Setup
Reference Note
For a quick set up involving connecting a WBK40 or a WBK41 to a WaveBook/516E or to a
WBK25, refer to the
WBK40 & WBK41 Installation Guide (p/n 1066-0901). For convenience,
a copy has been placed after the specifications section of this document.
Hardware Setup, for WBK40 and WBK41
WARNING
Electrical Shock Hazard! To avoid possible injury and equipment damage, turn off power to
devices and connected equipment prior to setup.
Connecting to the Channel Input Side
WBK40 and WBK41 each have a row of 14 mini-TC connectors. These are for connecting thermocouples to
channels 1 through 7 and to channels 9 through 15. Channels 0 and 8 have no mini-TC connectors, as these two
channels are used for cold-junction compensation (CJC). The connection information regarding thermocouples is
included in the upcoming sub-sections,
Thermocouple Connections (page 6) and Open Thermocouple Detection
(page 7).
In addition to thermocouple connections, the WBK41 can accept signal lines for the following:
16 Digital I/O Lines (via front panel screw-terminal blocks) •
•
•
•
•
24 Digital I/O Lines (via a rear panel 37-pin connector, P2)
4 Counter Inputs (via front panel screw-terminal blocks)
2 Timer Outputs (via front panel screw-terminal blocks)
4 Channel, 16-bit, 100 kHz Analog Output (via front panel screw-terminal blocks;
but only when a factory-installed DBK46 option is in place)

Note 1: Each DBK84 module requires a unique address setting as explained on page 13.
144 Digital I/O
(via 3 DBK21 Cards in a DBK10 Chassis)
14 Thermocouples can be connected to
each DBK84 and to the WBK41 (or WBK40).
For WBK41: Digital I/O, Counter Input
(CNTR), Timer Output (TMR), and Analog
Output (DACS) lines can be connected to
the associated terminal block screw
connectors. (See following photo.)
