Description Module13.2 4Relay v1.1 is a relay module with 4 mechanical relay control channels (NO, COM) onboard. The module uses the I2C communication protocol for control, effectively saving IO resources. The jumper cap design allows switching between active and passive working modes to meet different circuit requirements. This relay module only supports DC circuit switching, with a maximum load capacity of 24W (DC 24V @ 1A) per channel. It includes external power supply voltage detection and a DC-DC circuit to power the host. It is suitable for controlling the switching of small load circuits. Features STM32G030F6 I2C communication (addr: 0x26) 4 relay control channels, maximum load capacity 24W (DC 24V@1A) Supports two working modes (active and passive) Voltage detection Compatible with Arduino, UIFlow, and other programming platforms Includes 1 x Module13.2 4Relay v1.1 5 x 2.54mm-2P terminal blocks (green) 10 x jumper caps 1 x wiring manual Applications Solenoid valve control DC circuit switching Specifications Specification Parameter MCU STM32F030F4P6 Communication Interface I2C Communication @0x26 Supported Working Modes Active Control / Passive Control Relay Channels 4x (COM, NO interface) Power Input Interface DC5521 female jack 5.5 x 2.1mm@5-24V (inner positive, outer negative) Load Capacity Maximum load capacity 24W (DC 24V@1A) per channel Relay Terminal Block 2.54-2P Single Relay Power Consumption 5V@40mA Coil Activation Time 6ms Coil Release Time 4ms Product Size 54.0 x 54.0 x 19.7mm Product Weight 38.0g Package Size 134.0 x 95.0 x 20.0mm Gross Weight 58.1g Learn and Documents → DOCUMENTS
