RX-MULTI 300-868MHz Universal Multi-Frequency Receiver WITH 1 Remote Control – 2-Channel Relay Output for Gate, Door, Light & Alarm

RX-MULTI 300-868MHz Universal Multi-Frequency Receiver – 2-Channel Relay Output for Gate, Door, Light & Alarm

One Receiver, Dozens of Remote Controls – Fix 300–868MHz Rolling & Fixed Code Remotes

🔍 Description
Compatible with 300–868MHz remote controls. RX-MULTI universal receiver supports 8‑DIP switch frequency selection, 2 independent relay outputs (CH1/CH2), and easy pairing via S1/S2 buttons. Ideal for garage doors, gates, lights, motors, alarms, and access control systems. AC/DC 9–30V wide power input.

🚀 Product Overview
The RX-MULTI is a high-performance multi-frequency universal receiver designed to solve remote control compatibility problems.
It supports 300–868MHz frequency range, works with fixed code (2262/2260/1527/2240) and rolling code remotes from different brands.
With two independent relay channels (CH1/CH2), you can control two different devices with one receiver. Each channel has its own learning button (S1/S2) and supports momentary, toggle, and interlock working modes.

✅ Key Features
1️⃣ 8‑Bit DIP Switch – Brand Frequency Matching
Select the correct remote control brand/frequency via the 8‑position DIP switch
Compatible with 433.92MHz, 315MHz, 318MHz, 300MHz and more
Works with both fixed code and rolling code remotes

2️⃣ Two Independent Learning Channels
CH1 – S1 button
CH2 – S2 button
Each channel can learn multiple remotes independently
Output modes: Momentary / Toggle / Interlock (support customized)

3️⃣ Easy Remote Pairing (No remote needed for pairing)
Step 1: Set DIP switch to match your remote brand
Step 2: Press S1/S2 → LED lights up
Step 3: Press remote button → LED flashes 4 times → paired successfully

4️⃣ Wide Power Input & High Reliability
AC/DC 9V–30V (ideal for 12V/24V systems)
Standby current ≤10mA
Receiving sensitivity ≤‑110dB
Relay contact output (max 2500W load)

5️⃣ Erase All Remotes Easily
Hold learning button → LED turns on → keep holding until LED goes off → all stored remotes cleared

🧠 Quick Operation Guide
🔹 Pair a Remote (Add)
Set DIP switch to your remote brand (refer to included table)
Press S1 (for CH1) → LED lights up
Press your remote button → LED flashes 4 times → done
Repeat for CH2 using S2 button

🔹 Erase All Remotes Reset
Press and hold S1 or S2 → LED lights up
Keep holding → LED turns off automatically → all data erased

⚠️ This clears both channels.
