QDI-10K Electronics 160 Times / Second RS232 Weighing Instrument

Product Description

CONHON Electronics QDI-10K Weighing Display Controller Industrial Weighing Instrument Packaging Meter

product description:

1. QDI-10K weighing controller is a multifunctional control instrument, 6-digit 0.8 ”LED display, aluminum alloy housing.
2. It can be used as a three-setting value control instrument and can be set as a stable automatic selection nickname. Can also be used as a packaging control instrument. Can also be used as a high-speed peak hold meter.
3. Equipped with RS232 communication interface, can be connected to large screen display or serial printer.
4. Equipped with RS485 communication interface and ModbusRTU communication protocol, which can be combined into a distributed control system.
5. Bi-directional measurement, high-speed A / D (160 times / second).
6, four relay output contacts, contact withstand voltage AC200V / 1A.
7. Two switch / button inputs. It can be used as trigger accumulation mode and used as automatic accumulation scale.
8. The keyboard can be locked to prevent misuse during use.
9. Equipped with 4-20mA current output, digital adjustment and easy operation.

Action process of various modes:

1. There is a bag clamping method without hopper: start signal, start bag clamping, tare and add material after delaying time t1 (fast adding => slow adding), slow feeding is closed, delay t2, automatically accumulate to determine whether it is out of tolerance. Poor, alarm t5 time "ALrn is displayed" Finally, the bag is loosened and stopped. (Single cycle work)

2. There is a hopper and a bag clamping method:

The first start signal determines whether there is material in the hopper.

With material: start bag clamping, unloading (the weight in the hopper is greater than the fast adding value) No material: start adding the material (fast adding => slow adding)
Slow feeding closing delay t2 time, automatically accumulate to judge whether it is out of tolerance, wait for the start signal
The weight is less than the zero zone, and then maintain the feeding time t3, close the feeding, loose the bag and delay the time t4, peel and then enter the automatic feeding (fast feeding => slow feeding); (in the feeding process, you can clamp the bag); Delay time t2 when feeding is closed, it will automatically judge whether it is out of tolerance. If it is out of tolerance, alarm t5 will show "ALrn" and wait for the start signal to clamp the bag, unload and cycle. }

3. There is no bag clamping method with hopper:

start signal to determine whether there is material in the hopper
With material: start to discharge (weight in hopper is greater than fast replenishment) No material: {start to replenish (fast increase => slow increase), feed closing delay t2 time, automatically determine whether it is out of tolerance, if it is out of range, alarm t5 time is followed Automatic unloading, the weight is less than the zero zone, and then maintain the unloading t3 time, close the unloading delay t4 time, peel the skin, and then enter the feeding control, and cycle work. }

4. Single mode with hopper measurement and bag clamping:

start signal to determine whether there is material in the hopper
With material: start discharging (weight in the hopper is larger than fast adding value) No material: start adding material (fast adding => slow adding), delay time for feeding closing t2, automatic accumulation
Determine if it is out of tolerance, if it is out of tolerance, alarm t5 time, wait for the start signal, clamp the bag, unload and unload, the weight is less than zero zone, then maintain the unloading t3 time, close the unloading delay t4 time, peel and stop. (Single cycle work)
