Coco TDP-3941 Tycadometer With 1-Pulse Response And High-Speed F/V Function

Manufacturer: Coco Research Co., Ltd
Model: TDP-3941

Features

Tycadometer TDP-3941 digital panel meter with 1-pulse response, high-speed F/V function, wide 0.1Hz–30kHz range, dual comparator output, and isolated design for precise industrial speed and frequency measurement.

The Tycadometer TDP-3941 is designed with a 1-pulse response and high-speed F/V function, and accurate frequency measurement is achieved with fast and stable signal processing. As a result, precise and reliable performance is ensured across industrial applications.

Moreover, a compact 48×96 mm DIN-sized design is adopted, and integration into standard panels is simplified. In addition, a wide measurement range from 0.1 Hz to 30 kHz is supported, so compatibility with various signal inputs is enabled.

Furthermore, a high-speed comparator output with 2 channels is provided as standard, and efficient monitoring and control are achieved. As a result, system functionality is expanded while real-time response is maintained.

In addition, independent isolation is provided between input, output, and power supply, and therefore noise interference is reduced while system stability is improved. An AC-free power supply is also supported, so flexible installation is ensured in different environments.

Overall, the Tycadometer TDP-3941 combines fast response, precise measurement, and reliable design, so it supports efficient and accurate speed and frequency monitoring in industrial systems.
