The Pearl G-Series line of controls is designed to meet the environmental control requirements of most standard greenhouse applications. The different models are designed to match the complexity and requirements of the grower and are compatible with standard greenhouse equipment utilized by growers.
The unique design allows for greater expandability and flexibility for the grower. You can add input and output modules to expand to your specific requirements. With the integrated panel option, your controls can be mounted with the required contactors for easy installation and the assurance that your controls are connected properly.
The Pearl G-Series can be programmed at the controller with basic programming functionality or connect to the Link4 Cloud to enhance the operation of your controller. The Cloud offers the grower the ability to remotely control, monitor and receive alarm notification allowing you to stay connected to your operation while you are away.
User friendly screens allow you to easily program, change, and monitor all of your controllers that are connected to the Cloud from a single source. You will be able to assign users with specific access levels, add grower, or maintenance notes, or store photos, and assign tasks through the Cloud. In addition, you can identify important growing trends and ensure future crop success via insights gained using reports and graphs derived from data stored on the Cloud.
All Pearl model controllers are compatible with the Link4 Cloud allowing for remote accessibility and control, as well as added advanced features.
The Cloud allows you to view and operate your controller from remote locations at any time. Set up user security and accessibility per user and zone. View your current status and create custom reports, or download the data for further analysis. View any alarm status for your zones and receive notifications regardless of your location. With the Grow Journal and Task Manager, you can enter grower notes, photos or videos, and assign tasks as required.
Cloud pricing is monthly or a discounted annual fee based on the model and number of controllers.
