Features:
- Serves legacy hydraulic-servo control duties in a Symphony Plus turbine system.
- Retains the SPHSS04 code for exact installed-base identification.
- Has SPHSS13 documented by ABB as the direct replacement model.
The current ordering configuration is SPHSS04, the legacy Symphony Plus hydraulic-servo module identified in ABB lifecycle material.
It supports the installed turbine valve-control interface whose feedback, output and tuning are defined by the project configuration.
Before replacement, capture wiring, LVDT type, servo polarity and control settings, then commission the ABB-designated SPHSS13 migration carefully.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Services an installed Symphony Plus hydraulic-servo channel in a turbine-control system.
- Supports maintenance of legacy valve-position feedback and drive circuits assigned to SPHSS04.
- Provides the installed-base reference for migration to ABB's SPHSS13 replacement module.
- ABB identifies SPHSS13 as the direct replacement for SPHSS04.
- The replacement statement also covers related IMHSS03, IMHSS04, IMHSS05, SPHSS03 and SPHSS05 modules.
- Project wiring, LVDT type and redundancy must still be checked for the installed application.
- The installed servo loop uses configured position feedback to track turbine-valve movement.
- Loop status and alarms depend on the associated Symphony Plus control strategy.
- Feedback direction and travel must be verified during post-replacement commissioning.
- The SPHSS04 page retains only legacy identity and installed-system facts supported by ABB.
- Performance claims published for SPHSS13 are not assigned retrospectively to SPHSS04.
- Actual loop response remains dependent on the field actuator, feedback device and configured tuning.
