AMC72-DV DC voltmeter is often used in DC motor drive circuits, battery charging circuits, battery testing, etc. Using direct access, you can choose digital tube or liquid crystal display, and the opening size is 67*67mm. It can be equipped with 4-20mA analog output, 1 relay alarm output, and 2 switch input/output. It can not only be used for local display, but also can be connected with industrial control equipment to form a measurement and control system.
