High Efficiency Electronic Weighing Indicator With Digital Communication Interface

Product Description

2-Scale TFT-Touch Ration Packing Controller With 2-Weighing-Hopper & 1/2-Bag Electronic Weighing Indicator

     Main Features:

• Suitable for Increment Ration Packing Scale with optional Single-hopper-weighing Mode, Single-bag-weighing Mode, Double-hopper-weighing with one bag-clamping Mode, Double-hopper-weighing with two bag-clampings Mode and Double-bag-weighing Mode.
• EMC design with high anti-jamming capability, suitable for industrial environment.
• Cortex-A8 CPU with 600MHz Clock, 128M RAM and 128M Flash.
• 7”/10.2” Ultralight and ultrathin TFT touch screen with embedded weighing/control module.
• Loadcell Interface

• 2 Loadcell ports. Max. Connection Quantity: 2×8 Loadcells (350Ω).
• 24-bit High-precision and high-speed ∑-△A/D conversion module with 1/1,000,000 internal resolution and sampling frequency 800Hz.
• 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.

• I/O Interface

• 9 Definable normally open switch inputs [DI] and 18 definable 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.
• 2 Definable analog signal AO[0~10V] for weight signal output or ‘High/Medium/Low Speed Feed’ control.

• Digital Communication Interface

• COM1[RS232]&COM2[RS485] for connecting Host IPC/PLC and LED Remote Display.
• COM[RS232] for connecting RS232 Serial Printer.
• USB1 for connecting USB mouse, downloading HMI software from U-disk and copying data to U-disk.

• Software Function

• Manual Screen-locking/Screen-unlocking, Auto Screen-locking, Digital Setting&Calibration and I/O Testing functions available.
• Initial Zero Adjustment after Power-on, Auto Zero Tracking, Zero Fine Adjustment and Zero Calibration functions available.
• Load Calibration and Loss Calibration functions available.
• 10 Recipes for packing control.
• Optional ‘Fall Value Auto Correction’ function.
• Optional ‘Auto Pause for Deviation Alarm’ and ‘Auto Re-feed’ functions.
• Optional ‘Target Batch Control’ function [With Target Batch Count or Target Batch Weight finished, the packing process will stop automatically].
• The Batch Records can be printed automatically.
• Historical Batch Records, Totalizing Reports and Recipes can be queried and printed.
• With the multitasking mode, the weighing&control process will not be interrupted by parameter setting and the other operations.
