RGB control panel

Basic characteristics

The RGB control panel is designed for industrial environments. It signals several machine states using color back-lit buttons. Control panels can be equipped with a various number of buttons. Each button is backlit by three primary colors - red, green, blue, which enables 7 color combinations:

• Red
• Green
• Blue
• Orange
• Purple
• Cyan
• White

In addition to lighting up, buttons can also flash. The individual buttons are connected in series. For communication, it uses four data signals.

Properties

• Power Supply: 5 V / 40 mA
• Max. frequency CLK: 1 kHz
• Power/button: max. 70 mA
• Max. buttons in series: 8
• Possibility (number of buttons x number of lines): 1x1, 2x1, 3x1, 4x1, 4x2, 4x4, other on agreement

Examples of use

The RGB control panel is used when you need to display various machine states to operators. For example, during the production of aluminum cans, it is necessary to take samples and measure whether they have the correct dimensions. Each button will be used for measuring one parameter of the cans. On one button the following states can be displayed:

• Unlit button – Quiescent status
• Flashing orange color – Request to measure
• Lighting white color – Measurement of can parameter
• Blinking red color – Measured values are out of set limits
• Lighting blue color – Can is in furnace
• Lighting green color – Request to measure the porosity of can after resurfacing from the furnace

Description of the connection

In most industrial automation cases, 24 V logic is used. Therefore, a converter is needed from 24 V to TTL logic, for example, control panel to PLC. The RGB control panel can be connected to the RGB Link, which allows the connection of up to 2 RGB control panels (8 buttons each).

Test mode

To verify the functionality and the correct wiring of the control panel, there is an integrated test function in the individual LED modules. After connecting the control panel to the power, it has a gradual period of about 250 ms, where lights on each button show the following colors – red, green, blue and white.
