AAI141-H53_YOKOGAWA_PRODUCT_吉林易择科技技术发展有限公司

The Yokogawa AAI141-H53 is a high-density, single-channel, DC input isolating safety barrier designed for intrinsic safety (IS) applications. It provides protection for hazardous areas by limiting the energy (voltage and current) that can reach field devices. This model is specifically designed to convert input signals from 4-20 mA two-wire transmitters in the hazardous area into isolated and amplified 4-20 mA output signals for control systems in the safe area. The "-H53" suffix indicates it is optimized for ultra-high-density mounting on 35mm DIN rails.<br /> <br />
