Features:
- Provides turbine protection, frequency counter, and turbine speed assessment operating modes.
- Consolidates the documented functions of the earlier SPTPS02, SPFCS01, and SPTSA01 modules.
- Supports dedicated termination hardware selected for the configured speed-measurement or protection role.
The current ordering configuration is SPTPS13, the ABB Symphony Plus Turbine Protection System Module for Harmony Rack turbine-control applications.
SPTPS13 processes speed-sensor signals for protection, frequency measurement, or turbine speed assessment according to its selected operating mode and function-code configuration.
Before replacement, match the operating mode, TPTU02 or NTDI termination, probe characteristics, function-code mapping, and trip-circuit design to the installed system.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Performs triple-redundant turbine overspeed protection when configured in the Turbine Protection System operating mode.
- Measures frequency and rotational speed signals for control-system monitoring in Frequency Counter Service mode.
- Supports turbine speed assessment and probe-condition supervision in Turbine Speed Assessment mode.
- Executes turbine protection independently of the controller and communication highways when configured for protective service.
- Uses triple-redundant inputs and two-out-of-three voting to improve availability of the overspeed trip decision.
- Detects open- or short-circuit probe conditions when operating with the documented turbine speed assessment configuration.
- Pairs with the TPTU02 termination unit when configured for the turbine protection operating mode.
- Uses NTDI01 or NTDI02 termination hardware for documented frequency-counter and speed-assessment applications.
- Requires the function-code selection and point mapping to match the operating role being replaced in the Harmony Rack system.
- Controls termination-unit relay outputs that initiate the configured turbine protective action.
- Supports online testing within the documented triple-redundant protection arrangement without disabling all protection channels.
- Requires verification of trip logic, sensor wiring, termination assignment, and plant proof-test procedures before service.
