Structured mounting and field termination for documented ABB automation assemblies.
ABB TU516 is an S500 I/O terminal unit for analog and 24 V DC digital modules in AC500 automation assemblies. Its spring-terminal connection system provides field wiring through forty signal and process-supply terminals while the inserted I/O module interfaces with the station I/O bus. The terminal unit supports up to thirty-two channels arranged in four groups and permits an I/O module to be removed without disturbing the fixed field wiring. TU516 is suited to new panels, modular I/O extensions and maintenance replacement. Verify the exact model, inserted module, 24 V DC process supply, terminal assignments and mounting arrangement before ordering.
