FFU field intelligent control oled module

Field intelligent control module to microcontroller core processors to achieve control. An intelligent module controls one FFU. Field intelligent control module is divided into voltage regulator module and inverter module, two kinds of intelligent control module enables the following control functions:
1) intelligent module has a strong opening, with optional HART (pluggable) site control can be achieved: by reserving the RS485 interface enables remote centralized control and fault diagnosis and setting: With the optional The remote control module (pluggable) can achieve remote control. 20x2 lcd display
2) through removable handheld enables start and stop FFU and accurate variable speed FFU outlet velocity values ​​can be displayed.
3) The intelligent module enables FFU with energy-saving features.
4) with overload and short-circuit protection functions: overload, prompting alarm unit alarm; short, prompting alarm unit FFU alarm and automatically cut off the power.
Wired control

Wired control mode control mode is optional, it is set aside by field intelligence module RS485 interfaces. In order to meet the needs of different users, we use the control panel and touch screen control modes, the control panel is simple, but the display is not intuitive, and achieve limited functionality; touch screen cost, easy operation, display a rich and powerful.
Touch screen control method consists of the following three components: 1) the central control unit; 2) human-machine interface unit; 3) alarm control unit. graphic lcd 128x64
