HI 3030 general-purpose weight controller is designed for use in tank farms, level weighing, batching, filling, dispensing and check weighing applications. It can control up to four independent scales at one time and acts as a bridge to a PLC since one port works with all four channels over a standard DeviceNet network or optional ControlNet. Controller incorporates 12 set points with independent dead bands. Self-adjusting preacts are assignable to four on-board relays or external third party I/O.
