I/O Density Scaling & Firmware Flash Compatibility

The TU 715F terminal unit enables modular I/O density scaling by serving as the physical interface layer for S700 I/O modules on the DIN rail. Integrated internal bus traces connect field signals directly to the local backplane, facilitating low-latency transmission across deterministic networks. Replacing or swapping inserted active I/O cards on the base unit does not disturb existing field wiring, maintaining overall system firmware flash compatibility and uninterrupted backplane communication velocity across adjacent terminal slots.

Frequently Asked Questions

Q: What screw terminal wire gauge limits apply to the TU 715F terminal unit?

A: The screw connection blocks accommodate conductor cross-sections ranging from 0.08 mm2 up to 2.5 mm2 for 1-wire or 2-wire terminations.

Q: Can an active I/O module be replaced without disconnecting field wiring from the TU 715F?

A: Yes, field wiring attaches directly to the terminal unit, allowing the active S700 I/O module to be unclipped and replaced independently.

Field Installation Guidelines

  • Mount the terminal unit securely onto a standard 35 mm DIN rail prior to plugging in active S700 I/O modules.
  • Strip field wiring to the recommended length and torque screw terminals to standard specification to prevent loose mechanical contacts.
  • Connect shield wires to dedicated grounding buses to minimize high-frequency noise interference across signal channels.
  • Isolate external 24 VDC field supply voltages before attaching or removing terminal conductors.
