Features:
With the adoption of Optocoupler isolation, the power relay board can avoid high-voltage circuit interference.
The power relay board can avoid high-voltage circuit interference because of its adoption of Optocoupler isolation.
The weak current output by Raspberry Pi IO can be used to control the switching of strong current through power relay board, which is usually used in smart homes and other strong electric fields. It supports Raspberry Pi A+/B+/2B/3B.
9cm x 9cm x 3cm/3.54″ x 3.54″ x 1.18″ (Approx.)
notes:
Due to the light and the screen setting difference, the item’s color may slightly differs from the pictures. Please allow slight dimension difference due to the manual measurement. Raspberry Pi has 40-pin and 26-pin connectors. This product is only compatible with 40-pin connectors. The relay allows for the access to a power source up to 5A/250V AC or 5A/30V DC. The power relay board has four terminals, and each terminal has three pins for connecting external circuits. The Raspberry Pi GPIO interface is used to connect to the Raspberry Pi, and the relay screw terminal is used to connect to the target device. Attention: Relay indicator: LED lights up: relay NC is off, NO is on LED is off: relay NC is closed, NO is disconnected Relay control jumper: Short-circuit the jumper: control the relay through the standard I/O used in the sample code Disconnect the jumper wire: customize the I/O control relay through the jumper wire
