Link4 Corporation products

The Pearl Controller, designed by Link4 Corporation, is engineered to enhance greenhouse management by accommodating over 100 inputs and outputs through customizable expansion modules. It supports a variety of control types, including On/Off for valves, Proportional for vents, and Analog for VFD fans. A significant feature is its use of Modbus communication which allows for up to 4,000 feet of daisy-chained connections, reducing wiring complexity compared to conventional methods. These modules can be efficiently mounted on a DIN rail or distributed as per facility requirements. The design supports easy module integration with the Link4 Bus system, ensuring neat installations, while external connections are managed via plugs. Additionally, it is compatible with sensors operating on a 0-10V scale. This allows for precise environmental monitoring and management, promoting efficient environmental control. In conjunction with Link4's cloud-based control systems and sensors, users can optimize crop growth conditions remotely.
