Peripherals AND AD-8920A

Peripherlas AND AD-8920A

The Peripherlas AND AD-8920A is a versatile and highly readable digital interface designed to extend and enhance the visibility of weighing results from A&D balances and scales. With a large 7-digit vacuum fluorescent display (VFD) and real-time data communication capabilities, it is the ideal solution for environments that require external display readability, remote monitoring, or secondary data output.

This remote display supports both RS-232C and current loop (ACTIVE) communication protocols and features automatic baud rate recognition across a wide range of standard settings. Designed for seamless compatibility with a variety of A&D weighing instruments, the AD-8920A improves operational efficiency in production lines, laboratories, and other professional settings where quick access to measurement results is essential.
