-
The DVP12SA is recognized for reliability, high-speed operation, and flexibility in small-to-medium industrial automation projects, making it perfect for businesses looking to upgrade their automation infrastructure.
The Delta DVP12SA and DVP12SA2 are both slim PLCs, but the DVP12SA2 is a second-generation model with notable enhancements over the original DVP12SA. Below is a comparison highlighting the main differences:
| Feature | DVP12SA | DVP12SA2 |
|---|---|---|
| Program Capacity | 8k steps | 16k steps |
| Max. I/O Extension | 236 points | 492 points |
| High-Speed Pulse Output | 2 points: 50kHz & 10kHz | 2 points: 100kHz & 10kHz |
| Data Register | 5k words | 10k words |
| CPU | 32-bit | 32-bit |
| Communication Ports | 1 RS-232, 1 RS-485 | 1 RS-232, 2 RS-485 |
| Execution Speed | 0.35 μs | 0.35 μs |
| RTC Feature | External battery | Built-in; runs 15 days w/o power |
| Output Methods | Relay or Transistor | Relay or Transistor |
| Module Compatibility | DVP-S extension modules | DVP-S series modules |
Main Takeaways
-
DVP12SA2 offers double the program capacity and I/O extension, plus more advanced pulse output and built-in RTC functions not available in the DVP12SA.
-
DVP12SA2 is more suitable for increasingly complex automation systems, while the basic DVP12SA fits simpler or legacy uses.
