yo tambien encontre información todo en ingles. segun lo poco que entiendo es una especie de microprocesador para anejar grandes y poderosos aparatos (industriales tal vez) pero desde controles remotos. es como una especie de receptor controlador.
The Fisher ROC306 and ROC312.
Small in size. Big in performance.
Power for the Toughest Applications. The Fisher Type ROC306 and Type ROC312 Remote Operations Controllers (ROCs) are powerful microprocessor-based remote measurement and control devices. They are ideal for low to medium point-count applications requiring sophisticated measurement and control capability. They incorporate many outstanding features that make them easy to use, easy to customize to the application, and cost-effective for current and future needs.
Easy to Use. The ROC306/ROC312 feature versatile firmware that makes complex calculations, like those for gas flow measurement, simple to implement. Both AGA orifice and turbine metering calculations are pre-programmed. Likewise, sophisticated PID loop control and logic sequencing control schemes can be implemented without programming.
