Link4 Corporation - Pearl 8 Relay Output Module for Greenhouse Control

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.
