Isolated Analog Signal Converter 10V - 10V
The AC-10V-10V is an industrial precision analog signal conditioner and isolator engineered to provide 1:1 galvanic isolation for standard 0–10V DC voltage loops. Featuring a pure linear amplifier architecture with zero PWM conversion and zero digital reconstruction, it preserves original analog waveform fidelity with an ultra-fast response time of less than 1 ms and exceptionally low output ripple noise (< ±0.1%). With an ultra-high galvanic isolation barrier of 4.25 kV RMS between input and output, it breaks severe ground loops, protects expensive PLC/DCS analog input channels from common-mode voltage spikes, and eliminates electrical interference across noisy industrial automation environments.
