The **XIB-R** is a specialized wireless receiver unit typically used in industrial automation, security systems, or remote control applications. It is designed to interface with various transmitters to trigger specific electronic outputs. Below is a breakdown of its core electronic components and technical specifications. --- ## 1. Internal Electronic Architecture The XIB-R functions as a bridge between radio frequency (RF) signals and electrical circuits. | Component | Function | | :--- | :--- | | **RF Module** | Receives incoming wireless signals (usually at 433MHz or 868MHz) and demodulates them. | | **Microcontroller (MCU)** | The "brain" that decodes the signal, checks for security IDs, and manages the logic. | | **Relay Switches** | Physical switches that open or close a circuit based on the signal received. | | **Terminal Blocks** | Connection points for power input (VDC/VAC) and dry contact outputs. | | **LED Indicators** | Visual feedback for power status, signal reception, and programming mode. | --- ## 2. Technical Specifications Most XIB-R modules share a similar electronic profile designed for reliability in harsh environments. ### Power & Connectivity * **Operating Voltage:** Typically 12V to 24V AC/DC. * **Current Consumption:** Low standby current (approx. 15-20mA), increasing when relays are active. * **Frequency Range:** Standardized RF bands (e.g., 433.92 MHz). ### Output Configuration * **Channels:** Usually 1 or 2 independent channels (Relays). * **Contact Type:** Normally Open (NO), Normally Closed (NC), and Common (COM). * **Contact Rating:** Often rated for 1A to 5A at 30V DC or 125V AC. --- ## 3. Operational Modes The electronics are programmed to handle signals in three primary ways: 1. **Pulse (Momentary):** The relay remains closed only as long as the transmitter button is pressed. 2. **Latch (Toggle):** Press once to turn the relay ON; press again to turn it OFF. 3. **Timed:** The relay activates for a pre-set duration (e.g., 3 seconds for a gate trigger). --- ## 4. Safety and Interference Parts * **Antenna Terminal:** A specific port to connect a whip or tuned antenna to increase range. * **Pairing Button:** A tactile switch on the PCB used to synchronize the receiver with new transmitters. * **EEPROM:** Non-volatile memory that stores the IDs of paired transmitters even after a power loss. ---
