The **JR-6Z-R** is a specific model of a **6-Channel Wireless Remote Control Switch** (often used for industrial hoists, cranes, or agricultural machinery). It operates on a Radio Frequency (RF) system to toggle relays remotely. --- ## 1. Core Specifications Below are the primary electronic characteristics typical of the JR-6Z-R series: | Component / Feature | Specification | | :--- | :--- | | **Operating Voltage** | DC 12V - 24V or AC 110V - 220V (Model dependent) | | **Output Type** | Passive Switch Output (Dry Contact) | | **Max Load Current** | ≤ 10A per channel | | **Frequency** | 315MHz or 433MHz | | **Control Distance** | 50m - 100m (Open space) | | **Channels** | 6 Independent Channels | --- ## 2. Key Electronic Components The device consists of two main assemblies: the **Transmitter (Remote)** and the **Receiver (Main Board)**. ### A. The Transmitter (Remote Handset) * **RF Oscillator:** A Surface Acoustic Wave (SAW) resonator that stabilizes the frequency (usually 433.92MHz). * **Encoder IC:** (e.g., EV1527 or PT2262). This chip generates a unique digital code for each button press to prevent interference. * **Tactile Switches:** The physical buttons that close the circuit to trigger a signal. * **Battery Management:** Usually powered by a 12V 23A or 9V battery with a small LED indicator. ### B. The Receiver (Control Box) * **Superheterodyne/Super-regenerative Module:** The small vertical daughterboard that captures the RF signal from the air. * **Microcontroller (MCU):** The "brain" that decodes the signal from the transmitter and decides which relay to activate. * **Electromagnetic Relays:** The mechanical switches that click when you press a button. These allow a low-power signal to control a high-power motor or light. * **Step-Down Power Module:** Converts the input voltage (e.g., 220V AC) down to 5V or 12V DC to power the internal logic. --- ## 3. Working Modes The electronic logic on the board can usually be toggled between three modes using a **jumper pin** or a **learning button**: 1. **Inching (Momentary):** The relay stays closed only while the button is held down. 2. **Self-Locking (Toggle):** Press once for ON, press again for OFF. 3. **Interlocking (Latched):** Pressing one button turns ON channel A and automatically turns OFF all other channels. --- ## 4. Wiring Diagram Concept The receiver typically uses a terminal block for connections: ```text [ Power In + ] --> Connect to Power Source [ Power In - ] --> Connect to Power Source [ Relay 1: COM ] --> Common Line [ Relay 1: NO ] --> Normally Open (Load) [ Relay 1: NC ] --> Normally Closed (Optional) ... (Repeated for Channels 2 through 6) ```
