About This Product
■Summary
The TDP-3941 is a digital panel type universal revolution/speed meter with a compact DIN size design of 96 x 48 mm and equipped with a high-speed F/V function with 1 pulse response as standard. It has various functions such as a wide measurement range from 0.1Hz to 30kHz, support for various signal inputs, independent isolation between input and output power supplies, and AC-free power supply.
■Wide measurement range from low speed to high speed
The Periomatic TM method allows wide range measurement of input frequencies from 0.1Hz to 30kHz. The Periomatic TM method is a frequency measurement technology that is said to be the ultimate ideal, and compared to the conventional periodic calculation method, it has higher accuracy, stability in low-speed measurements, and better responsiveness to speed fluctuations. The Periomatic TM method was started by Coco Research Co., Ltd.
■Latematic method TM and averaging function
Input frequencies from 0.1 Hz to 30kHz can be scaled and displayed in the range from 0.00001 to 99,9999. It is also equipped with averaging functions such as frequency division function (1~255) and moving average function (1~32) to cope with jerky rotation.
■Incoming/outgoing car power supply isolation
The input terminal, output terminal, and power supply are each independently isolated (electrically isolated) for exchange of names.
■High-speed analog output standard equipment
As a digital panel type tachometer, it comes standard with an analog output (16bit D/A converter adopted) with the fastest response time (13μs or less). Reverse measurement (10V output) is also possible by inputting A/B phase signals, UP/DOWN signals, etc.
■Equipped with 2 high-speed comparator outputs as standard
Equipped as standard with 2 comparator outputs with response speed of 0.5ms or less. Adopts a non-contact photomos relay for both AC/DC and provides output without chattering problems.
■Supports various input signals
Compatible with a variety of signals, including NPN open collector and line driver support, TTL, and AC signal zero-cross detection, and supports a variety of input signals such as rotary encoders, various pulse output type speed sensors, electromagnetic pickups, motor drivers, etc. You can enter it directly.
■AC free power supply
AC free power supply supports up to AC100~240V (AC85~264V).
