To wire the digital inputs on the Unitronics V200-18-E2B Snap-In Input-Output Module, follow these steps:
1. **Input Type Selection:** The digital inputs can be set to pnp (source) or npn (sink) based on your wiring configuration.
2. **Galvanic Isolation:** The digital inputs are galvanically isolated for added protection.
3. **Nominal Input Voltage:** The nominal input voltage for the digital inputs is 24VDC.
4. **Input Voltage Ranges:**
- For pnp (source): 0-5VDC for Logic ‘0’ and 17-28.8VDC for Logic ‘1’.
- For npn (sink): 17-28.8VDC for Logic ‘0’ and 0-5VDC for Logic ‘1’.
5. **Input Current:** The input current is 6mA@24VDC for inputs #4 to #15 and 8.8mA@24VDC for inputs #0 to #3.
6. **Response Time:** The typical response time for the digital inputs is 10mSec.
7. **High-Speed Inputs:** Specific inputs can function as high-speed counters with a resolution of 32-bit, frequency up to 10kHz, and a minimum pulse width of 40μs.
8. **Wiring Guidelines:**
- Ensure correct polarity and voltage levels.
- Use appropriate wire gauge and insulation.
- Follow proper grounding and isolation practices.
By following these steps and referring to the detailed wiring diagrams in the Unitronics V200-18-E2B Snap-In Input-Output Module user guide, you can successfully wire the digital inputs for your application.
