With this module, it is possible to connect to the controller, variable intensity pumps of 0-5V or 0 -/+ 10V type JEBAO (RW models only) and AQUAMEDIC.
 

The module allows the user to utilize the Controller and/or a PC (through a USB interface) to set up one or more programs that produce a dimmable wave or tide effect using the pumps connected to the system. 

The module permits connection to the pumps and replaces the controller. With its great flexibility, the system can reproduce a host of effects using various combinations of pumps at different times of the day.

Also, when connected to a day/night brightness sensor system (optional), it can automatically reduce pump operation to minimum speed during the night, which diminishes the wave action in the aquarium.
