MEANING OF "DGTQ" / "DGTQ AN" TERMINAL BOARDS AND BOARDS JUMPERS
• VE 12 / 24 Vdc POWER SUPPLY
1 . +24Vdc +12 / 24 Vdc
2 . GND 0 Vdc (GND)
• CELL LOAD RECEPTORS
CELL1:
6-Pin terminal board C1 – 4-Pin AMP Connector
21. + SIG SIGNAL + 27. - SIG SIGNAL -
22. - SIG SIGNAL - 28. + SIG SIGNAL +
23. + SEN SENSE + 29. - EXC EXCITATION –
24. - SEN SENSE - 30. + EXC EXCITATION +
25. + EXC EXCITATION +
26. - EXC EXCITATION –
!! IMPORTANT !!
If one wants to use 4 wires in the CELL 1 terminal board or in the C1 connector (without using the SENSE signal),
one should short-circuiting - SEN with -EXC and +SEN with +EXC by closing the J1 and J2 jumpers.
CELL2:
C2 – 4-Pin AMP Connector
31. + SIG SIGNAL +
32. - SIG SIGNAL -
33. + EXC EXCITATION +
34. - EXC EXCITATION -
CELL3:
C3 – 4-Pin AMP Connector
39. + SIG SIGNAL +
40. - SIG SIGNAL -
41. + EXC EXCITATION +
42. - EXC EXCITATION -
CELL4:
C4 – 4-Pin AMP Connector
35. + SIG SIGNAL +
36. - SIG SIGNAL -
37. + EXC EXCITATION +
38. - EXC EXCITATION -
• SENSE JUMPER
J1 and J2 = if closed, REFERENCE + and POWER SUPPLY +, REFERENCE – and POWER SUPPLY – for the
channel 1 are jumpered on the board.
• CALIBRATION JUMPER
CAL = if closed, it enables the access to the metrological parameters
• I/O BOOT
Connector for the connection of the ALIBI MEMORY board or for the CLOCK board.
