The **W2TS-N1Y-R2** is a high-performance **Programmable Digital Timer/Counter** manufactured by **Autonics**. It is designed for industrial automation and control systems, offering high precision and a compact form factor. --- ## 1. Core Technical Specifications The following table highlights the primary electrical and physical characteristics of the unit: | Feature | Specification | | :--- | :--- | | **Power Supply** | 100–240VAC 50/60Hz | | **Power Consumption** | Max. 5VA | | **Display Type** | 7-Segment LED (Red) | | **Digits** | 6-Digits | | **Output Type** | Relay Contact (SPDT) | | **Contact Capacity** | 250VAC 3A (Resistive Load) | | **External Power Supply** | 12VDC ±10%, 100mA | | **Protection Structure** | IP65 (Front panel only) | --- ## 2. Key Electronic Components & Subsystems ### A. Power Supply Unit (PSU) The device utilizes a wide-range **Switching Mode Power Supply (SMPS)**. This allows it to handle voltage fluctuations common in industrial environments (100V to 240V AC) without requiring external transformers. ### B. Microcontroller & Timing Circuit * **Precision:** The internal timing is driven by a crystal oscillator to ensure minimal error over long durations. * **Memory:** It contains non-volatile memory (EEPROM) that retains the count value and programmed settings during power failures. ### C. Input Interface The unit supports multiple input modes (NPN/PNP selectable via software or wiring): * **CP1 / CP2:** Signal inputs for counting or start/stop functions. * **RESET:** A dedicated input to clear the current value. * **Inhibit:** Stops the timing/counting process temporarily. ### D. Output Relay (R2 Model) The "R2" suffix specifically denotes the output configuration: * **Dual Relay Output:** It typically provides two independent relay contacts. * **Function:** These relays switch external loads (such as motors, solenoids, or signal towers) when the preset value is reached. --- ## 3. Terminal Configuration *Detailed wiring is essential for safe operation:* | Terminal No. | Function | Description | | :--- | :--- | :--- | | **1 - 2** | Source | Power Input (AC) | | **3 - 5** | Relay 1 | Common, NO, NC Contacts | | **6 - 8** | Relay 2 | Common, NO, NC Contacts | | **10** | +12VDC | External Sensor Power | | **12 - 14** | Inputs | CP1, CP2, and Reset signals | --- ## 4. Operation Modes The W2TS series is versatile because it can be electronically switched between two primary functions: 1. **Timer Mode:** Measures elapsed time or counts down (Supports units from milliseconds to hours). 2. **Counter Mode:** Counts pulses from sensors (Proximity, Photoelectric, or Rotary Encoders) with high-speed response (up to 5kcps/10kcps). ---
