Frequently Asked Questions (FAQ)

What is the difference between line and module redundancy?

  • Line redundancy protects against communication cable failures, while module redundancy provides backup if the I/O module itself fails. The TU848 supports both for maximum system reliability.

What voltage range does the power input support?

  • The TU848 accepts 24 V DC power with a wide input range of 19.2 to 30 volts, accommodating typical industrial voltage variations.

Can this module be replaced without shutting down the system?

  • No, the TU848 does not support hot swap functionality. System shutdown is required for module replacement or maintenance.
