Explanation:
Though a small-size and cost-effective member of the PWI series, the PWI-P panel type indicator/controller finds application virtually in all industries thanks to its versatile programs and functions.
PWI-P can be used alone in various automatic weighing applications, laboratories, test devices, and tank weighing, filling, discharging, batching and bagging systems. Furthermore, it allows for various industrial input and output options which make it possible to communicate with PLCs, computers, etc.
The user selects the related program from the menu and the indicator uploads the necessary parameters to its memory.
