01
Product Identification
TU510 is the spring-terminal serial interface base for supported ABB AC500/S500 communication interface modules. It combines the plug-in module connection, serial-network connector, field signals and process-supply terminals in one DIN-rail assembly.
The base is the spring-clamp counterpart to TU509. Keeping those variants separate is important because their conductor-termination methods and order codes differ.

Functions
- Carries one supported communication interface module and secures it with two mechanical locks.
- Routes the module serial network to the integrated 9-pin D-sub connector.
- Provides field-signal and 24 V DC process-supply termination through spring clamps.
- Links the station to the I/O bus through the terminal-unit connector.
- Allows the plug-in module to be serviced while the field wiring stays on the base under the applicable procedure.
04
Applications
- AC500/S500 serial communication stations using modules that explicitly support TU510.
- PROFIBUS or CANopen interface arrangements whose selected communication module uses the D-sub connector.
- Panels standardized on spring-clamp field wiring.
- Service replacement where a wired base is retained separately from the plug-in communication module.
- Horizontal or vertical DIN-rail control-cabinet layouts within the AC500 system limits.
05
Lifecycle
- ABB lists standard order code 1SAP210800R0001 in the Active lifecycle phase.
- TU510-XC is a separate wide-temperature product with order code 1SAP410800R0001.
- Lifecycle records should associate the base with its plug-in module, protocol, network cable and terminal map.
- For service exchange, preserve the spring-terminal construction and verify the standard-versus-XC environment.
