F701-C Weighing Controller with Accumulation Value Display

F701-C is a practical device excellent in cost effectiveness that is compatible with all weighing systems.

F701-C is a general-purpose weighing controller that is compatible with all weighing systems. This is a practical device excellent in cost effectiveness, which is equipped with the final discharge function allowing high-accuracy feeding and discharging weighing control and the weighing sequence function essential to hopper and packing scales. Installable is the interface that can be connected to PLCs or various peripherals such as BCD output, RS-232C and CC-Link.
