Core Function
1. Signal Relay and Distribution
Multi-channel Signal Routing: Industrial-grade signal distribution is achieved through 16-24 relay contacts, supporting precise routing of control signals (such as start/stop commands and status feedback) to various turbine subsystems.
Enhanced Long-Distance Transmission: Built-in signal conditioning circuitry compensates for signal attenuation during long cable transmission, ensuring the integrity of 4-20mA analog or 24VDC digital signals.
2. Electrical Isolation Protection
Channel-to-Channel Isolation: Optocoupler isolation technology is used to achieve 1500V electrical isolation between the control side (EX2100 excitation system) and the load side (turbine actuator), preventing ground loop interference.
Surge Suppression: Integrated TVS diodes and RC snubber circuits protect against 6kV/3kA transient surges caused by motor startup/shutdown or lightning strikes.
3. System Protection Interaction
Fail-Safe Mode: When a control signal anomaly (such as overvoltage/undervoltage) is detected, the relay automatically trips, coordinating with the Mark V system to initiate an emergency shutdown.
Status Feedback: Real-time relay status feedback is provided to the DCS via dry contacts. RS485 and Modbus communication are supported.
DS200RTBAG2A core application areas
1. Power Energy System
Gas/Steam Turbine Control
As the core interface module of the Mark V control system, it directly drives the gas turbine ignition system and steam valve actuators to achieve speed regulation. In combined cycle power plants, it coordinates the interlocking control between the gas turbine and the waste heat boiler. In conjunction with the GE EX2100 excitation unit, it controls the generator field breaker via relay contacts, enabling rapid load shedding in the event of grid voltage anomalies.
2. Industrial Process Control
Petrochemical
This is used for reactor temperature interlock protection in catalytic cracking units. When the temperature exceeds 650°C, it triggers an emergency shutoff of the feed valve.
Metallurgical Manufacturing
Integrated into the blast furnace blower control system, it controls the redundant switching of the cooling water circulation pumps via a relay group, ensuring continuous operation in extremely cold environments as low as -25°C.
