FAQ
FAQ
Q1. What is the main function of 1794-TB3G?
It is a terminal base used to connect field wiring to FLEX I/O modules while providing a grounded connection and FlexBus backplane interface.
Q2. What does the “G” mean in TB3G?
“G” stands for Grounded, meaning the base includes dedicated grounding terminals for improved noise protection and system safety.
Q3. What modules is it used with?
It is compatible with most FLEX I/O modules including digital, analog, and specialty modules that require TB3-type bases.
Q4. How is it different from TB3 / TB3S?
- TB3: standard screw clamp
- TB3S: spring clamp
- TB3G: screw clamp + enhanced grounding design
Q5. What is FlexBus?
FlexBus is the internal backplane that carries communication and power between the terminal base and the I/O module.
Q6. What is its voltage rating?
It supports up to approximately 31.2 VDC/AC field wiring systems.
Q7. Can modules be replaced while powered?
Yes, FLEX I/O supports RIUP (Removal and Insertion Under Power) depending on configuration.
Q8. Why is grounding important in TB3G?
It helps reduce electrical noise, improves signal stability, and increases safety in industrial environments.
