III. Functions and Features
- Frequency to Analog: Linearly converts speed/flow/pulse signals to 4–20 mA for easy integration with PLC/DCS.
- Multi-channel Alarm: 2 relays + 1 transistor, with configurable upper and lower limits, window, fault, and other alarm logic.
- Line Diagnostics: Automatically detects sensor open circuits/short circuits; LED alarm and output trigger in case of fault.
- Startup Shielding: Configurable 1–1000 s startup delay to avoid false alarms upon startup.
- Wide temperature and voltage range: adaptable to harsh working conditions and various power supply scenarios.
IV. Typical Application Scenarios
- Speed/speed/flow/counting monitoring in hazardous areas (e.g., conveyors, pumps, fans).
- Pulse signal isolation and alarm in explosion-proof environments such as chemical, petroleum, and pharmaceutical industries.
- Overspeed/underspeed/locked rotor protection and interlocking control for equipment.
