Control Units

In modern aquaculture, especially in recirculating aquaculture systems (RAS), reliable controllers are essential for operational safety, resource efficiency, and the automation of key processes.

SENECT controllers provide a powerful platform for monitoring and regulating critical water parameters such as oxygen, pH, redox potential (ORP), water level, conductivity, CO2, and temperature. As part of a modular measurement and control system, they enable the flexible connection of numerous sensors and actuators.

Thanks to the modular design, the SENECT system grows with your facility. For functions such as filter cleaning, feeding, and aeration, precise threshold values can be defined per output – for example: start aeration when oxygen drops below 5 mg/l, stop at 10 mg/l.

SENECT controllers offer versatile operating modes for universal use:

• Time window control: Regulation only within defined time periods (e.g. 7 am–6 pm)
• Interval and timer control: Individual time settings for automated processes, including start time and duration
• Sensor-based control: Automatic regulation via individually adjustable threshold values (e.g. oxygen)
• Output coupling: Dependency on other actuators (e.g. raise skimmer before feeding)
• Versatile alarm options: Use of actuator outputs for warning lights, buzzers, etc.
• Smart feeder control with calibration and automatic feed quantity calculation
• Remote access and real-time monitoring via PC, smartphone or tablet

• Efficient monitoring and regulation of all relevant water parameters
• High operational safety through water level, motor current and system monitoring
• Reliable alarm systems via app, email, PLC or external signal devices
• Modular and future-proof: Easy expansion through plug-in connection technology
• User-friendly operation directly on the device or conveniently online
