Backplane Bus Communication Velocity & I/O Density Scaling
The TU710F terminal unit forms the structural and electrical backbone for sub-rack I/O expansion, sustaining backplane bus communication velocity across attached fieldbus communication modules. Its compact design optimizes cabinet I/O density scaling while spring-type terminals reduce connection impedance during high-vibration operation. Full firmware flash compatibility is maintained across swapped functional units without disrupting existing backplane routing paths.
Frequently Asked Questions
Q: How does the TU710F facilitate hot-swap replacement of attached functional modules?
A: The TU710F remains permanently wired to the DIN rail, allowing attached fieldbus or I/O modules to be unplugged without disconnecting field wiring or interrupting backplane bus continuity.
Q: What conductor termination technology is implemented on the TU710F?
A: The unit utilizes spring-type clamp terminals for field power and signal connections, providing constant tension against thermal expansion and vibration.
Q: Does the TU710F supply power directly to connected modules?
A: Yes. The terminal unit distributes 24 VDC field power and backplane signals directly to the plugged-in AC 700F module via rear connector buses.
Field Installation Guidelines
Perform the following technical steps during panel assembly and wiring:
- DIN-Rail Mounting: Hook the TU710F unit onto the top edge of the 35 mm DIN rail and press downward until the locking latch snaps into place.
- Spring Terminal Wiring: Insert a standard screwdriver into the spring release slot, push ferruled wires into the terminal opening, and release to secure clamp engagement.
- Sub-D Cable Termination: Align the 9-pin Sub-D fieldbus connector with the front port and tighten retaining screws to 0.4 N-m torque.
- Ground Bus Bonding: Connect the terminal unit grounding point to the cabinet copper ground bar using a short, low-impedance conductor strap.
