MEANING OF DGTP / DGTP AN / DGTP PB TERMINAL BOARDS AND MOTHER BOARD
JUMPERS
• VE 12 / 24 Vdc POWER SUPPLY
1 . +24Vdc +12 / 24 Vdc
2 . GND 0 Vdc (GND)
• CELL LOAD RECEPTORS
CELL1:
17. SIG+ SIGNAL + CELL1 – 4-Pin AMP Connector
18. SIG- SIGNAL - 1. EXC+ EXCITATION +
19. SEN+ SENSE + 2. EXC- EXCITATION -
20. SEN- SENSE - 3. SIG+ SIGNAL +
21. EXC+ EXCITATION + 4. SIG- SIGNAL -
22. EXC- EXCITATION -
!! IMPORTANT !!
If one wants to use 4 wires in the CELL 1 terminal board (without using the SENSE signal), one should short-
circuiting - SEN with -EXC and +SEN with +EXC.
CELL2:
CELL2 – 4-Pin AMP Connector
1. + EXC EXCITATION +
2. - EXC EXCITATION -
3. + SIG SIGNAL +
4. - SIG SIGNAL -
CELL3:
CELL3 – 4-Pin AMP Connector
1. + EXC EXCITATION +
2. - EXC EXCITATION -
3. + SIG SIGNAL +
4. - SIG SIGNAL -
CELL4:

1. + EXC EXCITATION +
2. - EXC EXCITATION -
3. + SIG SIGNAL +
4. - SIG SIGNAL -
• CALIBRATION JUMPER
J1 = if closed, it enables the access to the metrological parameters
• I/O BOOT
Connector for the connection of the ALIBI MEMORY board.
