DGT4: Digital Weight Transmitter / Indicator

Multipurpose weight transmitter for panel mounting on DIN bar.
Ideal as an independent or dependent 4-channel digital junction box, permitting the direct reading and diagnostics of each connected load cell. The wide range of available interfaces, makes it easy to integrate the weighing with any automation system.
CE-M approvable (OIML R-76 / EN 45501).

Main Features:

• Easy to use 5-key waterproof keyboard.
• Highly efficient red LED display with 6 10-mm digits and 6 LEDs for showing active functions.
• Case for mounting on DIN bar or on the wall.
• Calibration, Set-Up parameters, configurable from keyboard or from PC with DINI TOOLS.
• Up to 10.000e or multirange 2 x 3000e @ 0,3 µV/d in CE-M approved version for legal for trade use.
• Up to 800.000 displayable divisions with internal resolution up to 3.000.000 points.
• Up to 8 signal linearization points with DINITOOLS (3 from keypad).
• A/D 24-bit sigma-delta conversion, up to 200 conv./sec. autoselect.
• Connectable with up to 16 analogue load cells with 350 Ohm input resistance.
• Management of a digitally equalised 4-cell weighing system or management of 4 independent weighing systems.
• From 12 Vdc to 24 Vdc power supply.
