ABB Bailey SPHSS13 Hydraulic Servo Module

Product Introduction

The ABB Bailey SPHSS13 is a highly specialized Hydraulic Servo Module designed for use in high-performance industrial automation systems, particularly in INFI 90 and Symphony distributed control architectures. As part of the Bailey I/O subsystem, this module acts as the intermediary between digital control logic and hydraulic servo mechanisms, enabling smooth, precise actuation in systems requiring fluid power control.

Engineered with ABB’s robust industrial design philosophy, the SPHSS13 is ideal for environments where precise valve positioning, fluid pressure regulation, and servo loop control are crucial. The module accepts digital or analog setpoints from the DCS and translates them into signals that control electro-hydraulic actuators, used in a wide range of critical process applications such as power plants, turbine control systems, and heavy-duty manufacturing.

The SPHSS13 delivers exceptional signal stability, fast response times, and fail-safe operation, making it indispensable in applications where hydraulic force needs to be regulated with electrical precision.

Frequently Asked Questions (FAQ)

1. What type of hydraulic actuators can be controlled using the SPHSS13?
   The SPHSS13 is designed to control electro-hydraulic servo valves, commonly used in turbine governors, presses, and industrial valve automation.

2. Is closed-loop control supported with feedback?
   Yes, the module supports analog feedback (e.g., 4–20 mA) for closed-loop servo control applications.

3. Can I use this module with third-party hydraulic systems?
   Yes, as long as the actuator accepts ±10 VDC or compatible control signals and provides feedback.

4. What is the module’s response time for output signal changes?
   The response time is typically under 2 milliseconds, enabling rapid system corrections.

5. Does it support Pulse Width Modulation (PWM)?
   Yes, PWM output is supported for compatible servo systems requiring it.

6. How does the module handle feedback loss or actuator faults?
   Feedback monitoring is built-in. If feedback deviates significantly or is lost, the module flags a fault condition via the LED indicator.

7. What type of signals can be used as command inputs?
   The SPHSS13 accepts standard analog command signals — 4–20 mA or ±10 VDC.

8. Can the module be integrated into safety-related loops?
   While not certified as a SIL-rated component, it can be incorporated into non-SIL safety-critical systems with external safety checks.

9. Does the module support configuration via ABB’s standard tools?
   Yes, it is configured using ABB’s DCS programming and diagnostic tools like Composer or CIU.

10. Can multiple SPHSS13 modules be installed in a single control rack?
    Yes, multiple SPHSS13 modules can be installed and independently operated within the same control system chassis.
