Product Description

The B&R X20TB12 is a 12-pin terminal block for the B&R X20 automation system. It’s a crucial accessory for connecting I/O signals and power to various X20 modules, including the X20PS9400 power supply. The terminal block features push-in technology, which allows for quick, tool-free wiring. Wires are inserted by simply pushing them into the terminal point, and can be released with a small lever. The block is also designed to be “keyed” to prevent incorrect installation on modules with different voltage requirements, ensuring safety and proper function.

Product Parameters

Product Advantages

• Fast and Easy Wiring: The push-in technology allows for quick, tool-free wiring, which significantly reduces installation time and effort. A lever is used for simple wire release.
• High Reliability: The push-in mechanism provides a secure and vibration-resistant connection, ensuring reliable signal and power transmission in harsh industrial environments.
• Clear Identification: Each terminal point is uniquely numbered and can be labeled with plain text, which helps prevent wiring errors and simplifies maintenance and troubleshooting.
• Safe and Secure: The terminal block is “keyed” for 24 VDC to prevent it from being incorrectly plugged into modules with different power requirements, minimizing the risk of damage.

Precautions

• Proper Wire Stripping: For a secure connection, wires must be stripped to a length of 7 to 9 mm. Incorrect stripping can lead to a poor contact.
• Use Only Copper Wires: The terminal block is designed to be used exclusively with copper wires. Using aluminum wires is not permitted.
• Wiring with End Sleeves: If using fine-stranded wires, B&R recommends using wire end sleeves with square crimping to achieve optimal cable retention force.
• Voltage Limits: Always consider the specific voltage and current limits of the connected X20 I/O module. The terminal block’s ratings are the maximum limits, and the module’s ratings may be lower.
• No High Tension: Ensure the cables are not under excessive tension, as this can exceed the cable holding force and cause a connection to come loose, resulting in a malfunction.

Product Applications

The B&R X20TB12 is an essential part of the B&R X20 system, used wherever a reliable electrical connection is needed. Its applications include:

• I/O Module Connection: It serves as the primary interface for wiring digital and analog I/O signals for various X20 I/O modules.
• Power Supply: It’s used to provide the 24 VDC power supply to the X20PS9400 power supply module, as well as the power for the bus controller and the X2X Link.
• Industrial Automation Systems: Used widely in industrial control panels, distributed I/O boxes, and on-machine control systems that rely on the B&R X20 platform.
• Machine and Plant Engineering: It simplifies wiring in custom machinery and plant infrastructure, where quick and reliable connections are crucial for commissioning and maintenance.
