It serves as the foundation for mounting and connecting Flex I/O modules to a system. This base unit helps simplify wiring and module installation. Its modular design makes it ideal for distributed control systems.

Question: How many terminals does the 1794-TB3G have?
Date Update:05/06/2025
Answer:

The 1794-TB3G terminal base features a total of 36 I/O terminals. These include 2 common terminals and 2 positive voltage terminals to support a variety of I/O configurations. It also includes 10 chassis ground terminals for proper grounding. This layout ensures flexibility in wiring and easy connection to external devices.

Question: Which technical features make the 1794-TB3G reliable in industrial applications?
Date Update:05/06/2025
Answer:
  • Operating Temperature: -20°C to 70°C ensures performance in hot and cold environments.
  • Storage Temperature: -40°C to 85°C allows safe transport and storage.
  • Shock Ratings: 30 g operating, 50 g non-operating for mechanical robustness.
  • Humidity Tolerance: 5-95% non-condensing for use in various humidity levels.
  • Vibration Rating: 5 g at 10-500 Hz supports stability in dynamic environments.
Question: How is the 1794-TB3G mounted?
Date Update:05/06/2025
Answer:

The 1794-TB3G can be mounted on a standard DIN rail or a panel. Its compact size of 94 x 94 x 69 mm allows it to fit into tight control cabinet spaces. This flexible mounting ensures easy integration into a wide range of system architectures. Proper mounting also ensures stable mechanical support and effective grounding.

Question: Can the 1794-TB3G support high-voltage signals?
Date Update:05/06/2025
Answer:

Yes, the 1794-TB3G can handle voltage/communication signals rated up to 125V DC/AC at 10A (50/60 Hz). However, for continuous voltage isolation, it is rated for a maximum of 50V DC using Basic Insulation. This insulation is tested for 60 seconds at 2121V DC between field wiring terminals and FLEXBUS or other modules. This design ensures electrical safety and reliable operation.
