LZXL-50000P batching controller.

1. An overview of the
The XL-50000 type ingredient controller (hereinafter referred to as the "controller") is a resistance strain sensor as the signal source.
Using the new s-d A/D conversion technology in the 1990s,
And with MCS51 series single chip microcomputer and other large-scale integrated circuits of high precision, high reliability,
Multi-functional intelligent weighing batching controller.
Set high precision weighing display controller and PLC function, which can be used by users for the process and input of the ingredients.
The export function is programmed on site.
Can be widely used in chemical industry, building materials, food, feed and other industries of quantitative packaging or multi-materials automatic batching system.
This controller also has a strong communication function, so that the upper computer can be convenient,
Reliably transmit the various ingredient commands to multiple controllers,
Or read various data from multiple controllers to form a larger batching system.
This controller has the following main functions:
Zero point automatic tracking.
ﾷ panel digital calibration, range, degree value, decimal, overload,
The zero area range and so on can be the panel digital setting.
The recipe table and material list can be programmed by keyboard or upper computer.
Can store 10 kinds of recipes and 10 kinds of material list.
You can choose either incremental or decrement ingredients.
ﾷ continuous ingredients can be set
ﾷ automatic impulse correction, dynamic loading
ﾷ programmable switch with 4 road input
ﾷ programmable switch output with 4 road
ﾷ ingredients, can choose with gross weight, net weight, or differential display
ﾷ can choose manual discharging, the loading operation
ﾷ with WATCH DOG circuit
With RS232C and RS485 serial communication interface, baud rate is optional.
And can set the communication address for multi - machine communication.
ﾷ by panel keyboard, switch input or upper computer communication means for various operations
Equipped with sensor for bridge power supply.
ﾷ has overload, underload, out-of-tolerance, plugging material such as alarm and various working state
