SPDSI13 ABB Bailey DI Module

Application Scenarios of ABB SPDSI13 in Process Automation

1. Power Plant Protection System

• Location: Combined-cycle gas turbine (CCGT) plant in Sweden
• Function: Monitors 240VAC/24VDC contactor status (A5E32362953 & A5E35328464) through 32-channel isolated inputs
• Critical Role: Triggers circuit breaker (A5E35283013) within 35ms upon detecting grid fault signals
• Environmental Specs: Operates at IP54 enclosure rating with -25°C to +55°C tolerance

2. Steel Mill Safety Interlocks

• Integration: Paired with ABB AC 800M DCS in rolling mill controls
• Signal Processing: Handles 500A HECT current sensor inputs (A5E38507829) via burden resistors (A5E01473390)
• Redundancy: Dual-module configuration achieves SIL3 compliance per IEC 61508

3. Marine Propulsion Control

• Vessel Type: LNG carrier dynamic positioning system
• Key Parameters:
  • 19-30V DC operating range for damper actuators (A5E45095153)
  • <1.8mA leakage current prevents false triggering in humid environments
• Maintenance: Module replacement interval >50,000 hours (MTBF
