| Specification | Details |
|---|---|
| Model/Part Number | 9566-850 |
| Manufacturer | Woodward |
| Description | ProAct Digital Speed Control System for Diesel/Gas Engines |
| Series | ProAct |
| Function | Regulates engine speed, supports load sharing, and controls ProAct actuators |
| Processor | Microprocessor-based (specific architecture not publicly detailed) |
| Memory | Flash: 4–8 MB (for firmware and configuration) RAM: 2–4 MB (for runtime data) |
| Display | No onboard display; LED indicators for status and faults; configuration via external PC or HMI |
| Inputs | 2 speed inputs (magnetic pickup or proximity probes, 0.5–25 kHz) 4 analog inputs (4–20 mA or 0–5 V, e.g., remote setpoint, load sensor) 4 discrete inputs (24 VDC, for start/stop, reset, or mode selection) |
| Outputs | 1 actuator output (0–200 mA, compatible with ProAct actuators) 2 analog outputs (4–20 mA, for speed or load monitoring) 3 relay outputs (dry contact, up to 250 VAC/2 A, for alarms or trips) |
| Communication Interfaces | 1 serial port (RS-232 or RS-485, Modbus RTU) 1 CANbus port (for engine ECU or system integration) USB (for configuration and diagnostics) |
| Control Modes | Isochronous, droop, variable speed, load sharing |
| Speed Regulation Accuracy | ±0.25% of rated speed (steady-state) |
| Protection Functions | Overspeed protection, actuator fault detection, loss of speed signal |
| Redundancy | Non-redundant |
| Diagnostics | Fault detection, event logging (up to 100 events), status LEDs, real-time monitoring via Modbus or CANbus |
| Compatibility | Woodward ProAct actuators (e.g., ProAct I, II, III, IV), magnetic pickups, proximity probes, engine ECUs (via CANbus); third-party devices via Modbus RTU; integrates with Woodward control systems (e.g., EasyGen, 505) and SCADA systems |
