Processor Architecture and Integrated Design

The TSX3710128DTK1 integrates a 32-bit RISC processor running at 166 MHz. This processor executes boolean instructions in just 0.07 microseconds. The module provides 1 MB of flash memory for program storage. It includes 128 KB of RAM for runtime data and variables. The Schneider TSX3710128DTK1 supports up to 256 KB of user application code. A built-in power supply accepts 100-240 V AC directly from mains.

Built-in I/O and Expansion Capabilities

This modular base controller features 28 digital input channels on board. It also provides 16 transistor output channels for direct load control. The TSX3710128DTK1 expands to 512 digital I/O points using local racks. You can add up to 128 analog I/O channels for process applications. The controller connects to remote I/O via Ethernet or CANopen networks. A USB mini-B port allows direct PC connection for programming.

Communication Interfaces and Networking

The Schneider TSX3710128DTK1 includes a built-in Ethernet port with Modbus TCP/IP. This port supports HMI connection, programming, and plant network integration. The USB port serves as a high-speed programming interface. A CANopen option slot accepts a communication module for fieldbus networks. Seven status LEDs provide clear visual feedback about controller health. The green PWR LED indicates proper power supply operation.

Physical Dimensions and Installation Guidelines

The Schneider TSX3710128DTK1 weighs 0.975 kilograms for secure DIN rail mounting. Its height measures 103.6mm, width 171.2mm, and depth 116.4mm. Install this controller on standard 35 mm DIN rail inside the cabinet. The module consumes 35 VA of power from the AC supply. It operates reliably from 0°C to +60°C ambient temperature. Leave 50mm clearance above and below for proper air circulation.

Energy Storage and Battery Maintenance

The TSX3710128DTK1 uses a 240 mAh lithium battery for RAM backup. This battery preserves runtime data during power outages up to 30 days. The battery lasts approximately 10 years under normal conditions. Replace the battery when the red BAT LED indicator lights up. Always replace the battery with the Schneider TSX3710128DTK1 powered on. The module warns you one month before the battery reaches end of life.
