Description
The FOXBORO E69F-TI2-S is a current-to-pneumatic signal converter designed for use in industrial process control applications. It converts a low-power electrical current signal (typically 4-20 mA) into a high-power pneumatic (compressed air) pressure signal (typically 3-15 psig).
Here’s a breakdown of its functionality and key points:
Function:
- The E69F-TI2-S bridges the gap between electronic control systems that use low-power current signals and pneumatic actuators that require compressed air for operation.
- It essentially amplifies and translates the weak electrical current signal into a proportional, high-power air pressure signal that can control the position or force of a pneumatic actuator.
Applications:
- Process Control Loops: Widely used in various process control applications across industries like:
- Chemical processing
- Oil and gas refining
- Pulp and paper production
- Power generation
- Food and beverage production
- Controlling Pneumatic Actuators: Used to regulate valves, dampers, and other pneumatic devices involved in controlling process variables like pressure, flow, temperature, and level.
Benefits:
- Signal Conversion: Enables seamless integration of electronic control systems with existing pneumatic actuators in industrial plants.
- Isolation: Provides electrical isolation between the control system and the potentially hazardous process environment where the pneumatic actuators operate.
- Simplified Maintenance: Offers a standardized interface for pneumatic actuators, simplifying maintenance and troubleshooting procedures.
Considerations:
- Supply Pressure: The E69F-TI2-S requires a compressed air supply for operation. Ensure your compressed air system provides the necessary pressure and flow rate for the converter to function properly.
- Calibration: The converter needs periodic calibration to maintain accurate signal conversion.
- Environmental Conditions: Consider the operating temperature and humidity range of the E69F-TI2-S to ensure it functions reliably within your process environment.
