The IND9D56 checkweighing controller provides a robust and reliable interface to conveyor scales for in-motion weighing. Items can be weighed while crossing an analog load cell-based conveyor at speeds up to 1000 meters/minute. Data from bar code scanners, RFID readers, or dimensioning equipment can be integrated with the IND9D56 to provide a complete transaction record. A target can be recalled and weights compared against target values to trigger an output or identify in the transaction record out of tolerance items. Optional Ethernet and PLC connectivity provides flexibility for interface to other control or data analysis equipment.
