Unit Relay

SKU:U023

Description

Unit Relay is a single-channel relay control high-voltage driving unit. It is based on the HK4100F-DC5V-SHG relay and provides SPDT (Single Pole Double Throw) switching, supporting high-voltage on/off control up to AC 220V@3A / DC 30V. This unit is directly driven by a single GPIO logic level and features physical isolation as well as a status indicator LED. It communicates via a Grove HY2.0-4P interface and adopts a LEGO-compatible hole design, enabling flexible integration with LEGO structures or screw mounting. It is suitable for safe power management scenarios in smart homes, appliance control, and automation equipment.
