Unipulse Weigh Controller F850 is the next step in the evolution of the F-series Weighing Controllers. With its high speed data conversion and versatile configuration, is it any wonder the F850 was given the excellence in product design award by the Ministry of International Trade and Industry (Unipulse Japan).
Standard SI/FII 2-wire high speed (300kbps) bi-directional serial interface allows up to four controllers to communicate with up to 16 peripherals. The E928 (SI/FII to Open DeviceNet) E920 (serial SI/FII to various PLC’s), M350 (printer) LD517 (remote display with accumulator) or E232 (SI/FII to RS232C converter) are easily connected with a total communication distance of over 900 feet (300m).
The Weighing Controller F850 is a versatile controller for Hopper scales, Packing scales and Multi-Ingredients Batching. Add to that, the F850-X1 for In-motion Check-weighing Indicator and F850-X2 for Weigh-in-Motion Truck Axle indicator, and you have a powerful selection for precision weighing and process control accuracy.
