🧩 Functional Overview
The SPR-P06V is tailored to detect and monitor rotating machinery speeds via a magnetic pickup input. It is capable of:
- Start detection: It triggers a contact when rotational speed rises above a threshold.
- Rated speed detection: It asserts when the speed settles within a predefined band.
- Overspeed detection: It triggers when speed exceeds a configured upper limit.
- Acceleration detection: It can monitor when speed increase rate crosses a threshold.
- Fault diagnostics: It senses sensor disconnections and asserts an alarm contact.
The analog output (0–10 V) offers a continual proportional signal representing the current speed, suitable for logging, control systems, or feedback loops. The discrete contacts provide additional binary signals that a controller or alarm system can use.
Accuracy is tightly controlled (±1 % full scale), making it suitable for precision speed monitoring tasks. The response times are rapid (0.2–0.7 s depending on mode) to ensure safe detection of speed transitions.
The device is built to endure harsh environments, tolerating wide temperature ranges and mechanical stress (vibration, impact). Its electromechanical contacts support a modest load (0.5 A), sufficient for status signaling and alarm circuits.
