The input size changes to four words. The revision number for the
series B 1769-IF4 module is two. With this setting, you may leave the
electronic keying to Exact Match. It is not recommended to disable
keying, but if you are not sure of the exact revision of your module,
selecting Compatible Module allows your system to operate, while still
requiring a 1769-IF4 module in slot 1.
The series B 1769-IF4 module differs from the series A module only in
that it allows external 24V dc power. The external power connection
allows you to draw 24V dc power for the module from your external
source, should your 1769 power supply not provide enough 24V dc
power for your particular set of 1769 I/O modules.
