RK802 4-Channel Industrial RF Receiver Controller

Industrial 4-channel RF receiver for multi-device control

The RK802 is an independent MCU-programmed 4-channel industrial RF receiver controller designed for wireless control of multiple devices from a compact receiver unit. It is suitable for industrial control panels, automation equipment, remote switching projects, motor accessories and multi-output RF control systems.

With four control channels, the RK802 can manage several devices or command outputs from one receiver. It is a practical solution when installers need centralized RF control without building a custom receiver board from scratch.

MCU-programmed control logic

The independent MCU platform helps support reliable channel handling and project-specific control logic. This makes the receiver useful for OEM projects, replacement control boxes and industrial systems that need repeatable wireless switching behavior.

The product uses RF wireless networking and is specified for a 30-100m control distance in open space. Actual performance depends on the remote transmitter, receiver placement, antenna position, enclosure material and surrounding interference.

Designed for 10A / 36V applications

The RK802 is rated for up to 10A maximum current and 36V maximum voltage. This makes it suitable for low-voltage switching and control applications where several outputs need to be handled in one receiver.

Before installation, confirm the connected load, switching current, voltage range and duty cycle. For inductive loads such as motors, relays or solenoids, appropriate protection and system-level testing are recommended.

Typical applications

- Multi-device industrial remote control

- Lighting, relay and auxiliary equipment switching

- Motor accessories and low-voltage automation control

- OEM control panels and retrofit receiver boxes

- RF control systems for workshops, machines and project equipment

- Centralized receiver control for multiple independent outputs

Practical installation design

The plastic housing keeps the receiver compact and easy to place inside equipment panels or control enclosures. The single-item package format is convenient for sample testing, maintenance supply and small-batch project builds.

For best performance, mount the receiver where the RF signal is not shielded by heavy metal structures. Test the complete transmitter-and-receiver set in the real installation environment before final production or handover.
