概述 Overview

数字屏装显示表适用于电力电网、自动化控制系统，主要测量电网中的电流，按照其附加功能划分，我们拥有X、K 系列数显仪表。

X 系列智能数显仪表，是通过直接交流采样，并采用真有效值算法测量电流，并由数码管(LED) 直接显示的数字式电量仪表。

K 系列智能仪表则是在X 系列基础上可选配1-3 路模拟量变送输出(4-20mA 等) 及一路RS-485 通信接口输出( 采用Modbus-RTU 协议)，1-4 路开关量输入

测量功能( 实现“遥信”) 和1~2 路路继电器报警输出功能( 实现“遥 控”)，以方便组网的显示仪表，并且可以直接三排数码显示或者单排数码管显示。

从测量的电力网络分，还可以分为单相电流表和三相电流表，单相电流表为单排数码显示。三相电流表为三排数码显示。

The digital screen mounted display meter is suitable for power grids and automation control systems, mainly measuring the current in the grid. According to its additional functions, we have X and K series digital display instruments.

The X series intelligent digital display instrument is a digital power meter that measures current through direct AC sampling and uses the true effective value algorithm, and is directly displayed by a digital tube (LED).

The K series intelligent instrument is an optional display instrument based on the X series, which can be equipped with 1-3 analog transmission outputs (4-20mA, etc.) and one RS-485 communication interface output (using Modbus RTU protocol), 1-4 switch input measurement functions (realizing "remote signaling"), and 1-2 relay alarm output functions (realizing "remote control"), to facilitate networking, and can directly display three rows of digital display or single row digital tube display.

From the measured power network, it can also be divided into single-phase ammeters and three-phase ammeters, with single-phase ammeters displaying a single row of digital signals. The three-phase ammeter has three rows of digital display.
