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.

The Pearl 8 Relay Output Module is a versatile control module designed for managing and optimizing agricultural environments such as greenhouses and grow rooms. It features eight relay outputs that can be configured for either wet or dry operation. In wet mode, each relay's high contact receives 24V power directly, while in dry mode, both contacts remain independent, requiring external equipment to provide power. Additionally, it includes eight digital inputs for external connections, allowing integration with switches like high-level tank indicators. Its built-in I2C interface supports various hardware sensors such as temperature and humidity sensors, ensuring comprehensive environmental monitoring. The module also features communication and power connectors to streamline power distribution within interconnected systems. Operating modes include Auto, Off, and Hand, with switch positions and system status easily accessible via the Pearl system's display. Ideal for efficient automation, it supports detailed monitoring and precise control for enhanced crop production.

The GEN 13 and GEN 14 Lighting Panels are pivotal for growers looking to optimize their greenhouse operations. These panels address critical safety concerns by integrating sensors that monitor temperature fluctuations and initiate an automatic shutdown if high temperatures are detected, thereby protecting crops from potential damage. Built with user-friendly switches, these panels facilitate easy operation and maintenance. Manufactured in California, these panels comply with UL safety standards and are permitted for use in the U.S. and Canada, making them a reliable choice for domestic and commercial growers alike. The GEN 13 panel supports up to 384 amps whereas the more robust GEN 14 supports up to 768 amps. A continual cooling fan further enhances product safety. As part of Link4 Corporation's innovative environmental controls, these panels work seamlessly with cloud-based systems to provide real-time data and alerts, empowering growers to maintain optimal growing conditions and respond swiftly to environmental changes.
