Product Name

Core Functions & Technical Positioning

1. Relay-Based Control & Protection
• High-Current Relays: Features 10 relays (7 high-current relays with form C contacts and state indicator lamps) for triggering critical actions like turbine shutdowns, valve actuation, and alarm signaling.
• Emergency Trip Control: Integrates three sets of emergency trip relays (ETR) and two sets of primary trip relays (PTR) to execute mechanical/electrical overspeed tests, TMR cross-trip tests, and other safety protocols.
2. Signal Conditioning & Isolation
• Optical Isolation: Provides 2000V Hi-Pot isolation and 1500V transient common-mode rejection to protect against voltage surges and electromagnetic interference.
• Genius Bus Communication: Supports configurable data rates (38.4–153.6 kbaud) for real-time data exchange with other Mark V modules over a daisy-chained bus.
3. Flexible Configuration
• Jumper Selectable Settings: Allows adjustment of relay coil voltages (120V DC, 115V AC) and control power sources via hardware jumpers.
• Modular Integration: Connects to the LTB (Lan Terminal Board) via a 16-pin connector (RPL) and 2-pin optical connector (OPT PL) for expanded I/O functionality.

Technical Specifications

Application Scenarios

1. Turbine Control Systems
• Steam/Gas Turbines: Executes emergency trips during overspeed events, monitors vibration thresholds, and controls lubrication systems.
• Wind Turbines: Manages grid synchronization and blade pitch adjustments to optimize energy output.
2. Process Automation
• Oil & Gas: Triggers shutdowns in response to pressure/flow anomalies in pipelines or refinery units.
• Power Generation: Coordinates with SCADA systems for load shedding and grid stability during faults.
3. Safety-Critical Environments
• Nuclear Facilities: Supports SIL 2/3-rated safety systems by providing redundant trip paths and fault logging.
