Power Supply Connector
 
The Power Supply connector (base modules only) is a two-position removable terminal 
block located on the top of the unit. Terminal spacing is 3.5 mm. The terminal block 
accepts solid and stranded wires from 28 AWG to 16 AWG.   Please check polarity 
marking in Figure 8.
 
Refer to the following section for information on Power Supply Requirements. 
Expansion modules receive power from the base module via the local bus connector. 
Local Bus Connectors
 
Local Bus connectors are included on all base and expansion modules. These connectors 
are dual row, 14 pin (2 mm spacing) connectors. Base modules have only a female 
connector. Expansion modules have male connectors on one side and female connectors 
on the other. Modules are plugged together to supply power and facilitate communication 
between modules. 
When adding an Expansion module to a Base module the male connector on the expansion 
module plugs into the female connector on the base module. The second expansion module plugs 
into the first, and so on, up to a maximum of six expansion modules.
