3. Detailed Product Description:
The WOODWARD 8200-1104 serves as a cornerstone for robust digital monitoring in complex industrial processes managed by Woodward control systems (such as the 505XT or MicroNet systems via an appropriate gateway). As part of the RTCnet series, it excels in demanding environments and offers the advantages of a distributed I/O architecture.
Here’s a closer look at its features and function:
- 16 Discrete Input Channels: This module provides a high density of input points, allowing it to monitor a significant number of binary signals from the field. These signals typically originate from:
- Limit switches: Indicating mechanical positions (e.g., valve fully open/closed, damper position).
- Pressure switches: Detecting pressure thresholds.
- Flow switches: Indicating liquid or gas flow presence.
- Level switches: Monitoring tank or reservoir levels.
- Relay contacts: Providing status feedback from protective relays or other control circuits.
- Operator pushbuttons/switches: For manual inputs or acknowledgements.
- RTCnet Communication: The module communicates over Woodward’s RTCnet protocol. This is a robust, high-speed, and deterministic CAN-based communication network. RTCnet enables these I/O modules to be strategically placed throughout the plant, closer to the sensors. This significantly reduces the amount of field wiring, minimizes noise interference, and enhances system flexibility and troubleshooting.
- Signal Integrity and Isolation: The 8200-1104 is designed to ensure clean and reliable signal acquisition. It typically includes electrical isolation for its inputs, which protects the sensitive control circuitry from ground loops and electrical noise originating in the field wiring. This is crucial for maintaining system stability and preventing damage.
- Integration with Control Systems: The module provides the main control system with real-time status updates from the field. This digital input data is vital for:
- Sequential Control: Advancing through startup, shutdown, and operational sequences.
- Interlocks and Permissives: Ensuring safe operation by verifying conditions before allowing certain actions (e.g., “valve must be closed before pump starts”).
- Alarming and Annunciation: Triggering alerts when abnormal or critical states are detected.
- Protective Trips: Initiating emergency shutdowns if critical safety conditions are met.
This module is a cost-effective solution for applications requiring extensive digital monitoring, providing a robust and reliable interface between the plant floor and the control logic.

5. Typical Applications:
The WOODWARD 8200-1104 is widely utilized in industrial applications where comprehensive monitoring of on/off conditions is critical for automated control, safety, and operational efficiency:
- Gas and Steam Turbines: Monitoring various valve open/closed positions, breaker status (e.g., generator breaker), pump run/stop status, permissive signals for startup/shutdown sequences, and emergency stop button activation.
- Compressor Stations: Detecting valve limit switch states, filter high-pressure alarms, and motor overload trip signals.
- Process Control: In chemical plants, refineries, and other industries, monitoring the status of motors, pumps, fans, conveyors, safety interlocks, and numerous other discrete conditions.
- Balance-of-Plant Control: For monitoring auxiliary systems within power generation or large industrial facilities.
