MEANING OF "DGT4 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:
18. SIG+ SIGNAL +
19. SIG- SIGNAL -
20. SEN+ SENSE +
21. SEN- SENSE -
22. EXC+ EXCITATION +
23. 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:
24. SIG+ SIGNAL +
25. SIG- SIGNAL -
26. EXC+ EXCITATION +
27. EXC- EXCITATION -
CELL3:
28. SIG+ SIGNAL +
29. SIG- SIGNAL -
30. EXC+ EXCITATION +
31. EXC- EXCITATION -
CELL4:
32. SIG+ SIGNAL +
33. SIG- SIGNAL -
34. EXC+ EXCITATION +
35. EXC- EXCITATION -
