F&F AC-1I 5A Current Transducer 0-5A Input 4-20mA Output 9-30V DC

The F&F AC-1I 5A current transducer is a precision-engineered device designed to convert alternating current inputs ranging from 0 to 5A into a standardized 4-20mA analog output signal. This transducer serves as a vital interface between high-current monitoring points and low-voltage control systems, ensuring that electrical parameters are accurately translated for processing by PLCs, data loggers, or industrial automation controllers. With a versatile power supply range of 9-30V DC, it integrates seamlessly into various industrial environments.

Advantages

The primary benefit of the F&F AC-1I 5A lies in its high measurement accuracy and reliable signal conversion, which prevents data loss in complex monitoring loops. Its compact design allows for efficient installation in crowded control cabinets, while the standardized 4-20mA output provides excellent immunity to electromagnetic interference over long cable runs. By utilizing this transducer, users can achieve precise real-time monitoring of electrical loads without the need for complex custom circuitry.

Suitable for

• Industrial automation and process control systems
• Energy management and power consumption monitoring
• Integration with PLC and SCADA systems
• Monitoring of electrical motors and heating elements

When it may not be suitable

This device is specifically designed for AC current measurement and will not function correctly with DC current inputs. It is also not intended for high-voltage direct measurement without appropriate current transformers if the primary current exceeds the 5A input range.

Key specifications

• Input current range: 0-5A AC
• Output signal: 4-20mA analog
• Supply voltage: 9-30V DC
• Signal conversion accuracy: High precision

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. Connect the AC current source to the input terminals of the transducer. Connect the 9-30V DC power supply to the designated power input terminals. Finally, wire the 4-20mA output signal to the analog input module of your PLC or monitoring device. Ensure all connections are secure and that the polarity of the DC supply and the output signal is correct before energizing the system.

What to consider before purchase

• Verify that your input current does not exceed the 5A limit
• Ensure your control system supports 4-20mA analog inputs
• Confirm that your power supply falls within the 9-30V DC range
• Check available space in your electrical enclosure for mounting

Usage recommendations

Always ensure that the current transducer is installed in a dry, dust-free environment to maintain long-term operational stability. Periodically verify the calibration of the analog signal loop to ensure continued measurement accuracy.
