The Sequent Microsystems 8 Relays 4A/120V 8-Layer Stackable HAT for Raspberry Pi is a versatile expansion board designed to enhance the functionality of Raspberry Pi models ranging from Zero to 5. This HAT features eight relays, each capable of handling 4A at 120VAC or 24VDC, providing robust control for various applications. The relays are equipped with both normally open and normally closed contacts, along with LED indicators for easy status monitoring.

This stackable HAT can be layered up to eight times, allowing for a total of 64 relays, making it suitable for complex projects requiring extensive relay control. It includes an RS485 port and supports integration with command line interfaces, Python, and Node-RED, offering flexibility for developers and hobbyists alike. The HAT also supports Home Assistant and OpenPLC, and includes a CODESYS driver, enhancing its utility in automation and control systems.

The board is designed to use only the I2C port, leaving all GPIO pins available for other uses. It features pluggable connectors compatible with 26-16 AWG wires, ensuring secure and reliable connections. The inclusion of a general-purpose push-button and software self-test capabilities further enhances its functionality and ease of use.
