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.
