Structure and Composition

Signal Processing Layer

• Input channels are equipped with photoelectric isolation + Schmitt trigger shaping, supporting 10kHz high-speed counting (for speed sensor signals).
• Output channels use MOSFET solid-state relays with no mechanical contacts, boasting a lifespan of 5 million operations.

Communication Layer

• Exchanges data with the Mark VIe controller via the IS200ERMG fiber optic communication card, offering excellent EMI interference resistance.
• Front panel bicolor LEDs provide real-time communication status indicators (green = normal, red = fault).

Power Supply Layer

• Dual 24V DC redundant power supply, supporting hot-swap switching with a power-off hold time >10ms.

Key Features and Advantages

• Excitation system-specific design: Passed IEEE C37.90.1 surge immunity testing, directly driving circuit breaker opening/closing coils.
• Fiber optic redundant communication: Dual-channel fiber optic links (single-mode/multi-mode optional) eliminate signal loss caused by electromagnetic interference.
• Ultra-high-speed response: 1ms input scanning + 2ms output response, meeting grid requirements for <5ms fault clearing.
• Contactless output: Solid-State Relays (SSR) with no mechanical wear, suitable for frequent operation scenarios (e.g., AVR adjustment).
• Intelligent diagnostics: Monitors channel health status via ToolboxST software, enabling predictive maintenance of contact lifespan.

Application Fields

• Gas turbine excitation control: Status monitoring and control of synchronous generator field circuit breakers (GCB).
• Grid black start: Cooperates with the DS200LDCCH1A excitation regulator to achieve rapid voltage establishment.
• Steam turbine protection: Drives emergency stop solenoid valves (ESV) in response to OPC (overspeed protection) signals.
• New energy grid connection: Rapid switching control of SVG devices in wind/solar power plants.

Installation and Maintenance

Pre-installation Preparation

• Use a fiber optic end-face detector to check the cleanliness of ERMG card interfaces (to avoid dust-induced scattering loss).
• Ensure the rack grounding resistance is <1Ω, and install EMI conductive gaskets between the module and cabinet.
• Prepare a 24V DC redundant power supply (e.g., DS200PSAG).

Maintenance Recommendations

• Test fiber optic link attenuation with an optical power meter every 12 months (should be <3dB).
• Regularly check output channel load current (must not exceed 0.5A) to prevent MOSFET overheating.
• When replacing the module, download configurations online via ToolboxST; direct hot-swapping is prohibited.
