Woodward|9907-1290|Digital Turbine Control Module

Description

Features

• Multi-Protocol Communication: Supports Modbus RTU/ASCII and optional Ethernet for seamless integration with DCS/PLC systems.
• Dual-Mode Operation: Configures turbine parameters via CONFIGURE Mode (requires shutdown) or adjusts dynamics in real-time via SERVICE Mode.
• Safety-Rated Design: Compliant with API 670 standards for turbine protection, including 2-out-of-3 voting logic for trip block systems.
• Wide Input/Output Flexibility: Supports analog (4–20 mA) and digital signals for sensor/actuator integration.
• Hazardous Environment Compliance: Optional NEMA 4X enclosure for operation in corrosive or dusty industrial settings.
