Description
Product Overview
The 24V Single-Channel Wireless Receiver Board is a professional-grade wireless control solution designed for seamless integration into 12V and 24V DC systems. This module serves as a bridge between a wireless remote and a DC-powered device, allowing you to control motors, pumps, LED lighting, access control systems, and other 24V equipment without complex wiring or programming .
The system includes a compact receiver board designed for DC 12V or 24V operation , paired with a 2-button A/B remote controller. The 433MHz wireless frequency ensures stable signal penetration through walls and obstacles, providing reliable control for industrial equipment, automation projects, and automotive applications .
Whether you are retrofitting existing machinery, building automated gates or barriers, or developing custom control systems, this module offers a simple, effective solution.
Key Features
-
DC 12V/24V Power Compatibility: The receiver is designed to operate on 12V or 24V DC power , making it ideal for automotive, industrial control, and battery-powered applications.
-
2A Relay Output: Features a built-in relay capable of switching loads up to 2A at 24V DC , suitable for controlling motors, solenoid valves, LED lighting, and other DC-powered equipment.
-
433MHz Wireless Technology: Operates on the 433.92MHz frequency band, offering better penetration through walls compared to 2.4GHz alternatives, with typical indoor range of 30–40 meters and up to 100 meters in open space .
-
Learning Code Technology: Utilizes EV1527 learning code technology , allowing secure pairing of multiple remotes without specialized programming tools. The receiver can store up to approximately 15 transmitters .
-
Multiple Control Modes: Supports multiple programmable operating modes including Momentary (Jog), Toggle (Self-Lock), and Latched modes, configurable via DIP switches or learning procedure .
-
A/B Remote Controller: The included 2-button remote allows control of a single receiver with two separate functions, or can be programmed to control two different receivers independently .
-
Compact Form Factor: Miniature PCB design (approximately 31mm × 15mm × 4mm) allows for easy integration into control cabinets, junction boxes, or custom enclosures.
-
Status Indicator: An onboard LED provides clear visual feedback for power status, relay activation, and learning mode confirmation .
