Frequently Asked Questions (FAQ)

What communication protocol does this module use?

• The TU846 uses PROFIBUS DP-V1 protocol, which supports both cyclic data exchange and acyclic communication for parameterization and diagnostics.

What is the maximum wire size supported?

• This terminal unit accepts wire sizes from 0.25 mm² to 2.5 mm² (24-14 AWG), accommodating a wide range of industrial wiring standards.

Are there different temperature limits for mounting orientations?

• Yes, the TU846 has different maximum ambient temperature ratings: 55°C (131°F) for vertical mounting and 40°C (104°F) for horizontal mounting, due to differences in heat dissipation.
