Product Description
Foxboro output modules are electronic devices used in distributed control systems (DCS) to convert electrical signals from a controller into physical outputs, such as controlling valves, motors, or other actuators. These modules are essential components in industrial automation systems, providing the interface between the control system and the process.
Key Features and Specifications
Types of Outputs:
Analog outputs: Convert electrical signals into analog voltages or currents to control analog devices like valves or variable speed drives.
Discrete outputs: Provide on/off signals to control relays, solenoids, or other digital devices.
Special outputs: For specific applications, such as frequency outputs for motor control.
Signal Conditioning: Many modules offer built-in signal conditioning to ensure compatibility with various field devices.
Isolation: Galvanic isolation is often provided to protect the control system from electrical noise and faults.
Communication: Connect to the controller via various communication protocols, such as HART, Foundation Fieldbus, or proprietary protocols.
Mounting: Typically DIN rail or panel mountable for easy installation.
