Signal Frequency Counter DC 9-15V Module for Industrial Production

Description: -8LED- cost-effective frequency display component of digital tube display. It is mainly used for the display of frequency values of and other equipment, and can also be used for conventional frequency measurement. With PIC16F648A, frequency meter. The frequency reference uses a temperature-compensated voltage crystal oscillator (2.5 ppm ). Adopt unique gate control method and precise time algorithm (non-timed interrupt method). The gate (display refresh) time is 0.01s/0.1s/1.0s optional, and the frequency value is displayed in real time. Single-ended input design, three frequency measurement channels (low channel/high channel/auto channel) are optional. Specification: design, IF value /minus can be separately. It adopts eight-digit 0. high-brightness digital tube display, and the eight-level brightness is adjustable. Invalid zero is automatically blanked, invalid frequency value display filtering is optional, and last digit blanking is optional. The circuit is simple, the structure is reasonable, the double button control, the operation is simple. All settings are automatically saved and directly recalled when power on. Working voltage: put: DC 9V~15V (with polarity protection) Working current: Maximum 160 mA (Test conditions: DC12V ; Red digital tube; Eight-level brightness) Onboard Inteace: (power inteace): .54-2P socket IN (signal input): .54-2P socket ICSP (programming inteace): 2.54 pin Package Includes: 1 Piece Frequency Counter Module Note: 1. Please allow slightly error due to manual measurement. 2. Due to the difference between different monitors, the picture may not reflect the actual color of the item. 3.
