Woodward 9907-149 is a high-reliability digital interface module, primarily used to enable communication and signal conversion between Woodward controllers (e.g., governors, protection modules) and external systems. Below is its detailed information:
- Brand: Woodward
- Model: 9907-149
- Product Type: Digital interface module
- Series Affiliation: Classified under Woodward’s 9907 series, a product line dedicated to industrial control system connectivity and signal integration.
- Core Purpose: Acts as a "communication bridge" to resolve signal incompatibility between different devices, supporting data transmission and control command synchronization.
- Input Voltage: 24V DC (nominal), with an operating range of 18V DC – 32V DC to tolerate industrial power fluctuations.
- Power Consumption: Typical current draw of 0.3A at 24V DC (no load), low energy consumption for continuous operation.
Supports multiple industrial-standard protocols to adapt to different system architectures:
- Primary Protocols: Modbus RTU (via RS-485), CANopen, and Ethernet/IP.
- Secondary Interfaces: RS-232 (for local configuration and debugging) and a 2-wire isolated RS-485 port (for long-distance communication, up to 1200 meters).
- Data Transfer Rate: Up to 1 Mbps (for CANopen/Ethernet/IP), ensuring high-speed real-time data exchange.
- Digital Inputs: 8 isolated 24V DC inputs (dry contact/normally open), with short-circuit protection for detecting status signals (e.g., valve open/closed, system ready).
- Digital Outputs: 4 isolated relay outputs (Form C, 24V DC/5A), used to trigger external devices (e.g., alarms, contactors).
- Analog Inputs: 2 differential 4-20 mA inputs (12-bit resolution) for monitoring analog signals (e.g., pressure, temperature).
- Analog Outputs: 2 isolated 4-20 mA outputs (12-bit resolution) for sending control signals to actuators.
- Dimensions: Approximately 140mm (L) × 90mm (W) × 50mm (H), compact to fit standard control cabinets.
- Mounting: DIN rail mounting (compatible with EN 50022 standard rails), enabling quick installation and replacement.
- Operating Temperature: -40°C to +70°C, suitable for harsh environments like power plants, oil refineries, and marine facilities.
- Humidity: 5% – 95% (non-condensing), no performance degradation in high-humidity conditions.
- Protection Class: IP20 (front panel), requiring installation in enclosed cabinets to prevent dust/water ingress.
- EMC Compliance: Meets IEC 61000-6-2 (industrial immunity) and IEC 61000-6-4 (emissions), avoiding interference with other devices.
- Multi-Protocol Compatibility: Supports Modbus, CANopen, and Ethernet/IP, eliminating the need for additional converters when connecting to different systems.
- Isolation Design: All inputs/outputs and communication ports are electrically isolated (2.5kVrms), preventing ground loops and voltage spikes from damaging the module.
- Easy Configuration: Configurable via Woodward’s Toolkit Software (PC-based), allowing users to set protocol parameters, map I/O signals, and save/load configurations.
- Diagnostic & Fault Tolerance:
- Status LEDs for power, communication, and I/O faults (e.g., red for communication failure, green for normal operation).
- Built-in watchdog timer to reset the module automatically if it malfunctions, ensuring system reliability.
- Redundancy Support: Optional dual power supply inputs (18V DC – 32V DC) for critical applications requiring uninterrupted operation.
- Turbine Control Systems: Connects Woodward governors (e.g., 505 series) to DCS/SCADA systems for remote monitoring and control of turbine speed/load.
- Power Generation: Integrates genset controllers with plant management systems to synchronize power output and log operational data.
- Marine & Offshore: Links propulsion system controllers to ship automation systems, ensuring stable communication in marine environments.
- Industrial Automation: Facilitates signal exchange between PLCs, sensors, and Woodward protection modules (e.g., ProTech-GII) in chemical, oil, and water treatment plants.
- Availability: New units are typically in stock, with a lead time of 4–6 business days for global delivery.
- Recommended Accessories: DIN rail clips, RS-485 communication cables, and Woodward Toolkit Software (free download from the official portal).
- Official Resources: Refer to the 9907 Series Interface Module Technical Manual (Document No. 8507-XXXX) for wiring diagrams, configuration guides, and troubleshooting steps.
