Abstract
Analysis of the functions of the microprocessor of the terminal, the peculiarities of the four analog current inputs and four analog input voltage devices 7SJ624 and 7SJ64. Outlined the features of digital inputs and outputs serial interfaces. Considered a separate service interface to record data with a remote control center via a personal computer and a serial system interface for various protocols and data transfer to a central monitoring and control system.

Influence of number of radial slits of ferromagnetic screen on linear induction-dynamic transducer attributes
Proposed the concept of a linear induction-dynamic transducer (LIDT) in which ferromagnetic screen (FS) is provided with radial slits. It was found that an increase in the number of radial slits decreases the induced cur...
