The Three 40A/240V Relays RS485 Daisy-channable HAT is designed for use with the Raspberry Pi. It features three heavy-duty relays that can handle up to 40A and 240V each, suitable for controlling three-phase industrial loads. The card can be daisy-chained up to 32 units through an RS485 port and is equipped with pluggable connectors, an on-board processor, and LED indicators
It's compatible with all Raspberry Pi versions from Zero to 5. The card requires a 12V power supply and includes reverse power supply protection, a reset push-button, DIN-Rail mounting brackets and screws. It also supports software self-test and comes with all necessary mounting hardware.
