General
Input voltage	< 25 VDC

The TB-F25 is a DB25 female connector wiring module from Moxa, specifically designed for mounting on a DIN rail in industrial automation environments. It serves as a wiring terminal for serial signals and enables a structured, reliable, and fast connection between DB25 interfaces and industrial control systems. The module is designed for use in harsh environments and supports cable cross-sections in the range of 24 to 12 AWG, ensuring broad compatibility with common industrial cables. The operating temperature ranges from -40 to 105 °C, making the device suitable for applications in extreme climatic conditions.

Applications
The TB-F25 is used in industrial control systems where serial interfaces must be connected via DB25 female connectors. Typical application scenarios include integrating legacy systems, connecting programming devices to controllers, or linking sensors and actuators via serial interfaces. The DIN rail mounting allows for a compact and standardized installation in enclosures, simplifying maintenance and system expansion.

Features and Equipment in Detail
The module features a DB25 female connector, serving as the physical interface. Wiring is done via terminals designed for cable cross-sections from 24 to 12 AWG. This cable size corresponds to a diameter of approximately 0.5 mm to 2.1 mm, which is sufficient for most industrial applications. The terminals allow for a secure and durable connection without requiring additional tools, reducing installation time.

Technology Explained Simply
The TB-F25 is powered by an input voltage of less than 25 VDC, required for serial data transmission. This voltage is typical for serial interfaces such as RS-232, RS-422, or RS-485, commonly used in industrial communication. The module itself is not an active power source but serves only as a mechanical and electrical transition point between cable and DB25 female connector. The operating temperature range of -40 to 105 °C indicates that the device functions reliably even in exceptionally cold or hot environments, such as production halls with high heat generation or outdoor areas in freezing conditions.

Compatibility and Accessories
The TB-F25 is compatible with all devices featuring a DB25 female connector and transmitting serial signals. It can be used in combination with industrial controllers, programming devices, or other equipment with a DB25 interface. Mounting is directly onto a DIN rail, enabling standardization within enclosures.

Mounting and Installation
Mounting is done by simply clipping the module onto a DIN rail, which is typically present in enclosures. Wiring is performed using the integrated terminals, designed for cable cross-sections from 24 to 12 AWG. Cables are inserted into the terminals and secured by pressure or a screw mechanism. No additional tools are required to fix the cables. Installation is therefore quick and can be carried out without specialized expertise.

Operational Advantages
The TB-F25 provides a stable and durable connection for serial signals, which in industrial environments are often subjected to high mechanical and thermal stresses. DIN rail mounting enables flexible and expandable installation, while the wide temperature resistance allows use in various climatic conditions. The support for cable cross-sections from 24 to 12 AWG ensures high flexibility in cable selection. Simple mounting and wiring reduce installation time and minimize the risk of incorrect connections.
