TFT Touch Load Cell Indicator Weighing Controller 24 Bit High Precision

Packing Scales Weight Control, Load Cell Weighing Controller

            Main Features:

² Suitable for Ration Packing Scale with optional Hopper-weighing Mode, Bag-weighing Mode and Loss-in-weight Mode.

² EMC design with high anti-jamming capability, suitable for industrial environment.

² Cortex-A8 CPU with 600MHz Clock, 128M RAM and 128M Flash.

² 7”/10.2” Ultralight and ultrathin TFT touch screen with embedded weighing/control module.

² Loadcell Interface

l Max. Connection Quantity: 16 Loadcells (350Ω).

l 24-bit High-precision and high-speed ∑-A/D conversion module with 1/1,000,000 internal resolution and samplingfrequency 800Hz.

l Special anti-vibration digital filtering algorithm for ensuring the weighing stability and accuracy when there is strongvibration on the load receptor, and the rapid response capability when the weight signal changes.

² I/O Interface

l 9 Definable normally open switch inputs [DI] and 18 definable normally open transistor switch outputs [DO].

l Optional ‘High/Medium/Low Speed Feed’ DOs for feeding control. Optional Low-speed Feeding Modes: Continuous Feeding Mode and Inching Feeding Mode.

l 2 Definable analog signal AOs[0~10V] for weight signal output or ‘High/Medium/Low Speed Feed’ control.

² Digital Communication Interface
