Based on the part number **FRTD-R-1G-LS/Q**, this component belongs to a specific family of **RTD (Resistance Temperature Detector) Transmitters** or **Resistance-to-Current Transducers**, often used in industrial automation for precise temperature monitoring. Below is a breakdown of the electronic specifications and part nomenclature: ### 1. Part Number Breakdown | Component Segment | Meaning | Description | | :--- | :--- | :--- | | **FRTD** | Functional Group | RTD (Resistance Temperature Detector) input module. | | **R** | Output Type | Typically indicates a **Relay** output or a specific **Resistance** conversion type. | | **1G** | Range/Configuration | Often represents a specific temperature range or a **1-Channel Galvanic** isolation. | | **LS** | Connection/Power | Low Signal or specific Loop-powered Supply configuration. | | **Q** | Quality/Certification | Often denotes "Quick-connect" terminals or specific industrial quality standards. | --- ### 2. Key Electronic Features This device serves as a bridge between a physical sensor (RTD) and a control system (PLC/DCS). * **Input Compatibility:** Designed to interface with Platinum RTDs (like Pt100 or Pt1000). It measures the change in resistance as temperature fluctuates. * **Galvanic Isolation:** The "1G" designation usually implies that the input, output, and power circuits are electrically isolated. This prevents ground loops and protects sensitive PLC inputs from high-voltage surges. * **Signal Conversion:** It converts the non-linear resistance of the RTD into a standardized linear industrial signal, such as: * 4-20 mA (current loop). * 0-10 V DC. * **Mounting:** Typically designed for **DIN Rail** mounting (35mm) within industrial control panels. --- ### 3. Technical Specifications (Typical) | Feature | Specification | | :--- | :--- | | **Input Type** | 2, 3, or 4-wire Pt100 RTD | | **Standard Output** | 4-20 mA DC | | **Supply Voltage** | 24V DC (typical for LS models) | | **Accuracy** | ±0.1% of span | | **Response Time** | < 200 ms | | **Operating Temperature** | -20°C to +60°C | --- ### 4. Application Use Case This part is used in environments where precise temperature measurement is critical, such as: 1. **Chemical Processing:** Monitoring reactor temperatures. 2. **HVAC Systems:** High-precision air duct monitoring. 3. **Food & Beverage:** Ensuring pasteurization temperatures remain constant.
