Features of GGD-33A GGD-33E Load cell controller

It can control the batching of four materials, and each material has the function of fast and slow feeding control.

Automatic drop correction.

Set the working batch and automatically recycle ingredients as required.

The formula setting is flexible and can meet the batching requirements of different levels.

Eight recipes can be stored at the same time.

The main and auxiliary double six digit digital display screens are used for the dynamic display of the weight or error value of a single material in the batching process.

Sixteen touch sensitive and sound keys, including ten numeric keys, are convenient to operate.

Comprehensive plate digital adjustment and parameter setting, without any hardware setting, and password protection is provided for important parameters.

Strong anti-interference ability and dual reliability design of watchdog circuit to ensure accurate operation.

Operation status and data power-off protection to ensure safe control.

High resolution and high stability analog-to-digital conversion is adopted, and the display degree can reach 65000 words at most.

Perpetual calendar date and time function not affected by power failure.

The non-polar non-contact electronic switching output is adopted to ensure the long-life operation of the whole machine.

It has a printing interface, which can be connected to Epson LQ-300 or compatible printer, print the general formula table in Chinese, run the formula and each batching result.

With RS-232 serial communication interface, it can accept formula management and provide data and operation status.
