Explanation
Although a small and economical member of the PWI series, the PWI-P panel type indicator/controller finds application in almost all industries due to its versatile programs and functions.
PWI-P can be used on its own in a variety of automatic weighing applications, laboratories, test rigs, as well as tank weighing, filling, discharging, dosing and packaging systems. It also allows various industrial input and output options that make it compatible with PLC devices, computers, etc.
The user selects the appropriate program from the menu and the indicator loads the required parameters into its memory.
