GE DS200XDSAG1A Digital Signal Input Board for Mark V System

Product Description
DS200XDSAG1A is a digital signal input PCB board manufactured by GE, part of the GE Mark V turbine control system. This board collects discrete digital status signals from field devices, such as contact status of breakers, limit switches, relays and interlock contacts. It performs signal conditioning, optical isolation and level conversion, then transmits the processed digital signals to the main controller. The card adopts standard rack slot installation inside Mark V control cabinet, with built-in hardware fault detection. It is widely used as OEM spare replacement component for gas turbine, steam turbine and generator control systems in power plants.

Key Functions

• Multi-channel discrete digital input acquisition for field switch and relay contact signals
• Optical isolation circuit to suppress external noise and protect main control circuit
• Signal level conversion and debounce processing for reliable contact status reading
• Transmit digital status data to Mark V main controller via backplane bus
• On-board self-diagnosis for board hardware and input channel fault detection
• Designed for industrial cabinet environment with anti-vibration and EMI resistance
• Standard slot mounting inside GE Mark V turbine control rack

Application Scenarios

• GE Mark V gas turbine and steam turbine control system
• Power plant generator and combined cycle unit control cabinet
• Turbine interlock, breaker and auxiliary equipment status monitoring
• Mark V system spare parts replacement, maintenance and equipment retrofit
• Power generation control spare inventory backup
