GE IS200TDBTH6ACD Discrete I/O Terminal Board

Product Brief Description

GE IS200TDBTH6ACD is a discrete contact I/O terminal board for the Speedtronic Mark VIe turbine control system. It serves as the interface between the PDIO I/O pack and field discrete devices, collecting digital contact feedback signals and outputting relay commands for turbine protection, interlock and auxiliary equipment control. The PCB adopts conformal coating for anti-corrosion and dustproof, designed for long-term stable operation in power plant turbine cabinets.

Product Functions

• Collect discrete contact input signals from field switches, limit switches and relays
• Provide Form-C relay outputs for trip, interlock and auxiliary drive control
• Signal isolation and surge suppression to protect core I/O pack circuits
• Terminal wiring interface for easy field connection and signal testing
• Transmit discrete data to PDIO pack via dedicated high-speed connector
• Conformal coated circuit board for harsh power plant environment
• Support TMR triple modular redundant control architecture of Mark VIe
• Onboard status LEDs for quick signal and fault diagnosis

Application Scenarios

• GE gas turbine, steam turbine and combined cycle unit control cabinets
• Power plant turbine protection, emergency trip and interlock control loops
• Oil & gas, chemical and metallurgy captive power generation units
• Mark VIe system spare replacement, overhaul and retrofit projects
• Auxiliary machinery control for boiler, generator and compressor
• Independent power plant and utility power station turbine control systems
