D500BC Weighing Controllers

D500BC is a series of compact controllers designed for dynamic weighing applications. Industrially oriented hardware and proven control software allow reliable operation at high accuracy and repeatability, for a small size and at an attractive price.Connectivity to higher level systems is supported with analogue, digital & communication interfaces.

D500BCs can be connected via industrial network to a Host computer for multiweigher applications. The series consists of three versions, namely D500BC-BOS, D500BC-8, D500BC-12 with hardware and software to cover specific applications.All versions meet or exceed EU and OIML R76 recommendations. The unit’s small sized panel mount enclosure may be easily integrated into industrial control cabinets containing also the essential function push buttons and signal lamps.
