Loss-in-weight Electronic Weighing Indicator For Ration Packing Scale
Suitable for Loss-in-weight Ration Packing Scale with Auto Bag-releasing or Manual Bag-releasing and Loss-in-weight Bulk Material Ration Feeding Scale.
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 occuracy 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.
