Spring-terminal wiring base for eligible S500 analog and digital I/O modules.
TU516-H keeps field wiring on the terminal unit while a supported electronics module is removed, subject to ABB's module-index and powered-exchange conditions.
Hot swap is conditional: the electronics module index, I/O-bus master, firmware and field-energy state must all satisfy ABB's documented requirements.
Eligible modules, I/O-bus masters, live exchange, variants and order verification.
No. ABB TU516-H supports hot swap only for listed I/O modules at the permitted device index. Check the current ABB hot-swap table before removal or insertion.
No. ABB explicitly states that AC500-eCo CPUs do not support hot swap. Use a supported CI5xx master or PM56xx-2ETH processor with the required revision and firmware.
Unload digital outputs and switch off input or output voltages above SELV/PELV. Fully engage both module locks before restoring loads or field voltage.
ABB TU516-H provides up to 32 channel positions arranged as four groups of eight. The inserted I/O module determines the actual terminal assignment.
TU516-H order code 1SAP215000R0001 is the standard active hot-swap spring-terminal base. TU516-H-XC order code 1SAP415000R0001 is the active extreme-condition version.
