WOODWARD I/O modules are electronic components designed to facilitate communication and data exchange between various devices and systems within a control system, particularly those used in power generation and industrial applications. These modules provide the interface between the controller and external devices such as sensors, actuators, and human-machine interfaces (HMIs).

Key Functions

Signal conditioning: Convert analog or digital signals to a format that can be processed by the controller.
Isolation: Provide electrical isolation between the module and other system components to prevent interference and protect equipment.
Data acquisition: Collect data from various sensors and instruments.
Output control: Send control signals to actuators and other output devices.
Alarm generation: Trigger alarms based on predefined conditions.

Product Parameters (Typical)

Number of channels: The quantity of input or output channels per module.
Input/Output types: Analog (voltage, current), digital (discrete), or specialized (e.g., thermocouple).
Signal range: The minimum and maximum values that can be measured or controlled.
Resolution: The level of precision in the measurement or control.
Accuracy: The deviation of the actual value from the desired value.
Response time: The time it takes for the module to respond to a change in the input.
Isolation: The degree of electrical isolation between the module and other parts of the system.
Communication protocols: Supported protocols (e.g., Modbus, Profibus, Ethernet).

Product Advantages

Versatility: Capable of interfacing with a wide range of devices and systems.
Reliability: Designed for rugged industrial environments.
Customization: Can be configured to meet specific application requirements.
