Yokogawa OpreX ™ STARDOM FCN-RTU Remote Terminal Unit

FCN-RTU, as a remote monitoring unit of Yokogawa STARDOM series, integrates four core capabilities of "remote data acquisition, distributed control, multi protocol communication, and low-power operation and maintenance", filling the gap of traditional RTUs in complex control and system compatibility. The specific functions cover:
Data acquisition: Supports analog (4-20mA, RTD/TC temperature), digital (24V DC switch signal), and pulse (flow counting, speed) acquisition, with a measurement accuracy of ± 0.1% FS, and supports channel level fault diagnosis (such as disconnection and short circuit detection);
Remote control: equipped with basic logic control (interlock protection, sequence control) and PID regulation functions, it can independently achieve localized control of remote stations (such as pump station pressure regulation, valve start stop), reducing dependence on the central system;
Narrow bandwidth adaptation: Supports narrow bandwidth communication such as GPRS/4G/LTE, satellite, microwave, etc. The data transmission adopts the "incremental upload+compression protocol" to reduce data consumption (such as compressing a single data upload to less than 1KB);
High reliability design: Key components (CPU, power supply, communication module) support redundant configuration, wide temperature range (-40~+70 ℃), anti-corrosion (G3 coating optional), anti vibration (5g/10-500Hz), suitable for unmanned harsh outdoor environments.
