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.
