Built-in type weighing indicator for CC-Link

Product Outline

F156 is a weighing controller that can be directly connected to Mitsubishi Electric’s general-purpose sequencer. It allows the weighing system construction time to be reduced with serviceability improved. Equipped with the weighing sequence function, which allows direct control of feeding and discharging gates only by entering the target weight value, F156 of compact design is ideal for use integrated into a control panel, etc. Its integration into equipment and installation of DIN rail are also supported.
