WBK41
Multi-Function I/O Module
14 Thermocouple channels via Mini-T/C Connectors
40 Digital I/O Lines
4 Counter Inputs
2 Timer Outputs
(Optional) 4 Analog Channel Outputs
The WBK4 attaches to the parallel expansion port on the
WaveBook/516E or WBK25 and provides 14 thermocouple inputs, 40
digital I/O lines, 4 counter inputs, and 2 timer outputs. The WBK41
can also be supplied with an internal, 4-channel, 16-bit,
100-kHz analog output option.
The built-in TC channels on the WBK41 are accessed via mini-TC
connectors on the front panel. The counter/timer functions and 16
bits of digital I/O are accessed via removable front panel screw-
terminal connectors. Additional digital I/O and expansion connectors
are located at the rear of the WBK41.
The WBK41 can be easily expanded beyond its built-in channel
capacity. A maximum WBK41 system can include up to 224 TC input
channels, 272 digital I/O channels, 4 analog output channels,
4 counter input channels and 2 timer output channels.
WBK61 and WBK62
WBK61: High-Voltage Adapter with 200:1 Voltage Divider
(1 channel)
WBK62: High-Voltage Adapter with 20:1 Voltage Divider
(1 channel)
WBK61 and WBK62 are single-channel high-voltage adapters that
can be used with the WaveBook or WBK10A expansion modules.
In addition, WBK61 and WBK62 can be used in conjunction with
WBK11A, WBK12A, and WBK13A option cards.
WBK61 and WBK62 include safety-style banana-jacks for the high
and low inputs, and 60-inch (152 cm) cables with probe tips and
alligator clips for easy input connection.
WaveBook Fan
The internal components of WaveBook/512A, /516, /516A, and /516E are air-cooled. Cooling
to ambient occurs as long as the surrounding environment is cooler than the unit. When the
unit becomes too warm for ambient cooling, a temperature sensor signals the fan to run.
Fan speed varies according to the WaveBook’s internal temperature. In cooler temperatures
the fan operates at lower speeds, thus reducing audible noise.
To allow for sufficient cooling, it is important to keep the fan and vents free of obstruction.
Note: The partial blocking of vents by fastener panels, when the units are stacked, does not
jeopardize unit cooling.
