4 Channel Relay Wireless Module

This is a 4 channel relay modulewhich can be controlled by a wireless remote through a wireless RF link.Thewirelessboard can operate within a range of 50m when the remote is in line of sight and around 25m when indoors. The RF link on this board works on the 433 MHz frequency.

How to link the 4 channel relay with remote?

• To link the remote and relay, power relay board, hold down the button for about 1 second to learn to let go.

• Learn indicator light flashes, press the button on the remote control to learn indicator light flashes after a few off, both represent learning success.

Features:

• Control: Allows wireless control of up to four separate electrical devices or appliances.
• Voltage: Operates on a DC 12V power supply.
• Output: Each relay can handle loads up to 10A.
