LED Touch-tone Weighing Packaging Calculator for Packing Machine with Ethernet TCP/IP and Modbus TCP
  
          Main Features:
   	- Suitable for Ration Packing Scale. Optional Application Modes: Single-hopper-weighing Mode [Single-scale Mode], Double-hopper-weighing Mode [Double-scale Mode] and Bag-weighing Mode with Auto Bag-releasing or Manual Bag-releasing.
  	- EMC design with high anti-jamming capability, suitable for industrial environment.
  	- 32-bit ARM CPU with 48MHz clock & higher arithmetic speed.
  	- 6+8 Red LED digital tubes for English character and digit display.
  	- 4-key English keypad.
  	- Menu&Shortcut mode operation with key tone.
  	- 24-bit High-precision and high-speed A/D conversion module with 1/1,000,000 internal resolution and sampling frequency 400Hz.
  	- Special anti-vibration digital filtering algorithm for ensuring the weighing stability and accuracy when there is strong vibration on the load receptor, and the rapid response capability when the weight signal changes.
  	- Max. Connection Quantity: 4 Loadcells (350Ω).
  	- Auto Zero Initial Calibration after Power-on, Auto Zero Tracking, Zero Fine Adjustment, Zero Calibration and Load Calibration functions available.
  	- Optional Data Calibration function.
  	- Auto-locking, Key-locking, Key-unlocking, Digital Setting&Calibration and I/O Testing functions available.
  	- 6 Normally open switch inputs [DI] and 8 normally open transistor switch outputs [DO].
  	- Optional ‘High/Medium/Low Speed Feed’ DOs for feeding control. Optional Low-speed Feeding Modes: Continuous Feeding Mode and Inching Feeding Mode.
  	- 1 Optional and definable analog signal AO[4~20mA] for weight signal output or ‘High/Medium/Low Speed Feed’ control.
  	- Optional ‘Fall Value Auto Correction’ function.
  	- Optional ‘Auto Pause for Deviation Alarm’ function.
  	- Optional ‘Target Batch Control’ function [With Target Batch Count or Target Batch Weight finished, the packing process will stop automatically].
  	- 2 Communication ports [RS232&RS485] for connecting Host IPC/PLC and LED Remote Display.
  	- With the multitasking mode, the weighing&control process will not be interrupted by parameter setting and the other operations.
