The **W2TS-1BC-R2/CE** is a high-precision, industrial-grade weighing transmitter (often referred to as a signal conditioner or load cell amplifier) manufactured by **WAN-S**. It is designed to convert analog signals from load cells into standardized digital or analog outputs for PLC or PC integration. --- ### 1. Core Technical Specifications Below is a breakdown of the primary electronic characteristics: | Feature | Specification Details | | :--- | :--- | | **Power Supply** | 24V DC (Standard industrial voltage) | | **Input Signal** | 0.5 ~ 3.0 mV/V (Compatible with most strain gauge load cells) | | **Excitation Voltage** | 5V DC (Supports up to 4x 350Ω load cells in parallel) | | **Output Type** | Dual output (Analog + Digital/Relay options depending on sub-model) | | **A/D Resolution** | High speed, typically 24-bit internal processing | | **Mounting** | DIN Rail (35mm) for control cabinet installation | | **Certification** | CE Marked (Compliance with European safety/EMC standards) | --- ### 2. Key Electronic Components & Functions #### A. Signal Conditioning (Analog Front-End) The "R2" designation often refers to the internal relay or communication configuration. This part uses a high-precision **Instrumentation Amplifier** to boost the micro-voltage signals (mV) from a load cell into a workable range. It includes built-in filters to reduce electronic noise from industrial motors or VFDs. #### B. Digital Conversion It utilizes a high-resolution **Analog-to-Digital Converter (ADC)**. This ensures that the physical weight being measured is converted into a digital value without losing accuracy due to quantization errors. #### C. Connectivity & Communication * **RS-485 Modbus RTU:** Usually the primary digital communication protocol, allowing multiple units to be daisy-chained to a single PLC port. * **Analog Retransmission:** Can provide 4-20mA or 0-10V signals representing the weight value. --- ### 3. Application Use Cases The electronic design of the W2TS series makes it suitable for: 1. **Tank/Silo Weighing:** Monitoring inventory levels in large containers. 2. **Platform Scales:** Converting mechanical force into readable digital data. 3. **Process Control:** Using the internal relays to trigger "High" or "Low" weight alarms for automated filling systems. --- ### 4. Wiring Overview * **Terminals 1-4:** Usually dedicated to the Load Cell (Excitation +, Excitation -, Signal +, Signal -). * **Terminals 5-6:** 24V DC Power Input. * **Communication Ports:** Dedicated pins for RS-485 (A/B) or Analog Output.
