Function and characteristic
·4-digit LED digital display speed and working mode;
·The LED indicator light displays the working status of internal control, external control, foot switch, etc. in both directions;
·Facial mask key operation;
·It has functions such as start stop, forward and reverse, full speed, speed regulation, and state memory (power-off memory);
·Simple packaging control to achieve the function of repeated transmission of quantitative liquids;
·0.1 when the speed resolution is between 0.1-100 revolutions per minute; At 100-150 revolutions per minute, it is 1;
·Stainless steel shell resistant to acid and alkali, corrosion-resistant;
·High torque output, capable of installing different pump heads to achieve different pump head driver combinations;
·The internal structure adopts a double-layer isolation design, and the circuit board is sprayed with three proof paint technology to achieve dust-proof and moisture-proof effects;
·Strong anti-interference characteristics, wide voltage design, suitable for complex power supply environments;
·External high and low level control for start stop, forward and reverse, simple packaging, optocoupler isolation; External control analog quantity adjusts the speed;
·RS485 communication, supporting MODBUS protocol, convenient for connecting with various control devices;
·It can be controlled by an external foot switch for start and stop or by a time distributor for easy distribution and filling functions;
