Schneider TSX3710028DR1 Modular Base Controller

The Schneider TSX3710028DR1 is a programmable logic controller (PLC) from the renowned Modicon TSX Micro series. This compact modular base controller is designed for applications where space is limited but reliability and performance cannot be compromised. The TSX3710028DR1 integrates 16 digital inputs and 12 relay outputs into a single base unit, eliminating the need for additional expansion modules in small systems.

Engineered by Schneider Electric, a global leader in automation and energy management, the TSX3710028DR1 supports 24V DC input and utilizes relay output channels, making it highly suitable for controlling electromechanical devices. This model supports UNI-TELWAY communication protocol, offering a stable and well-supported network connection for legacy industrial systems.

Though the product has reached end-of-life status and is no longer in active production, it remains widely used in legacy systems and can still be sourced from industrial parts suppliers for maintenance and refurbishment of existing installations.
