General
Input voltage	< 25 VDC

The Moxa TB-M9 is a wiring kit for industrial applications, specifically designed for use with serial interfaces and communication devices from Moxa. It serves as a DIN rail terminal with a DB9 (male) connector, enabling simple and secure cabling in industrial environments such as control systems, test setups, or production lines. The construction is designed for robust and reliable installation, with connections made via screw terminals rated for cable cross-sections from 24 to 12 AWG. This range of cable sizes makes the device flexible for use, regardless of the cable thickness in the specific application area.

Applications

The TB-M9 is designed for industrial environments where a stable serial connection is required. It is particularly suitable for applications where devices communicate via serial interfaces, such as in automation technology, machine control, or process monitoring. The high temperature resistance of the device – it can operate in environments from -40 to 105 °C – also makes it suitable for demanding environments with high heat loads or extreme cold. Mounting is directly onto a DIN rail, enabling quick and standardized installation in enclosures.

Features and Equipment in Detail

The kit provides a DB9 (male) connector, which is directly connected to the screw terminals of the terminal. The terminals are designed to securely hold cables with a cross-section from 24 to 12 AWG, ensuring broad compatibility with various cable types. The connection is made via mechanical screw terminals, ensuring a firm and reliable electrical connection. The maximum operating voltage is under 25 VDC, which is intended exclusively for serial data transmission. This is not a power supply, but an interface for data communication.

Technology Explained Simply

The use of screw terminals instead of plug connections increases mechanical stability and reduces the risk of contact loss, especially in vibrating or moving environments. DIN rail mounting allows standardized fixation in enclosures and simplifies integration into existing systems. The temperature resistance from -40 to 105 °C ensures operation even in extreme environments, such as in manufacturing, outdoors, or in machine rooms with high heat generation. The maximum operating voltage of under 25 VDC is typical for serial interfaces and ensures that no hazardous voltages are present at the interface.

Compatibility and Accessories

The TB-M9 is part of a product family of Moxa Wiring Kits, which includes various connection types, such as DB9 (female), DB25 (male and female), and RJ45-to-DB9 adapters. It is specifically designed for use with Moxa devices, but can also be used in other systems requiring a DB9 interface. Compatibility with cables from 24 to 12 AWG allows use with a wide range of standard cables in industrial applications. Use in combination with other Moxa adapters, such as RJ45-to-DB9 adapters, expands application possibilities in networks integrating serial communication over Ethernet infrastructure.

Mounting and Installation

Mounting is done via a DIN rail, typically found in enclosures or control cabinets. The screw terminals are connected to the corresponding cables, with cable sizes ranging from 24 to 12 AWG. Mechanical fixation is achieved via screw terminals, which provide secure and durable holding. Installation requires no special tools, except a screwdriver for securing the cables. Positioning within the enclosure follows standard electrical installation guidelines.

Operational Advantages

The TB-M9 provides a robust and reliable connection for serial data transmission in industrial environments. The high temperature resistance and mechanical stability of the screw terminals ensure long service life and minimize maintenance requirements. DIN rail mounting enables quick integration into existing systems, and compatibility with a wide range of cable cross-sections increases installation flexibility. Use in combination with other Moxa products enables a consistent and standardized cabling solution in complex industrial networks.
