Description
Product Description
The ABB SPHSS03 is a 3‑channel hydraulic servo module for ABB Symphony Plus DCS, designed for Harmony Rack turbine control to enable precision position, speed, and force control of hydraulic actuators in power generation and heavy industry. The ABB SPHSS03 uses closed‑loop feedback with 0‑10 V/4‑20 mA analog inputs and <5 ms response time, achieving ±0.01 mm positioning accuracy for critical turbine valve control. It supports 24 V DC (±15%) power, 500 V AC isolation, and -20°C to +60°C operation, ideal for harsh industrial settings. The ABB SPHSS03 integrates with ABB 800xA and legacy INFI 90/Symphony Harmony systems, ensuring seamless retrofits and multi‑vendor compatibility. It features LED diagnostics, removable terminals, and DIN rail mounting, simplifying troubleshooting and maintenance. The ABB SPHSS03 also supports 2/3 voting for TMR systems, meeting API 670/612 turbine safety standards. Its conformal coating and ESD protection make the ABB SPHSS03 a reliable choice for gas/steam turbine and industrial motion control applications.

Selection Suggestions and Precautions
- Selection Suggestions:
- Choose the ABB SPHSS03 for Symphony Plus/Harmony Rack‑based turbine control needing API 670/612 compliance.
- Opt for it if your system requires 3‑channel precision control and <5 ms response time.
- Select the ABB SPHSS03 for retrofits of INFI 90/Symphony Harmony systems to ABB 800xA.
- Precautions:
- Ensure compatibility with ABB Harmony Rack and 24 V DC power supplies (±15%).
- Use shielded cables and proper grounding to maximize signal integrity with the ABB SPHSS03.
- Follow ESD protocols during installation to protect the module’s electronics.
- Validate feedback sensor compatibility (0‑10 V / 4‑20 mA) before commissioning.
