### HORNETPRO-8S1: Technical Overview The **HORNETPRO-8S1** is a high-performance, industrial-grade remote control system operating on the 868MHz frequency. It is designed for rugged environments requiring reliable wireless switching. --- ### Core Electronic Specifications | Component / Feature | Specification Details | | :--- | :--- | | **Operating Frequency** | 868.35 MHz (FM) | | **Input Voltage** | 6V - 32V DC (Receiver) | | **Channels** | 1 Channel (Single output relay) | | **Switching Capacity** | 12A @ 230VAC / 10A @ 30VDC | | **Enclosure Rating** | IP68 (Waterproof/Dustproof) | | **Range** | Up to 2,000 meters (Line of Sight) | --- ### Key Internal Components #### 1. The Receiver (Main Board) The receiver utilizes **Narrowband FM technology**, which provides superior interference immunity compared to standard AM/ASK systems. * **Relay Output:** Features a high-quality mechanical relay with NO (Normally Open) and NC (Normally Closed) contacts. * **Learning Button:** An on-board momentary switch used to pair transmitters to the receiver using "Easy-Learn" technology. * **LED Indicators:** Visual diagnostics for power and RF signal reception. #### 2. Power Management The board contains an internal **switching regulator** that allows for a wide input voltage range (6V to 32V). This makes it compatible with both 12V and 24V vehicle/industrial systems without needing external step-down converters. #### 3. Security & Coding The system uses **KEELOQ Code Hopping** technology. * **Mechanism:** Every time a button is pressed, the transmitter sends a different encrypted code. * **Security:** This prevents "code grabbing" or "replay attacks" where a third party might try to intercept and copy the signal. #### 4. Antenna System The receiver typically features a pre-tuned wire antenna. However, for maximum range, the board includes a **U.FL or screw terminal connector** to allow the attachment of an external SMA antenna. --- ### Operational Modes The electronics can be configured via on-board jumpers or the learn process to operate in different logic modes: 1. **Momentary:** Relay is active only while the button is pressed. 2. **Latching:** Press once for ON, press again for OFF. 3. **Timed:** The relay stays active for a pre-set duration (typically several seconds to minutes). ---
