RSOS 433MHz 2-Channel Remote Control Relay Receiver Kit

Wireless relay control for doors, gates and switching projects

The RSOS remote control relay receiver kit is designed for simple wireless switching in garage doors, access control systems, lighting, small motors and other low-voltage control projects. It combines a compact receiver with matching remote transmitters, giving installers a ready-to-use solution for remote on/off or channel control.

This product is suitable for applications that need dependable short-to-medium range control without a complex network setup. The receiver can be used in residential, commercial and light industrial environments where a handheld remote is the most practical control method.

315MHz and 433MHz learning-code compatibility

The kit supports common 315MHz and 433MHz RF configurations, with learning-code encoding for convenient pairing. Available remote modes include lock/unlock, A/B, one-key and on/off options depending on the selected kit configuration.

Learning-code pairing helps simplify setup and makes the receiver suitable for replacement, upgrade and OEM control projects. For best compatibility, confirm the required frequency, remote button logic and receiver output behavior before installation.

Practical 2-channel relay output

The 2-channel receiver layout makes it useful for controlling two independent loads or two command directions. Typical control logic can include open/close, forward/reverse, start/stop, lock/unlock or separate channel switching depending on the connected equipment.

The compact white plastic housing helps protect the receiver electronics while keeping installation straightforward in control boxes, door systems and small electrical enclosures.

Typical applications

- Garage door and gate remote control

- Door access and lock/unlock switching

- Lighting and small equipment remote switching

- Motor forward/reverse or two-command control systems

- Alarm, safety and automation auxiliary control

- OEM wireless relay receiver kits for compact products

Installation and integration notes

The working range is specified at approximately 50-100 meters in open space. Actual range depends on receiver placement, antenna orientation, enclosure material, wall obstruction and surrounding RF interference. For stable performance, install the receiver away from large metal surfaces and high-voltage equipment when possible.

The receiver should be matched with the correct transmitter frequency and coding type. Before production or final installation, test the complete transmitter-and-receiver set under the real site conditions and load requirements.
