1-Channel 433MHz Wireless Remote Control Relay RF Transmitter 12VDC (A-B Function) - (AD40253)

Description:

This is a 433MHz remote control relay receiver module; the relay is activated by the remote control. In A-B function, when button A or B is pressed, the relay is activated as long as the button is held down, and when the button is released, the relay is deactivated. It is typically used in access control systems. Theoretically, the remote control distance is 100 meters. In real-world use, it is 10 to 30 meters; in open spaces without interference, the range can improve.

This module has a learning button on the relay receiver board. You can link multiple remote controls to a single receiver module, or vice versa, you can link a single remote control to multiple receivers.

For the remote with A-B function, both button A and button B must be linked separately. That is, you can link button A to one receiver and button B to another receiver.

Features:

- Wireless digital identification technology, each receiver module has a learning button, to link multiple remotes to multiple receivers.

- Wireless RF remote control, non-directional, the signal can pass through walls.

- No wiring required, saving wiring costs, time, and effort.

- Provides an SPDT relay, N.O. is normally open, COM is common, and N.C. is normally closed; equivalent to an ON-OFF, when the relay is energized N.O. and COM are connected.
