Product Description
Woodward 8237-1600 ProTech-GII HV/LV Overspeed Protection System
Voted Relays/Voted Inputs | 2-out-of-3 (2oo3) Safety Architecture | Turbine Overspeed/Overacceleration | IEC 61508 SIL 3 | Modbus RTU/TCP | On-line Maintenance
1. Core Product Overview
The Woodward 8237-1600 is a ProTech-GII HV/LV panel-mount overspeed protection system with voted relays/voted inputs (VR/VI), designed for steam, gas, and hydro turbines to prevent catastrophic overspeed/overacceleration events. It features a 2-out-of-3 (2oo3) voted architecture with dual redundant trip relays, enabling failsafe shutdowns, and supports HV/LV dual redundant power (24–250V AC/DC) for flexible industrial installations. The system integrates 3 magnetic pickup (MPU) inputs, 4–20 mA speed output, Modbus RTU/TCP communication, and H2S/SO2-resistant conformal coating (IEC 721-3-3 Class 3C2) for harsh 3C2 environments. It is panel-mountable with a backplane structure for on-line module maintenance, ensuring 24/7 protection in safety-critical turbine applications, complying with IEC 61508 SIL 3 standards{insert\_element\_0\_}.

3. Protection Logic & Safety Features
The 8237-1600 uses 3 independent MPU channels with 2oo3 voting to trigger dual redundant trip relays, ensuring safe turbine shutdown during overspeed/overacceleration. It monitors speed (0.5–32,000 RPM) and acceleration rate, with user-programmable overspeed setpoints (105–120% rated speed) and overacceleration thresholds (0.1–100 RPM/s). The system includes MPU open-line detection, overspeed test mode (internal generator), and event logging (1000 events) for post-trip analysis. Front-panel LEDs (Power: green; Channel Active: amber; Alarm: blue; Fault: red) and a fault relay enable on-site/remote monitoring, with H2S/SO2-resistant conformal coating for oil & gas/petrochemical environments.
• 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; on-line module repair • 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; automated periodic tests
4. Communication Protocols & Configuration
The 8237-1600 integrates with DCS/SCADA via Modbus RTU (RS-485) and Modbus TCP (RJ45), offering 4–20 mA analog output for direct controller interface. Configuration uses the **ProTech-GII Configuration Software** (Windows) for channel setup, filter parameters, setpoints, voting logic, and firmware updates, with front-panel DIP switches for basic addressing. It supports on-line module replacement via backplane structure, preserving config during hot-swaps, and integrates with Woodward DPG/DCS systems for centralized turbine control. The H2S/SO2-resistant conformal coating (IEC 721-3-3 Class 3C2) ensures reliability in sulfur-contaminated environments, typical of oil & gas and petrochemical applications{insert\_element\_1\_}.
• Protocols: Modbus RTU (RS-485); Modbus TCP (RJ45); 4–20 mA analog; relay outputs • Configuration: ProTech-GII Software; DIP switches; config backup/restore; on-line module replacement • Integration: DCS/SCADA; turbine governors; HMI; safety systems (IEC 61508 SIL 3) • Remote Access: Modbus diagnostics; event log download; firmware updates via TCP/IP
5. System Integration & Industrial Applications
The 8237-1600 mounts in standard 19-inch cabinets (panel mount) with plug-in terminals for power, MPU inputs, and outputs, integrating with DCS/SCADA via Modbus and 4–20 mA. 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. It complies with API 670, IEC 61508 SIL 3, CE, UL, and ATEX Zone 2 (optional), with a 12-month Woodward warranty and global technical support. The backplane structure allows on-line module maintenance, minimizing downtime during repairs/replacements{insert\_element\_2\_}.
