ĐẦU CÂN ANALOG

Main Features：
　EMC design with high anti-jamming capability, suitable for industrial environment.
　24-bit High-precision and high-speed ∑-△A/D conversion module with 1,000,000 internal code used and sampling frequency 400Hz.
　Special 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: 4 Loadcells (350Ω).
　Auto Zero Initial Calibration after Power-on, Auto Zero Tracking, Zero Fine Adjustment and Zero Calibration functions available.
　Data Calibration and Load Calibration functions available.
　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 ‘Fast/Medium/Slow Feeding’ DOs for feeding control. Optional Slow Feeding Modes: Continuous Feeding Mode and Inching Feeding Mode.
　1 Optional and definable analog signal AO[4~20mA] for weight signal output or ‘Fast/Medium /Slow Feeding’ control.
　Optional ‘Fall Value Auto Correction’ function.
　Optional ‘Auto Pause while Deviation Alarming’ function.
　Optional ‘Target Batch & Target Totalized Weight Control’ function [With Target Batch Finished or Target Totalized Weight Finished, the packing process will stop automatically].
　Optional RS232 or RS485 communication ports for linking to IPC/PLC and remote display terminal.
　With the multitasking mode, the weighing&control process will not be interrupted by parameter setting and the other operations.
