WBK15, pg. 2 988396 WBK15, 5B Isolated Signal Conditioning Module
Hardware Setup
Configuration
The next figure shows the board layout within a WBK15. Note the channel-number layout for the 5B
modules and the location for plug-in current-sense resistors.
Only current-input type modules require the plug-in resistors.
The plug-in resistors must be removed for all other module types.

Installation of 5B Modules
WARNING WARNING WARNING WARNING
Electric shock hazard! Turn off power to WBK15 and all connected modules and
devices before inserting or removing modules. Failure to do so could lead to injury or
death due to electric shock.
CAUTION CAUTION CAUTION CAUTION
Handle the 5B module carefully while inserting pins into the daughterboard. Do not
over-tighten mounting screw.
The 5B modules plug into a daughterboard (×2) on WBK15’s motherboard. Rubber bumpers on one side
and a tilted daughterboard allow the module to rest at a 5° angle to facilitate insertion and removal. The
adjacent daughterboard has a cut-a-way to allow room for a screwdriver (see figure).
