The ABB TY801 3BSE028112R1 features power-on maintenance-free capability. As an independent hardware component installed on the base (such as TU844/TU845), when unplugging or replacing a faulty I/O module (like AI880A/AI845), the field current signal continues to flow normally through the TY801 on the base. This ensures field transmitters maintain power, series connection circuits remain closed, and enables true physical-level, maintenance-free online hot-swapping without disturbance.
- Matching Bases: Termination units with separate slots including TU834, TU844 (redundant), TU845 (redundant), and TU854
- Supported I/O Modules: Primarily used with high-precision analog input modules AI845, AI880, and AI880A
