DC24V Led Display Controller With AO4-20Ma, Weighing Indicator With
RS232 And DO DI For Ration Packing Scale
Main Features:
- 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.

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