SPTPS13 1948506C8 ABB  Standard Wiring Method

Step 1 Power Supply Wiring

Connect 24 V DC positive and negative power cables to the dedicated power terminals on the module front terminal block; strictly distinguish positive/negative polarity to avoid module burnout. Add shielded twisted pair for power wire and connect cable shield to cabinet protective earth.

Step 2 Speed Sensor Signal Wiring

Run shielded two-core cables from turbine magnetic speed probes to the module speed input terminals; separate signal cables from high-power AC cables to avoid electromagnetic interference. Single cable length shall not exceed 500 meters.

Step 3 Digital Input Wiring (Mode Selection)

Wire external dry contact signals (Auto/Manual/Test) to 3 digital input channels; each input channel matches 24 V DC loop, install terminal fuses for short-circuit protection.

Step 4 Relay Output Wiring for Hydraulic Manifold

Connect 4 relay output terminals to hydraulic trip valve control loops; relay contacts are dry contacts without internal power supply, external control power must be configured separately.

Step 5 Protective Ground Wiring

Link the module ground terminal and cable shielding layer to the cabinet common protective grounding bar to eliminate static interference and improve signal stability.

Step 6 Pre-Power-On Inspection

1. Verify all wire sequences and polarity are correct, no short circuit between terminals.

2. Tighten all terminal screws to prevent poor contact under vibration.

3. Check cable shielding grounding integrity before powering on the module.

4. Complete offline speed simulation test to confirm overspeed trip function valid before formal turbine operation.

SPTPS13 1948506C8 ABB  Core Product Advantages

1. Multi-function Integrated Design: Combines speed counting, overspeed protection and hydraulic trip control, replaces three outdated modules to cut cabinet spare part inventory cost.

2. High-Speed Safety Response: Microsecond-level speed signal sampling, instant trip output within 8ms to prevent turbine over-speed damage.

3. Full Self-Diagnosis Function: Automatically detects open circuit, short circuit and abnormal amplitude of speed probes, triggers alarm signals for early maintenance.

4. Flexible Mode Switching: Supports automatic operation, manual test and offline calibration via digital input terminals, convenient for unit maintenance and commissioning.

5. Strong System Compatibility: Perfect plug-and-play match with Symphony Plus HR rack, no extra adapter board required for most upgrade projects.

6. Industrial-Grade Durability: Conformal coated circuit board resists dust, moisture and mild corrosive gas in power plant control rooms; long service life with low failure rate.

7. Standard Safety Certification: Compliant with IEC 61131-2, CE certified, meets power industry safety operation standards.
