THE CONTROL EXPANDER
The CtrlBot is an expansion module that enhances the capabilities of the GroLab™ system, enabling independent control of up to 10 actuators at 12/24VDC and significantly increasing automation possibilities in horticultural environments.
Designed to directly manage irrigation zones, lighting systems or other electrical devices, CtrlBot offers personalised control of distinct electrical lines, easily adapting to the specific needs of each project. Its compatibility with relays and power contactors simplifies the control of electrical panels, even in medium or large installations.
CtrlBot stands out for its flexibility by integrating a wide range of peripherals, from solenoid valves and water pumps to high-power ventilation and lighting systems, making automated management more efficient and comprehensive.
The purchase of sensors, peripherals, and replacement parts compatible with the GroLab™ system can be made through the Open Grow online store or via GroLab™ resellers.
The installation below demonstrates the versatility of CtrlBot. In this example, the module directly controls 12VDC devices, such as five dosing pumps and a solenoid valve used to fill a tank. By using relays, it is also possible to control higher-power equipment such as an HPS ballast and an extractor. This flexibility makes CtrlBot ideal for large-scale fertilisation, irrigation, ventilation and lighting systems.
