DL21 Numerical Diplay Panel

DL21 numerical display panels are destined to display numerical values read out from a connected device or assigned value through the programming interface in the selected colour by the user. Considering the luminosity of display segments and the housing design they are destined for indoor applications. These display panels find application to display numerical quantities in office rooms, production halls in management points as information about production parameters, machine state, device working state, etc. The displayed value on the display can originate from external devices operating in MODBUS standard, and at the same time it is possible to configure the display to work as “Master” or “Slave”. Moreover, the display enables to connect 10 slave devices to it, and this make possible to fulfill the task of a local point of data acquisition. All data read out from slave devices can be read out through the RS-485 interface. The value can be displayed in the chosen colour (green, red or orange) by the user or the display colour can be changed depending on the indicated value. Moreover, the minimal and maximal indicated value is defined by the user. DL21 display panels are equipped with two RS-485 communication interfaces operating in the MODBUS RTU standard. One of the interfaces is destined to connect slave devices, whereas the second interface is destined to configure the display or to introduce the displayed value ( the display fulfills the part slave in the MODBUS network). The basic display execution includes three digits and the place destined to locate the unit. It is possible to make a display composed of DL21 digits in the configuration defined by the user.

Description

The DL21 advantage is its three-color display (green, red and orange) on which the color of displayed parameter can be freely programmed and can change depending on values set by the user.
This display panel finds a large application in office rooms, public utilities (e.g. information about temperature, humidity), production halls – information about production machine state, number of made pieces, energy consumption) etc.
The DL21 display has two RS-485 communication interfaces in MODBUS standard destined to:
– connect external devices,
– configure the display or introduce displayed values.
The display enables the connection of 10 external devices and to apply it as a local point of data acquisition. It can co-operate with external devices as “master” or “slave”.
The basic execution of the display includes 3 digits and a space destined to place the unit. It is also possible to execute the display in the configuration definite by the user.
