Schneider TSX3708056DR1 Modular Base Controller

The TSX3708056DR1 serves as a modular base controller for Schneider PLC systems. This unit provides the chassis backplane and processor for I/O modules. Its rectangular frame measures 270 millimeters in width. The controller height reaches 140 millimeters exactly. Depth stays at 115 millimeters. You will find this unit weighs approximately 2.1 kilograms. Therefore, installation requires four mounting screws on a flat panel. One backplane connector accepts up to eight expansion modules.

Physical Layout and Connectors

The front panel includes a 40-character LCD display for system status. You will find five navigation buttons for local configuration access. One RS-232 serial port connects to a programming laptop. A second RS-485 port supports Modbus communication networks. Removable terminal blocks provide power input and emergency stop connections.

Internal Design and Energy Storage

The TSX3708056DR1 contains approximately 1,240 discrete components inside. A 4700 microfarad capacitor bank smooths the main DC power bus. This bank holds enough charge for 30 milliseconds after power loss. The controller uses a 16-bit processor running at 24 megahertz. A lithium battery retains data memory for up to five years. EEPROM stores the user program without any battery backup.

Operational Performance

This modular base controller accommodates up to eight I/O modules simultaneously. It executes ladder logic from 64 kilobytes of program memory. Moreover, the unit includes 32 onboard digital inputs for immediate use. Twenty-four integrated transistor outputs switch DC loads directly. The LCD display shows real-time system status and fault messages. Five buttons let you navigate menus without a computer. Consequently, you achieve flexible control for medium-sized automation systems. Schneider designed this controller for Modicon Premium platform compatibility. Its metal chassis provides excellent electromagnetic shielding.

In summary, the TSX3708056DR1 delivers versatile base controller functionality. Use this unit for factory automation or process control applications. It simplifies system integration with built-in I/O points. Order this modular controller for your Schneider PLC system upgrade.
