Digital Load Cell
Amplifier DBB

The digital Load Cell Amplifier in junction box DBB is a combination of cable box and an analog-to-digital converter. The internal high-precision digital amplifier with 24-bit A/D converter converts the output signals of the connected load cells into a stable weight value. The electronic weighing system feeds the load cells and converts, amplifies and filters the analog signal to it then digitized. On the cable box DBB-11 analog load cell 1 can be connected in four-wire technology. On the cable box DBB-14 and DBB-44 up to 4 analog load cells can be connected in parallel in four- wire technology. In DBB -14 every 4 load cells are brought together on one channel. In DBB -44 each cell is evaluated on a separate channel, thus a digital corner adjustment is possible.

Functions

Adjustment is purely digital and, if necessary, also allows separate digital correction of corner errors.
Standard weighing functions are available: Zeroing, taring, totalising, stability detection, automatic zeroing at power-up, and piece counting.

Interfaces and software

Communication with downstream electronics is via a serial bi-directional RS-232 interface or via a 2-wire RS-485 interface. This makes it easy to connect the digital cable box to a computer, PLC or other devices (if an interface is available on the unit). Parameterisation and calibration are carried out via the software supplied.

Construction

The robust aluminium housing is protected against dust and splash water according to protection class IP65. The cables are inserted via brass glands. Connection terminals with screw terminals are fitted in the housing.
