1. Product Description

IS200SCLTH1A is a dedicated signal terminal board designed for GE Mark VI gas and steam turbine control systems. It serves as the intermediate wiring interface between field sensing devices, actuators and core control processor modules. Equipped with multiple screw terminal blocks, built-in signal filtering resistors, surge suppression circuits and internal signal routing traces, the board features reinforced industrial PCB material with anti-corrosion coating. It is installed inside the turbine control cabinet, matched with corresponding control core boards via flat ribbon cables, provides electrical isolation for low-voltage analog and discrete signals, and complies with power plant EMC, vibration and temperature standards for long-term stable operation under heavy industrial working conditions.

2. Core Product Functions

• Provide standard screw terminals for field wiring connection of analog signals, digital inputs and relay output circuits
• Transmit field measurement and interlock signals to main control boards through matched ribbon cable connectors
• Built-in RC filter circuits to suppress high-frequency electromagnetic noise from power plant equipment
• Integrated transient voltage suppression components to protect internal control circuits from lightning and grid surge damage
• Classified signal wiring layout to separate analog low-voltage lines and high-power control wiring to reduce interference
• Support quick disconnection and maintenance of field loops without removing core control cards from rack slots

• Conduct basic circuit shunt and signal distribution for turbine temperature, pressure, vibration and valve feedback signals

3. Application Scenarios

• GE Mark VI gas turbine control cabinets for combined cycle thermal power plants
• Steam turbine generator monitoring and interlock control system terminal wiring racks
• Industrial on-site gas turbine power generation skid control panels
• Petrochemical plant self-generation turbine unit safety monitoring cabinets
