1.4 Documentation
This manual is accompanied by a CD-ROM that primarily contains
information about the installation of the terminal.
Here you will find information on how to interface the terminal with a PC
and PLC.
1.5 Description of the terminal
The model D450 digital weight indicator allows highly accurate and
reliable weighing. This terminal is designed to facilitate dialogue with the
operator through the alphanumeric keypad and graphic display, which, in
addition to being extremely easy to use, has facilities for changing the
shape and size of the display characters to suit various conditions of
use. The D450 terminal provides a wide range functions, which,
combined with the possibilities for expansion, allow for easy interfacing
with external equipment.
Some of the main features of the terminal:
✔facility for connection to a scale with analogue load cells (up to 12 x
350 ohm load cells)
✔facility for connection of up to two scales with analogue cells (up to 12
CPD load cells)
✔two RS232/422/485 serial ports
✔analogue output of 0-10V or 0(4)-20 mA
✔2 inputs and 2 relay outputs
✔110/230 Vac power
✔specific operating modes that can be selected by the operator
✔facility for connection to a tally roll printer, document printer or
labelling machine
✔management of totals files associated with alphanumeric codes
✔quick customisation of keypad and messages
