Product Description
Woodward 8237-1369 ProTech-GII Overspeed Protection System
HV/LV Power | 2-out-of-3 Voted Relays | Turbine Overspeed/Overacceleration | IEC 61508 SIL 3 | Modbus RTU/TCP | Panel Mount
1. Core Product Overview
The Woodward 8237-1369 is a ProTech-GII configurable overspeed protection system for steam, gas, and hydro turbines, designed to safely shut down rotating equipment upon overspeed or overacceleration events{insert\_element\_0\_}. It uses a 2-out-of-3 (2oo3) voted relay architecture for dual redundant trip outputs, ensuring failsafe turbine protection, and offers high/low voltage (HV/LV) power input compatibility for flexible installation{insert\_element\_1\_}. The system provides 4–20 mA speed readouts, Modbus RTU/TCP communication, and H2S/SO2-resistant conformal coating (IEC 721-3-3 Class 3C2) for harsh industrial environments{insert\_element\_2\_}. It is panel-mountable, supports hot-swappable modules (5437-1119), and complies with IEC 61508 SIL 3 for safety-critical turbine applications{insert\_element\_3\_}.
• Core Role: Turbine overspeed/overacceleration protection; 2oo3 voted trip; shutdown supervision; speed monitoring; Modbus remote diagnostics • Model Info: 8237-1369 (order code); ProTech-GII series; HV/LV power; 2oo3 voted relays; panel mount • Key Specs: 2oo3 voting; dual redundant trip relays; 4–20 mA speed output; Modbus RTU/TCP; -40°C~+70°C • Reliability: Conformal coating (3C2); hot-swappable modules; IEC 61508 SIL 3; IP20; 100,000-hour MTBF
2. Key Technical Specifications
| Parameter | Specification |
|---|---|
| Safety Architecture | 2-out-of-3 (2oo3) voted relays; dual redundant trip outputs; independent alarm relays |

| Speed Input | 3 magnetic pickup inputs; 1–100,000 RPM; 100 Hz–10 kHz frequency range |
| Outputs | 2 trip relays (NO/NC, 5A/250V AC); 4–20 mA speed output (0–120% rated speed); alarm relay |
| Communication | Modbus RTU (RS-485); Modbus TCP (RJ45); 9.6–115.2 kbps baud rate |
| Environment | -40°C~+70°C; 5–95% non-condensing; IEC 721-3-3 Class 3C2 (H2S/SO2 protection) |
| Mechanical | Panel mount (250×180×100mm); 1.2 kg; hot-swappable module (5437-1119); IP20 |
3. Protection Logic & Safety Features
The 8237-1369 uses 3 independent speed measurement channels with 2oo3 voting to trigger dual redundant trip relays, ensuring safe turbine shutdown during overspeed/overacceleration{insert\_element\_4\_}. It monitors speed (1–100,000 RPM) and acceleration rate, with user-programmable overspeed setpoints (105–120% rated speed) and overacceleration thresholds (0.1–100 RPM/s){insert\_element\_5\_}. Front-panel LEDs (Power: green; Channel Active: amber; Alarm: blue; Fault: red) and a fault relay enable on-site/remote monitoring, with event logging (1000 events) for post-trip analysis{insert\_element\_6\_}. It also supports overspeed test mode via internal generator, and open-line MPU detection for sensor fault protection.
• Protection Logic: 2oo3 voting; overspeed (105–120% rated speed); overacceleration (0.1–100 RPM/s); MPU fault detection • Redundancy: 3 speed channels; dual trip relays; independent power/communication; hot-swappable modules • Monitoring: 4–20 mA speed output; LEDs; fault relay; event log; Modbus remote diagnostics • Testing: Internal overspeed test; MPU open-line detection; relay contact monitoring
3. Communication Protocols & Configuration
The 8237-1369 integrates with DCS/SCADA via Modbus RTU (RS-485) and Modbus TCP (RJ45), offering 4–20 mA analog output for direct controller interface{insert\_element\_7\_}. Configuration uses the **ProTech-GII Configuration Software** (Windows) for channel setup, setpoints, voting logic, and firmware updates, with front-panel DIP switches for basic addressing{insert\_element\_8\_}. It supports hot-swappable 5437-1119 modules in ProTech-GII racks, preserving config during replacement, and integrates with Woodward DPG/DCS systems for centralized turbine control{insert\_element\_9\_}. It also features conformal coating for H2S/SO2 resistance, making it suitable for oil & gas and petrochemical applications{insert\_element\_10\_}.
• Protocols: Modbus RTU (RS-485); Modbus TCP (RJ45); 4–20 mA analog; relay outputs • Configuration: ProTech-GII Software; DIP switches; config backup/restore; hot-swap retention • Integration: DCS/SCADA; turbine governors; HMI; safety systems (IEC 61508 SIL 3) • Remote Access: Modbus diagnostics; event log download; firmware updates via TCP/IP
4. System Integration & Industrial Applications
The 8237-1369 mounts in standard 19-inch cabinets (panel mount) with plug-in terminals for power, MPU inputs, and relay outputs, integrating with DCS/SCADA via Modbus and 4–20 mA{insert\_element\_11\_}. It is ideal for power generation (thermal/hydro/wind), oil & gas, petrochemical, and industrial cogeneration—where IEC 61508 SIL 3-compliant overspeed protection is critical{insert\_element\_12\_}. It complies with CE, UL, ATEX Zone 2 (optional), and IEC 61508 SIL 3, with a 12-month Woodward warranty and global technical support{insert\_element\_13\_}. It also offers a seamless upgrade path to ProTech-GIII (same size/connections) for future expansion.
