PLCs, Power Supplies & Others

The Schneider TSX4740 delivers a powerful, all-in-one control solution within the Telemecanique TSX series. This integrated CPU module combines a programmable logic processor with two built-in digital inputs and a high-current relay output. Consequently, it provides an efficient and compact foundation for a wide range of standalone machine automation tasks, eliminating the need for separate input and output modules in simple systems.

Integrated I/O Capabilities and Electrical Ratings

This unit features two dedicated 24VDC digital inputs for connecting push buttons, limit switches, or sensor signals directly. Its standout feature is a robust integrated relay output contact rated to handle substantial loads up to 100 Amperes, making it suitable for directly controlling motors, solenoids, or contactor coils. Moreover, a clear LED indicator provides immediate visual confirmation of power status and operational mode for quick diagnostics.

Programming, Memory, and Communication

The TSX4740 is programmed using dedicated Schneider Electric software, such as PL7, to execute custom ladder logic or instruction list programs. It contains onboard user memory for storing the control program, variables, and data, facilitating complex sequencing, timing, and counting functions. This module can also serve as a central control point in small networks or communicate with human-machine interfaces (HMIs) for basic operator interaction.

Physical Design and Installation

Designed for DIN rail mounting, this CPU module integrates seamlessly into standard industrial control panels. Its self-contained design minimizes the required panel space and wiring complexity for compact machines. The robust housing protects the internal electronics from typical panel environment contaminants like dust and electrical noise.

Typical Applications and System Role

The TSX4740 excels in applications requiring a simple, cost-effective, and reliable control unit. Common uses include controlling small conveyors, packaging machines, industrial fans, pumps, and material sorting systems. It serves as the primary logic brain for these machines, processing input signals and activating the high-power output to drive the final load based on the programmed sequence.
