General
Input voltage	< 25 VDC

The Moxa TB-M25 is a wiring kit for industrial applications, specifically developed for use with serial interfaces and communication devices from Moxa. It features a DB25 (male) connector mounted on a DIN-rail terminal base. This design enables quick and secure integration into existing control and automation systems, particularly in environments where a fixed, mechanically robust connection is required. The device is designed for use in industrial installations, test environments, or control systems where reliable serial data transmission over standardized interfaces is necessary.

Applications

The TB-M25 is designed for industrial environments with high requirements for mechanical stability and temperature resistance. It is particularly suitable for applications in manufacturing automation, process control, or building automation, where serial connections via DB25 interfaces are required. The high temperature tolerance also makes it suitable for locations exposed to extreme heat, such as near machines with high heat output.

Features and Equipment in Detail

The kit provides a DB25 (male) connector directly mounted on a DIN rail. This allows for simple and standardized installation in enclosures or control cabinets. The connection is made via a DIN-rail terminal construction, ensuring a secure and mechanically stable connection. Wiring is done using screw terminals designed for cable cross-sections of 24 to 12 AWG. This covers a wide range of industrial cable types, from fine control wires to robust connection cables.

Technology Explained Simply

The DB25 (male) connector is a standard in industrial communication technology, especially for serial interfaces such as RS-232 or RS-485. The use of a DIN-rail terminal base enables quick mounting and maintenance, as the device is directly clipped onto a standard DIN rail. The screw terminals ensure a firm mechanical connection that remains stable even under vibration or mechanical stress. The maximum operating temperature of 105 °C makes the device suitable for high-temperature environments, while the minimum of -40 °C allows use in cold environments, such as in refrigeration systems or outdoor applications.

Compatibility and Accessories

The TB-M25 is specifically developed for use with Moxa communication devices but can also be used with other devices supporting a DB25 interface. It is part of a comprehensive product family of Moxa Wiring Kits, which also includes models with DB9 connectors, RJ45-to-DB9 adapters, and screw terminal adapters. These products can be combined as needed to create flexible wiring solutions for various industrial scenarios. Compatibility with various cable cross-sections (24 to 12 AWG) increases flexibility in selecting connection cables.

Mounting and Installation

Installation is done by direct mounting onto a DIN rail, typically found in enclosures or control cabinets. The screw terminals allow for easy and secure connection of wires. Installation requires no special tools, except a screwdriver for securing the cables. DIN rail mounting enables quick installation and maintenance, as the device can be easily removed and reinstalled.

Operational Advantages

The TB-M25 offers a mechanically robust and reliable connection that remains stable even under industrial conditions with vibrations, temperature fluctuations, and mechanical stress. The high temperature resistance from -40 to 105 °C significantly expands the range of applications. The use of screw terminals for cable cross-sections of 24 to 12 AWG ensures flexible adaptation to various cable types. DIN rail mounting enables standardized and quick integration into existing systems.

Input Voltage and Electrical Properties

The electrical specification is limited to serial data transmission with an input voltage of less than 25 VDC. This is typical for serial interfaces and ensures the device is used only for data transmission and not for powering devices. The voltage is therefore not intended for powering external devices, but is exclusively for signal transmission.

Environmental Conditions

The device is designed for operating temperatures of -40 to 105 °C, making it suitable for a wide range of industrial environments, including high-temperature applications. The specific temperature range applies to models TB-M9, TB-F9, TB-M25, and TB-F25, highlighting the high robustness of this product series. Operating temperature is thus a key factor in selecting the appropriate wiring kit for demanding environments.

Scope of Delivery

The scope of delivery includes 1x wiring kit (model-dependent). This is the TB-M25 model, i.e., a DB25 (male) on DIN-rail terminal.
