Unipulse F701-C weighing controller with accumulation function
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.
