The negative‑common configuration means all input channels share a common ground (negative line), simplifying wiring for positive‑logic devices.
Typical Use Cases:
- Monitoring of limit switches, proximity sensors, and pushbuttons
- Reading status signals from PLCs or machine controllers
- Event‑triggered data acquisition or alarm systems
