- Quick and steady PID ration feeding control.
- 3 Definable normally open switch inputs [DI] and 4 definable normally open relay switch outputs [DO].
- The feeder and belt weigher can be started and stopped by DI&DO signal.
- 1 ‘Totalized Weight High-speed Pulse’ output [PO].
- 2 Optional communication ports for connecting IPC/PLC, LED Remote Display, Serial Printer and Wireless Module.
- Weight Records per shift/day/month of a year can be queried and printed.
- With the multitasking mode, the weighing&control process will not be interrupted by parameter setting and the other operations.
