Backplane Bus Communication & I/O Density Scaling
The ABB TU515 terminal unit acts as the base wiring substrate for S500 analog and 24 VDC digital modules. Its integrated bus connectors pass backplane signal paths and supply power directly to the plugged I/O card without discrete internal wiring. This modular construction optimizes I/O density scaling across subrack DIN-rail layouts while ensuring hardware-level firmware flash compatibility between controller nodes and connected field sensors.
Frequently Asked Questions
Q: Can an S500 I/O module be swapped on the TU515 terminal unit without disconnecting field wiring?
A: Yes, the I/O module plugs directly onto the TU515 base, allowing card replacement while all screw-terminated field wiring remains permanently intact.
Q: What module types are supported by the TU515 base block?
A: The TU515 base supports S500 analog input/output modules and 24 VDC digital input/output modules.
Field Installation Guidelines
- Snap the TU515 terminal unit securely onto a standard 35 mm DIN rail prior to landing field conductors.
- Connect field signal wires to the designated screw terminals according to the system wiring diagram, verifying torque specs to prevent loose contacts.
- Ensure the primary 24 VDC power supply is isolated before seating or removing the operational I/O card onto the TU515 base connector.
- Maintain proper grounding by bonding the DIN rail to the main enclosure earth bus.
- Provide standard clearance around the IP20 housing to ensure proper natural convection cooling across the assembly.
