Description
Woodward 8200-182
Technical Specifications
- Channel Configuration: Mixed analog inputs, digital inputs, and relay outputs (specific to variant).
- Signal Types: Supports thermocouples, RTDs, 4-20mA, and dry contacts.
- Isolation: Galvanic isolation between channels and the backplane.
- Update Rate: Synchronized with the main processor scan rate.
Functional Features
- Scalability: Allows system expansion without replacing the main controller.
- Versatility: Software-configurable input types and output functions.
- Diagnostics: Detects open thermocouples, wire breaks, and short circuits.
- Hot-Swappable: Supports online replacement (system dependent) to minimize downtime.
Application Scenarios
Expanding I/O for auxiliary skids (lube oil, cooling water), remote panel monitoring, and additional protection relays.
Performance Parameters
- Accuracy: ±0.1% of full scale for analog inputs.
- Contact Rating: Relay outputs rated for 5A at 250 VAC.
Material Composition
Industrial-grade PCB with conformal coating. Gold-plated backplane connectors. Screw terminals or front connectors for field wiring.
Structural Characteristics
Standard module width for the target chassis. Front panel features per-channel status LEDs and terminal identification. Plugs directly into the backplane.
Working Principle
Conditions field signals, converts them to digital data, and transfers them to the main processor via the backplane bus. For outputs, it converts digital commands to relay states or analog currents.
Installation Requirements
Insert the module into an available slot and secure it. Configure the channel types in the control software to match the field wiring.
Usage Precautions
- Verify the power supply can handle the additional load.
- Ensure proper grounding of shielded field cables to prevent noise.
- Label all field wires clearly before connecting to the module.
