The **CRS-16-R** is a specific model of a **Redundant Magnetic Latching Relay** or a specialized high-reliability power management component, often used in aerospace, defense, and mission-critical telecommunications. Below is a breakdown of the electronic parts and functional characteristics typically associated with the CRS-16-R series. --- ### 1. Key Technical Specifications | Parameter | Specification (Typical) | | :--- | :--- | | **Contact Form** | 16-Pole (16PST or 16PDT configurations) | | **Switching Mechanism** | Magnetic Latching | | **Control Voltage** | Usually 12VDC or 28VDC (Military standard) | | **Redundancy** | Dual-coil or redundant internal circuitry | | **Contact Rating** | High-current capacity (per pole) | --- ### 2. Internal Electronic Components The CRS-16-R is not a single component but an assembly of several critical electronic parts: #### A. Magnetic Latching Coils Unlike standard relays that require constant power to stay "On," the CRS-16-R uses **Latching Coils**. * **Set Coil:** A short pulse of current moves the armature to the closed position. * **Reset Coil:** A pulse moves it back. * **Benefit:** Zero power consumption in the steady state and high resistance to shock/vibration. #### B. Redundant Circuitry (The "R" Suffix) The "R" often denotes **Redundancy**. Inside the housing, there are often dual coils or mirrored contact sets. If one control circuit fails, the backup circuit ensures the switch can still be toggled. #### C. Contact Materials The contacts are typically made of **Silver-Cadmium Oxide** or **Gold-Plated Tungsten**. These materials are chosen for: * Low contact resistance. * Prevention of contact welding under high-inrush currents. * Long-term oxidation resistance. --- ### 3. Functional Architecture #### Switching Logic The unit operates using a pulse-width command. It ignores continuous signals to prevent overheating. ```mermaid graph LR A[Input Pulse] --> B{Control Logic} B --> C[Set Coil] B --> D[Reset Coil] C --> E[Mechanical Latch] D --> E E --> F[16-Channel Output] ``` #### Housing and Shielding * **Hermetic Sealing:** The electronic parts are encased in a vacuum-sealed or nitrogen-filled metal can to prevent arcing at high altitudes. * **EMI Shielding:** Integrated metal casing prevents Electromagnetic Interference from affecting the low-voltage control signals. --- ### 4. Applications * **Satellite Power Distribution:** Switching large banks of solar array power. * **Avionics:** Managing redundant flight control systems. * **Defense Systems:** Decoupling sensitive electronics from power sources during storage.
