Samkoon EA series touch screen adopts a powerful 32-bit microprocessor, with low power consumption and low temperature rise. Samkoon series touch screens comply with EN55022 and EN55024 standards, comply with FCC, Class A, have strong anti-interference ability, meet the electromagnetic compatibility requirements of industrial environments. It includes internal memory, external system program memory, power circuit module, communication module, display and touch unit, etc.
The characteristics of each module are as follows:
CPU unit
Using 32-bit RISC micro-processing, the operation speed is faster, the power consumption is smaller, and the operation is more stable.
2. Touchpad display unit
Display Control EA and SA series HMIs all use 4-wire high-precision touch pads. These touch pads have the advantages of accurate touch accuracy, durability, and long touch life. The display is LED, with 260,000 true colors.
Communication module
Adopt anti-interference, anti-high voltage, anti-lightning design, enhance the accuracy and reliability of communication, support RS232 / 485/422 communication. EA-035A-T provides a crystal head communication port, EA-035A, EA-070B provides a standard serial communication port, using 9-pin D-type port, which is used to communicate with PLC or other controllers Connect and communicate. When using shielded cable, the communication distance of RS232 should not exceed 15 meters. The communication with the computer provides a USB communication port for downloading the configuration. The speed can reach 10Mbps. The USB interface used is a B-type female port.
Storage unit
Using power-saving FLASH as ROM, the access speed is fast, the flash capacity of all models reaches 128M; the RAM capacity of all EA series is 32M.
5. Power module
Adopt high-precision switching regulated power supply with low power consumption.
6. USB driver
Supports automatic installation, fast USB download speed, strong anti-interference.
7. Quick start
Lights up in 2 seconds; full start in 5 seconds.
8. Data security
New password mechanism, more secure and reliable.
9. Analog module
Support offline simulation; support online simulation.
10. Macro
It adopts C language steps; provides rich function interfaces; supports free-port communication protocols; supports C standard mathematical operation functions; multiple execution methods.
11. Recipe and historical data collection
Support multiple groups of recipes, each group of recipes can set multiple groups of sub-recipes; support the setting of discrete data collection function, the design is more flexible.
12. Custom boot logo
The user can design the HMI boot logo picture by himself and update it into the HMI through the configuration software.
13. Gallery
Provide a large number of rich vector graphics for various industries; support multiple image formats such as BMP, JPG as gallery graphics; provide standard and commonly used vector button frame.
