Kitoma Indonesia - Menyediakan Digital Indicator Unipulse F805A


LCD Touch Panel Display All-in-One Type Weighing Controller


F805A is a full-fledged device of an all-in-one type that deserves to be called the top-of-the-line loadcell controller.

F805A 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. F805A, 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 loadcell controller.
