ABB Bailey · Symphony Plus HR Series

SPHSS13 Symphony Plus HR Series Hydraulic Servo Module

Valve-position control for properly engineered turbine hydraulic actuator applications.

Product Summary

ABB Bailey SPHSS13 is a Symphony Plus HR Series hydraulic servo module used as an interface between an HR Series controller and a hydraulic actuator command path. It can support servo-valve or current-to-hydraulic interfaces and uses valve-position feedback within an engineered turbine control solution. Typical control duties include steam-turbine throttle or control valves, gas-turbine fuel valves, inlet guide vanes and nozzle-angle mechanisms. It is suitable for documented maintenance, overhaul and spare-parts planning. Before ordering, confirm the controller arrangement, actuator type, feedback transducer, termination hardware, output requirement, supply voltages and complete label information.

Key Product Information

Functions and Technical Data Summary

• Provides a controller interface for hydraulic actuator valve-position control in HR Series turbine applications.
• Supports AC or DC LVDT feedback and a proportional-only operating mode when engineered for the application.
• Two servo output channels are rated up to ±300 mA; I/H output ranges are 4–20 mA or 20–160 mA.
• Four analog inputs include two LVDT secondary input pairs; two primary excitation outputs cover 400 Hz to 15 kHz.
• Includes three isolated digital inputs and one isolated digital output.
• Specified ambient operating range is 0 to 70 °C; module dimensions are approximately 35.56 × 177.80 × 298.45 mm.

Applications

• Steam-turbine throttle and control valve positioning.
• Gas-turbine fuel-valve positioning.
• Inlet guide-vane control in documented turbine systems.
• Nozzle-angle control within an engineered HR Series configuration.
• Non-modulating valve-position reporting when configured for that duty.

Compatibility and Revision Notice

SPHSS13 is application-dependent. Confirm the complete suffix, HR Series controller configuration, actuator type, LVDT wiring and excitation, servo-coil or I/H current requirement, termination hardware and supply arrangement.

• Verify the complete part number and suffix against the original nameplate.
• Confirm system generation, applicable voltage, field interface and termination arrangement.
• Confirm hardware revision and any firmware or software dependencies.
• Compare installation dimensions, target device requirements and existing wiring.
• Send clear photographs of the original equipment label and connector area.
