SeaI/O Mounting Kit 
Expanding your I/O count is as simple as adding 
N-Series expansion units to the Base SeaI/O 
module (or other N-series modules). Each N-
Series module includes an expansion and strap kit 
(Item# KT122), which includes a 5” CAT5 
interconnect cable, four metal straps, and four #4-
40 metal screws. The image shows a SeaI/O stack 
configuration using the expansion kit. 
DIN Rail Mounting 
All SeaI/O modules are available with a factory-
installed DIN-rail mounting clip. Alternatively 
DIN-rail mounting clips can be ordered as a field 
upgrade kit (Item# DR104). The bracket with clip 
is easily attached using two included #4-40 
Phillips head machine screws. 
Table/Wall Mounting 
The flush mount bracket kit (Item# KT123) is 
extremely versatile and can be used to mount 
SeaI/O modules from the top, bottom, or back 
edge. Individual modules or a stack of SeaI/O 
modules can be mounted flat to a tabletop, 
underneath a counter, or inside an enclosure. The 
kit can be used to mount SeaI/O modules flat to a 
wall, or along the back edge, similar to DIN-rail 
mounting options. 
Universal Mounting Bracket 
The universal mounting bracket (Item# KT125) 
can be used as a “backpack” to mount power 
supplies and other devices to SeaI/O modules. The 
bracket has holes for both 75mm and 100mm 
VESA mounting options. The universal 
arrangement of slots and holes accept bolt sizes to 
M4 and can be used for virtually any mounting 
configuration.
