The 8-RELAYS card is a stackable expansion card for Raspberry Pi.
The card is compatible with all Raspberry Pi versions from Zero to 4.
It offers a compact and inexpensive solution for adding up to 64 RELAYS to your Raspberry Pi project.
Pluggable connectors make the 8-RELAYS card easy to use when multiple cards are stacked up.
Four relays with N.O. contacts can switch up to 8A/48VAC or 8A/24VDC.
The other four relays with N.O. and N.C. contacts and can switch 4A/120VAC or 4A/24VDC.
The 8-RELAYS card needs 5V to operate and can be powered from Raspberry Pi or from it's own 2.1mm barrel connector.
Status LEDs show when RELAYS are ON or OFF.

Command Line and Python Drivers
The 8-RELAYS cards share the I2C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards.
This feature leaves the remaining 24 GPIOs available for the user.
