Product Description

Product Details:
 

SM8804CD weighing controller is a class of weighing control instrument specially developed for dual scale incremental method automatic quantitative packaging scale. This product is a traditional classic dual scale packaging control instrument, which can be widely used in grain, seed, feed, chemical and other industries requiring quantitative packaging equipment.

Product features:

1.Dual scales feeding control, working modes such as hopper/no hopper/bulk material totalization;

2.Feeding control, bag tapping, dunnage bag, discharging vibration;

3.Batch number setting and total amount of shipment setting function;

4.Dual serial port communication function, two sets of independent parameters, can be the same;

5.Communication and connection to printer at the same time;

6.Serial connection to the GM8897 touch screen;

7.Flow statistics and display function (bulk material totalization mode);

8.Simulation function, which is convenient for on-site equipment debugging;

9.Quick modification of recipe parameters during operation;

10.Software update through computer;

11.Rich IO ports, including 12 switch inputs and 16 switch outputs, in addition to meeting its own packaging needs, some can be reserved for backup, and through the switch definition to define the port, which can solve the situation of some port abnormalities, burned out, not working;

12.10 groups of formula storage function, convenient for customers to store and switch the packaging parameters of different kinds of materials with different specifications;

13.two 24-bit high-precision AD data acquisition module, a single meter can realize the packaging process of double scales, the meter has a logic interlock function, simplify the circuit design of the electronic control cabinet, reduce the failure points;

14.The working mode is divided into: with measuring hopper, without measuring hopper, bulk, the user used to be able to configure this parameter according to their own process requirements or the mechanical structure of the scale to meet the needs of adaptive applications, such as bulk scales, then select the bulk mode can be;

15.automatic three-speed control, and large, medium and small can be used in combination or independent output, which can simplify the customer's electrical diagram design and to achieve a variety of control modes, and can be material speed to improve the speed and accuracy of the packaging (later upgraded to four-speed);

16.Feeding control function, through the setting of the upper and lower material level, can realize the automatic replenishment function of the feeding equipment, so as to ensure that the material in the feeding hopper is balanced and maintained at a certain warehouse pressure, to improve the accuracy of the packaging (later upgraded to three material level control);
