Product Introduction
The Schneider Electric STBDDO3600 is a Standard Digital Output Module designed for the Modicon STB (Smart Terminal Block) distributed I/O system. It provides discrete output control within distributed automation architectures and is widely used in industrial environments where space-saving, modular, and fieldbus-connected I/O systems are required.
The STBDDO3600 features 16 output channels, each capable of switching 24V DC signals. These outputs are sink-type (negative logic), meaning the module provides current to the load. It is compact, DIN-rail mountable, and designed for easy integration into Modbus, Profibus, EtherNet/IP, or CANopen-based distributed control systems via STB network adapters.
This module is ideal for controlling actuators, valves, indicators, solenoids, and other on/off devices in automated systems. With its rugged design, excellent diagnostics, and seamless integration, the STBDDO3600 plays a crucial role in improving system flexibility, reliability, and maintainability.
