Measurement Computing DBK Part 2 - Manual (Page 172)

CE Compliance
If your data acquisition system needs to comply with CE standards, the DBK85 must be connected to the
LogBook or Daq device by a CA-143-x cable. In addition, the CE compliant operating conditions must be
met as specified on the DBK85 module’s Declaration of Conformity card, which is shipped with the
module.
Reference Notes: If your data acquisition system needs to comply with CE standards,
refer to the following:
o
the DBK85’s Declaration of Conformity
o
the CE Compliance section of Signal Management chapter of this manual
Connecting the DBK85 to Signals and to the Primary Data Acquisition Device
You can connect the DBK85 module to your primary data acquisition device and to its signal inputs after
you have completed the following:
• set the DBK85 module’s address
• configured the primary data acquisition device, if applicable
You can connect up to 16 signal lines to one DBK85, i.e., one per BNC. These inputs accept voltages up
to
±10 VDC.
Connect the DBK85 module as follows. Note that if your system needs to be CE Compliant, be sure to
read the preceding CE Compliance section prior to connecting the DBK85.
1.
Connect each signal input line’s BNC connector to a mating connector on the module. Overlays for
CH0 to CH15 identify the associated BNC. Remember, signal input is limited to ±10 VDC.
Tip: Label each signal input line with its associated channel information.
2.
For a single DBK85 module, connect one end of the P1 cable to the module’s male DB37 output
connector.
For DaqBook applications - use a CA-37-x cable.*
•
•
•
For DaqBoard/2000 Series or /2000c Series boards - use a CA-37-x with a DBK200 Series
adapter.*
For DaqBoard [ISA type] boards - use a CA-131-x cable.*
* CA-37-x and CA-131-x cables do not meet CE compliance requirements. Refer to the
preceding CE section if CE compliance must be met.
3.
Connect the free end of the cable to the P1 port of the LogBook or Daq device. For multiple DBK85
modules, use a CA-37-x (or CA-131-x) cable to daisy-chain several modules or an expansion
module. For example, three DBK85s could be connected to a LogBook or a Daq device via a CA-
37-3 cable.
Note: For longer cable runs you can use a CA-113 cable to add 6 ft of length.
