Product Overview

The Schneider Telemecanique TSX1712028 is a compact, self-contained programmable logic controller (PLC) designed for the TSX 17 series platform. This unit integrates processing capabilities with fixed onboard I/O, providing a robust solution for localized automation tasks in industrial environments including power plant cooling systems, mining conveyor controls, and automated pumping stations. By utilizing an all-in-one architecture, the TSX1712028 reduces the need for complex external bus cabling, thereby increasing system reliability and simplifying maintenance in critical control loops.

Features

• Integrated 20-point I/O configuration: 12 discrete inputs and 8 electromechanical relay outputs.
• High-speed logic execution: 3.5 microseconds per Boolean instruction for responsive real-time control.
• Integrated power supply: Operates directly from 100-240 V AC line power.
• Rugged relay outputs: Supports direct switching of AC or DC loads without the need for interposing relays.
• Optical isolation: Discrete inputs are internally isolated to protect the internal data bus from field-side voltage transients.
• Real-time diagnostics: Front-panel LED indicators provide immediate status monitoring for inputs, outputs, and system health.
• Non-volatile memory: Internal storage ensures instruction set retention during power interruptions.

Applications

This controller is suited for standalone machine control or as a distributed controller within larger legacy Modicon/Telemecanique automation architectures. Its compact design makes it ideal for space-constrained control panels in industrial infrastructure, small-scale process automation, and auxiliary equipment monitoring.

Technical Specifications

Installation Guidelines

• Ensure the controller is mounted in a well-ventilated enclosure to maintain ambient temperatures within the 0-55 deg C range.
• Always disconnect main power before performing any wiring, module insertion, or removal.
• Use shielded cables for communication and high-speed input lines to minimize electromagnetic interference (EMI).
• Verify that input voltage polarity matches the specific sink/source configuration of the input block.
• Ground the chassis properly to a common industrial earth point to ensure noise immunity and safety.
• Keep high-voltage power lines and low-voltage signal lines in separate cable trays to prevent inductive coupling.

FAQ

Is the TSX1712028 compatible with modern programming software?
The TSX 17 series is a legacy platform. Programming typically requires specific legacy Telemecanique software and the appropriate serial communication hardware interface.

Does this unit require an external power supply for the inputs?
Yes, the 24 V DC discrete inputs require an external power source to function, ensuring electrical isolation from the AC supply.
