Belt Scale Digital Weighing Instrument Controller With Profibus-DP/Ethernet
   
  Main Features:
   	- Suitable for Ration Belt Weighfeeder with Ration Flow Feeding & Ration Weight Batch Control.
  	- EMC design with high anti-jamming capability, suitable for industrial environment.
  	- 32-bit ARM CPU with 72MHz clock & high arithmetic speed.
  	- 128×64 LCD display screen with 7 background colors for English display.
  	- 16-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.
  	- Broad-range speed pulse input circuit.
  	- 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: 8 Loadcells (350Ω).
  	- Auto-locking, Key-locking, Key-unlocking, Digital Setting&Calibration and I/O Testing functions available.
  	- Auto Zero Tracking, Speed Calibration and Belt Length Calibration functions available.
  	- One optional ‘Flow Setpoint’ analog signal input [AI: 4~20mA].
  	- Max.3 definable ‘Flow/Control Current /…’ analog signal outputs [AO: 4~20mA].
  	- Quick and steady PID ration feeding control.
  	- 3 Definable normally open switch inputs [DI] and 4 definable normally open relay switch outputs [DO].
  	- The feeder and belt weigher can be started and stopped by DI&DO signal.
  	- 1 ‘Totalized Weight High-speed Pulse’ output [PO].
  	- 2 Optional communication ports for connecting IPC/PLC, LED Remote Display, Serial Printer and Wireless Module.
  	- Weight Records per shift/day/month of a year can be queried and printed.
  	- With the multitasking mode, the weighing&control process will not be interrupted by parameter setting and the other operations.

  Keypad Operation
  If there is not any keypad operation in one minute and it’s not in the processes of ‘F2 Calibration’ & ‘F6 Factory Adj.’, the controller will return to ‘Main Display Interface’ automatically.
