If the red ERR LED is on, verify IP address settings.
• RS485 Communication Errors: Ensure termination resistors are installed at both ends of the serial link. Verify baud rate matches the connected device (19.2 kbit/s).
• Memory Overflow: If the program fails to download, the internal RAM may be full. Use a PCMCIA card to expand program memory to 768 kB.
