Description
Woodward 8237-2596
Technical Specifications
- Part Number: 8237-2596
- Inputs: 8 discrete + 4 analog
- Outputs: 4 relay + 2 analog
- Bus Connection: High-speed expansion bus
Functional Features
- Scalability: Adds I/O capacity without additional voting processors.
- Diagnostics: Reports module health and I/O status to main processor.
- Hot-Swap: Supports module replacement without system shutdown.
Application Scenarios
Large turbine systems with extensive monitoring requirements or integrated compressor-turbine packages.
Performance Parameters
- Scan Time: <10 ms for all expansion I/O.
- Bus Speed: 10 Mbps.
Material Composition
Industrial-grade I/O components with robust bus interface circuitry.
Structural Characteristics
- Form Factor: Same width as standard ProTech-SX modules.
- Bus Connectors: Backplane connectors for daisy-chain expansion.
Working Principle
Communicates with the main voting processor over the expansion bus, providing additional I/O data and receiving control commands. All safety-critical voting remains in the main processor.
Installation Requirements
- Bus Termination: Install termination resistor at end of expansion bus.
- Address: Set unique module address before installation.
Usage Precautions
- Bus Length: Do not exceed maximum expansion bus length.
- Compatibility: Verify firmware compatibility with main processor.
