Graphic display/touch panel type all-in-one type weighing indicator

Product outline

F805AT adopts a color LCD touch panel which enables simple and comfortable operation by greatly enhancing the visibility of weight display, various setting values display and status display. It provides high-speed A/D conversion and digital processing capability at an operating speed of 1000 times/sec There are substantial interfaces that allow direct connection to major PLCs including OMRON DeviceNet and MITSUBISHI CC-Link. F805AT, which was developed specifically for weighing systems, is a full-fledged device of an all-in-one type that deserves to be called the top-of-the-line Weighing indicator.

Setting section
Setting method – Setting by touch panel operation

(Depends on usage conditions and storing environment, but memory can be kept for approx. 7 years or more.)
Setting value protection Setting operation can be locked to prevent unauthorized modifications of default values and calibration by malfunction (LOCK)
