EtherNet/IP and Flex I/O Bus Interface Characteristics
The 1794-TB3T functions as a terminal base interface within the Allen Bradley Flex I/O architecture. The unit provides electrical termination between field devices and Flex I/O modules while maintaining FlexBus communication and power distribution requirements. The terminal base supports 3-wire temperature module connections and provides chassis grounding through dedicated terminals.
The FlexBus interface operates with a 5 VDC supply and 640 mA current capacity for connected I/O module communication. Proper installation requires correct terminal assignment, field wiring separation, and grounding continuity to maintain signal integrity across the I/O assembly.
Frequently Asked Questions (FAQ)
Q: Can the 1794-TB3T terminal base be hot-swapped during operation?
A: The terminal base is a passive connection component within the Flex I/O assembly. Hot-swapping procedures must follow the applicable Flex I/O system installation requirements and module replacement guidelines.
Q: What type of field wiring connection does the 1794-TB3T provide?
A: The unit uses cage clamp terminals for field wiring termination and includes dedicated chassis ground terminals for grounding connections.
Q: Is the 1794-TB3T compatible with temperature input modules?
A: The terminal base is designed for 3-wire temperature module applications within the Flex I/O 1794 product family.
Field Installation Guidelines
- Mount the terminal base on the Flex I/O assembly according to the system mechanical installation procedure.
- Verify terminal assignments before connecting field conductors.
- Maintain separation between signal wiring and high-voltage power conductors to reduce electrical interference.
- Connect chassis grounding terminals using appropriate industrial grounding practices.
- Confirm cage clamp terminal engagement and conductor retention before energizing the I/O system.
- Verify FlexBus alignment between adjacent Flex I/O components before module installation.
