woodward 8200-1302
Product Name
Woodward 8200-1302 Series 505D Digital Governor Turbine Control (Integrated HMI, Marine/ATEX Compliant, 18–32 VDC).
Product Description
The Woodward 8200-1302 is a microprocessor-based digital governor/turbine control unit belonging to the Series 505D family, engineered for precise speed, load, and sequencing control of steam, gas, and hydro turbines in power generation, marine propulsion, and industrial rotating machinery applications. It features an integrated graphical front panel HMI for local monitoring and configuration, with built-in auto-start sequencing (hot/cold starts), critical speed avoidance across three speed bands, overspeed trip monitoring, zero-speed detection, and time-stamped trip/alarm logging for audit and troubleshooting. Equipped with configurable analog/digital I/O and RS-485 (Modbus RTU) communication, it seamlessly integrates with actuators, sensors, and SCADA/DCS systems. Rated for 18–32 VDC (typical 24 VDC) and designed for harsh industrial/marine environments, it supports mission-critical operation with redundant speed sensing and fail-safe trip logic, making it ideal for marine (IACS UR E10-compliant) and ATEX-certified hazardous area deployments.
Key Parameters & Specifications (Consolidated & Verified)
| Category | Specification | Notes (Discrepancy Alert) |
|---|---|---|
| Manufacturer | Woodward | Series 505D Digital Governor Turbine Control |
| Model/Part Number | 8200-1302 | Not a standalone I/O or servo module; integrated governor with HMI |
| Product Type | Digital Governor/Turbine Control with integrated HMI | Marine/ATEX-compliant variant |
| Power Supply | 18–32 VDC (typical 24 VDC); isolated | Third-party 18–36 VDC claims are for other variants; use 18–32 VDC per 505D specs |
| Power Consumption | ≤15 W (typical @ 24 VDC); ~0.6 A @ 24 VDC | Derate for extreme temps |
| Speed Inputs | Dual redundant magnetic pickup (MPU)/hall effect sensors (0.5–30 VAC) | For overspeed protection and speed feedback |
| Speed Range & Accuracy | Configurable (e.g., 300–10,000 RPM); ±0.25% rated speed (typical) | Third-party 500–3000 RPM is application-limited, not hardware max |
| Analog I/O (Typical) | Inputs: 4–20 mA (loop-powered), 0–5 VDC, 0–10 VDC; Outputs: 2× 4–20 mA (control outputs) | Configurable for setpoints, load feedback, actuator drive |
| Digital I/O (Typical) | ~10 alarm DI, ~10 trip DI, 8× Form-C relay outputs (programmable for alarms/trips/status) | Third-party 16 D |
