1734-TB | Allen-Bradley POINT I/O Terminal Base. It has 8 Positions and a Clamp Type of Cage-Clamp RTB

The 1734-TB is a Terminal Base from the POINT I/O series by Allen-Bradley. It acts as the mounting and connection base for POINT I/O modules and provides power, communication, and grounding connections. The 1734-TB is typically used in ControlLogix, CompactLogix, or Flex I/O systems to connect I/O modules to the system backplane and establish communication with the controller.

The manual for the 1734-TB can be found on the Rockwell Automation website. To access the manual:

1. Visit the Rockwell Automation or Allen-Bradley support site.
2. Search for 1734-TB in the product documentation section.
3. Download the user manual, which provides detailed information on installation, wiring, and system integration.

Alternatively, you can access the user manual within Studio 5000 or RSLogix 5000 if you are using these software packages for PLC programming.

The 1734-TB serves as the mounting base for POINT I/O modules, providing the necessary physical and electrical connections between the modules and the I/O system backplane. It supplies:

• Power connections for the I/O modules.
• Data communication between the modules and the controller via the backplane.
• Grounding to ensure system stability and safety.

Without the 1734-TB, the POINT I/O modules cannot be properly powered or communicate with the system’s controller.

The 1734-TB Terminal Base has several connections for power, communication, and grounding. The basic wiring configuration includes:

1. Power Connections:

• The 1734-TB requires a 24V DC power supply to power the POINT I/O modules. Power is supplied to the 24V DC and 0V (ground) terminals on the terminal base.
• Ensure that the power supply is correctly wired to the 24V and 0V terminals to provide power to the modules mounted on the base.

2. Communication Connections:

• The terminal base also facilitates communication between the I/O modules and the PLC system. This connection is typically made via Ethernet/IP or other communication backplane protocols, depending on the system setup.

3. Grounding:

• The 1734-TB terminal base includes a ground terminal. Proper grounding is essential to ensure system stability and reduce electrical noise interference.

Always refer to the wiring diagram in the user manual for specific terminal locations and configuration details.

The 1734-TB requires a 24V DC power supply to power the POINT I/O modules mounted on it. The power supply must meet the following requirements:

• Voltage: 24V DC (±10%).
• The power supply must be capable of providing sufficient current for all connected I/O modules. The current consumption of each module varies depending on the module type, such as digital or analog inputs/outputs.

Check the module specifications in the user manual for detailed power consumption information.
