FAQ
FAQ
Q1. What is the main function of 1794-TB32?
It is a 32-point terminal base used to connect field wiring to FLEX I/O modules and provide backplane communication.
Q2. Does it process signals or control logic?
No, it is only a wiring and connection interface. All processing is done by the attached I/O module.
Q3. What makes TB32 different from TB2 or TB3?
- TB2 / TB3: used for 8–16 point modules
- TB32: designed specifically for high-density 32-point modules
Q4. What modules use TB32?
Commonly used with 32-point modules like 1794-IB32, 1794-OB32, and similar high-density FLEX I/O modules.
Q5. How does it connect to the system?
It snaps onto the DIN rail and connects via FlexBus backplane to the I/O adapter.
Q6. Can modules be replaced while powered?
Yes, FLEX I/O supports RIUP (Removal and Insertion Under Power) depending on system configuration.
Q7. What is the voltage rating?
Up to approximately 31.2 VDC/AC systems, depending on installation design.
Q8. What is its role in the system architecture?
It serves as the high-density wiring base that distributes field signals to FLEX I/O modules efficiently while maintaining modular replacement capability.
