Applications
Control of centrifuges, ovens, presses, food processing, packaging machines, cleaning systems, washing machines, wood refining machines, compressors, scales, office machines, power converters, heating, cooling, testing and measuring devices with two thermo-couples and/or two resistance thermometers (RTDs) etc. The micro-controller ET-OLED is especially suitable for series production of price sensitive products that require accurate and fast temperature measurements and control, control of frequency converters or servodrives over Modbus, analog or digital outputs.
Advantages
1. Compactness
ET-OLED is suitable for smaller or portable machinery where a compact solution is necessary. The micro-controller ET-OLED (size 86 x 86 x 20 mm) can be a substitute for several PLC modules while still retaining all the required functionality at a fraction of the size.
2. Cost effectiveness
ET-OLED is suitable for smaller or portable machinery where a compact solution is necessary. The ET-OLED (size 86 x 86 x 20 mm) can be a substitute for several PLC modules while still retaining all the required functionality at a fraction of the size.
3. Tailored for your application
The hard- and software of ET-OLED will be tailored according to your requirements. The front panel sticker can be designed according to your wishes. ET-OLED is available also in 96×96 mm DIN enclosure to reduce assembly costs.
