Based on the technical specifications, the **CVR1-CH-R/CE** is a specialized electronic module typically used in industrial automation, power distribution, or specific sensory applications. Below is a breakdown of its electronic components and functional characteristics. --- ### 1. Component Overview The device is designed as a **Current/Voltage Monitoring Relay** or a specialized **Interface Module**. | Feature | Specification Details | | :--- | :--- | | **Category** | Industrial Control Component | | **Housing** | DIN-rail mountable (Standard 35mm) | | **Input Type** | Analog Voltage or Current signal monitoring | | **Output Type** | Relay Contact (typically SPDT or DPDT) | | **Compliance** | CE (Conformité Européenne) | ### 2. Key Electronic Parts & Functionality The internal circuitry generally consists of several functional blocks: * **Sensing Circuitry:** High-precision resistors and operational amplifiers used to sample the input voltage or current without significant power loss. * **Comparator Logic:** Microprocessor-based or analog comparator circuits that evaluate if the input signal exceeds or falls below the user-defined threshold (Setpoint). * **Adjustment Potentiometers:** Typically found on the front face, these allow manual adjustment of: * **Trip Point:** The specific level at which the relay triggers. * **Hysteresis (Differential):** Prevents "chattering" by requiring the signal to drop significantly before resetting. * **Time Delay:** Capacitors and timing ICs used to ignore momentary spikes. * **Relay Coil & Contacts:** The electromechanical part that provides physical isolation between the control circuit and the load. ### 3. Connection Interface The terminal block layout for this model usually follows a standardized industrial numbering: | Terminal Label | Description | | :--- | :--- | | **A1 / A2** | Power Supply Input (Auxiliary Voltage) | | **B1 / B2** | Monitoring Input (The signal being measured) | | **11, 12, 14** | Common, Normally Closed, and Normally Open relay contacts | ### 4. Safety and Standards (CE Marking) The `/CE` suffix indicates that the electronic parts meet the European Union's safety, health, and environmental protection requirements. This includes: 1. **EMC Compatibility:** Protection against electromagnetic interference. 2. **Low Voltage Directive (LVD):** Ensures insulation and physical safety of the electronic components. ---
