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.
