Process Control Signal Interface Features
The Yokogawa AAI135-H50/13S00 receives field analog signals and converts them into digital process data for Yokogawa FIO architectures. The module supports direct installation in ESB bus node configurations and optical ESB bus node configurations.
Furthermore, the module design follows Yokogawa process control I/O architecture requirements, including channel-to-channel isolation for separating field input circuits. Therefore, the module reduces signal interference between independent analog measurement loops.
The module architecture supports process instrumentation signals commonly applied in DCS environments. In addition, Yokogawa analog input modules can integrate with transmitter loops using standard process signal interfaces such as 4-20 mA current transmission depending on system configuration.
