Woodward 8200-1311
Product Name: Woodward 8200-1311 505XT Digital Governor (HVAC/DC, Ordinary Locations)
Product Introduction: A high‑voltage AC/DC variant of the 505XT controller, replacing legacy 505E HV models. It integrates generator synchronization logic and is optimized for turbine‑generator sets.
Technical Specifications:
- Power Supply: 88–264 VAC / 90–150 VDC (high‑voltage AC/DC)
Detailed content
- Speed Input: Dual MPU inputs (100–24,950 Hz)
- Communication: Independent RS‑232 and RS‑422 ports, Modbus RTU/TCP
- I/O: Configurable analog/digital I/O; supports generator PT/CT sensing
- Operating Temp: −40°C to +70°C; Weight: ~3.2 kg
- Compliance: CE, RoHS, UL 1998
Functional Features:
- Integrated generator frequency/phase/voltage matching for synchronization
- Supports isochronous load sharing and soft load transfer
- Low‑current PWM output for actuator control
- Field‑configurable speed/load setpoints via analog or discrete inputs
- Optional transient smoke limiter for turbocharged engines
Application Scenarios:
- Steam/gas turbine‑generator sets (standalone/parallel operation)
- Industrial engine control (diesel/gas) for pumps and compressors
- Power generation plants and cogeneration systems
- Upgrades of legacy 505E high‑voltage control systems
