Communication: RS485 communication, MODBUS-RTU protocol. It has networking communication function.
● Input: 2-channel switch input (2DI).
Output: 2-channel switch output (2DO), 1-channel analog output (1AO).

summary:

Digital frequency meters are suitable for measuring and displaying electrical parameters of frequency in power grids and automation systems. By setting the magnification through panel buttons, they intuitively display the operating point parameters of the system's primary side. They have the advantages of high accuracy, good stability, and anti vibration, and can directly replace the original pointer instruments.
