Allen-Bradley 1734-TBS POINT I/O Terminal Base

The Allen-Bradley 1734-TBS, also cataloged as the 1734-TBS Terminal Base Unit, operates as a dedicated hardware component for field wiring termination within POINT I/O 1734 networks. It provides secure spring-clamp connections for up to 8 terminals, enabling reliable interfacing between field devices and I/O modules.

Hardware Specifications

I/O Density Scaling and Backplane Communication

The 1734-TBS terminal base supports modular I/O density scaling by providing a consistent electrical and mechanical interface between field wiring and POINT I/O modules. Its spring-clamp design maintains stable contact under vibration and shock conditions. The unit contributes to reliable backplane bus communication within the POINT I/O 1734 architecture, ensuring deterministic signal propagation and maintaining module alignment.

Frequently Asked Questions (FAQ)

Q: Can the 1734-TBS terminals accommodate both solid and stranded conductors?
A: Yes, the spring-clamp design supports standard field wiring, including both solid and stranded copper conductors within the rated cross-section.

Q: Is the 1734-TBS rated for harsh environmental conditions?
A: The terminal base operates between -20 to 55 deg C and can withstand non-condensing relative humidity from 5 to 95 %. It tolerates shock up to 30 G and vibration up to 5 G within 10-500 Hz.

Q: Does the terminal base require any maintenance after installation?
A: Routine inspection of spring-clamp terminals is recommended to ensure mechanical integrity, especially in high-vibration installations.

Field Installation Guidelines

• Mount the 1734-TBS on a properly secured DIN rail compatible with POINT I/O modules.

• Route wiring separately from high-current power lines to minimize electromagnetic interference.

• Use only copper conductors within the acceptable wire gauge for spring-clamp terminations.

• Tighten screw torque to the specified 0.6 Nm if applicable for auxiliary fasteners.

• Ensure environmental conditions fall within the specified operating temperature and humidity ranges.

• Avoid exposure to moisture or condensing environments unless the terminal is housed in a protective enclosure.

• Confirm all wiring connections are secure before energizing the network.

• Maintain clearance for vibration absorption and module removal without disturbing adjacent connections.
