This product is developed based on the first generation Bernard SD model electronic control assembly, further improved and perfected. Compared with the previous generation control assembly, it adds an independent integrated junction box and an effective mechanical padlock. There is a secondary sealing ring at the bottom of its wiring board to further improve the sealing effect. Beautiful and elegant appearance with higher reliability. This product uses an absolute value encoder to detect valve position, with higher valve resolution, and is equipped with an intelligent circuit board to achieve non-invasive debugging and operation without opening the cover. It is designed with a unique three-phase energy consumption braking circuit, which avoids the phenomenon of brake overshoot in reverse braking, and has better braking effect and higher control accuracy. This product can provide non-invasive and intelligent types, with the intelligent type being a dot matrix LCD display with Chinese character menu, which has functions such as parameter configuration, signal query, fault self diagnosis and protection, and data recording. Can be equipped with PROFIBUS-DP, HART, MODBUS, CAN, FF and other buses. 4G, LORA, NB-IOT and other wireless communication controlled by cloud platform can also be selected to achieve IoT control.
