The **R7HL-YV2-R/F2K** is a specific module within the **OMRON R7HL Series** of Remote I/O terminals. These are primarily used in industrial automation environments to facilitate communication between a central controller (like a PLC) and field devices via the **CompoNet** network. --- ## 1. Technical Specifications The R7HL-YV2-R/F2K is a **Voltage Output** expansion module. Below are its primary electronic characteristics: | Feature | Specification | | :--- | :--- | | **I/O Type** | Analog Output (Voltage) | | **Number of Points** | 2 Points (2 Channels) | | **Output Range** | 0 to 10 V, -10 to 10 V, 0 to 5 V, 1 to 5 V | | **Resolution** | 1/6,000 (Full Scale) | | **Network Protocol** | CompoNet | | **External Power Supply** | 24 VDC | | **Current Consumption** | 100 mA max at 24 VDC | | **Conversion Time** | 2 ms / 2 points | --- ## 2. Key Electronic Components & Interfaces ### A. Output Circuits The module uses Digital-to-Analog Converters (DACs) to translate digital signals from the PLC into precise voltage levels. * **Isolation:** The output signals are typically optically isolated from the internal logic circuits to prevent surges from damaging the controller. * **Accuracy:** It maintains a high degree of precision, typically ±0.3% to ±0.5% of the full scale at room temperature. ### B. Connection Terminals The unit utilizes a **2-tier terminal block** system: 1. **Communications Connector:** For the CompoNet flat or round cable. 2. **External Power Terminals:** Provides power for the internal electronics and the output drive. 3. **Analog Terminals:** Labeled for Channel 0 and Channel 1 (V+, V-, and Shield). ### C. DIP Switches Located under the front cover, these hardware switches allow for manual configuration: * **Node Address:** Setting the identity of the unit on the network. * **Output Range:** Defining whether a channel operates at 0-10V or 1-5V, etc. --- ## 3. Practical Applications This module is typically used to control devices that require a variable voltage signal rather than a simple On/Off state: * **VFDs (Variable Frequency Drives):** Controlling the speed of a motor. * **Proportional Valves:** Regulating flow or pressure in hydraulic/pneumatic systems. * **Actuators:** Precise positioning of mechanical arms or louvers. --- ## 4. Installation Safety Note > [!IMPORTANT] > Ensure the external 24 VDC power supply is Class 2 or reinforced insulation type to meet safety standards. Always ground the **GR (Ground)** terminal to minimize electromagnetic interference (EMI) which can affect analog signal stability. ---
