Overview
The DBK33 provides added power (±15 VDC and +5 VDC) via P1 in configurations where the expansion
cards require more power than available from a LogBook, DaqBook, DaqBoard, or /2000 Series device or
other power source. The card is compatible with all analog DBK cards and typically can support up to 12
DBK cards.
Note: If +5 V is not needed by the DBKs in use, you can use the DBK32A in place of the DBK33.

  • Page 2 If configured such, damage to the 8254 timer chip will result. Using a DBK33 requires you to entirely remove the shunt jumpers from header JP1 inside the DaqBook/100 Series & /200 Series device or DaqBoard [ISA type], as shown in the figure. DaqBooks/100 Series &...
  • Page 3 DBK33’s DB37 P1 connector interfaces with the analog DBK in one of two ways: a) Via a backplane, such as in the case of installing the DBK33 in a DBK41. For products with P1 backplanes, if you will be installing a DBK33 internally, you must have the correct configuration of a backplane jumper(s) to disconnect the device’s +5 VDC from the backplane.
  • Page 4 DBK33’s J1B Terminal Block Terminal block J1B has one positive (+) and one negative (-) screw terminal. The terminal block power connection is available for use as an alternative to using a DIN5 connector. As indicated in the block diagram on page 1 of this section, all three connectors are in parallel, i.e., the two DIN5 connectors and the JB1 terminal block.
