F&F AV-1I Voltage Transducer 0-282.8V AC / 0-400V DC to 4-20mA Output, 9-30V DC

The F&F AV-1I voltage transducer is a specialized industrial device engineered to convert input voltage signals into a standardized 4-20mA current output. It supports a wide range of inputs, accepting AC voltages up to 282.8V and DC voltages up to 400V. This transducer is designed to integrate seamlessly into automation systems, providing a reliable bridge between high-voltage measurement points and low-voltage control equipment like PLCs or data acquisition modules.

Advantages

The primary benefit of the AV-1I is its versatility in handling both alternating and direct current signals within a single compact unit. By converting variable voltage levels into a stable 4-20mA current loop, the device minimizes signal degradation over long cable runs, which is essential for maintaining accuracy in industrial environments. Its broad supply voltage range of 9-30V DC ensures compatibility with most standard industrial power supplies, while its robust design provides consistent performance in demanding monitoring applications.

Suitable for

• Industrial automation and process control systems
• Monitoring of electrical grid voltage levels
• Signal conditioning for PLC analog inputs
• Integration with data loggers and control instrumentation
• Energy management and diagnostic systems

This device may not be suitable for applications requiring high-frequency signal analysis or measurements involving non-standard waveforms that deviate from typical AC/DC characteristics. It is also not intended for direct connection to high-power loads or for use in environments where the input voltage exceeds the specified maximum thresholds.

Key specifications

• Input range AC: 0-282.8V
• Input range DC: 0-400V
• Output signal: 4-20mA current loop
