DIN Rail Mounting Kit for 2 Modules
Step 2: Mounting the DIN Rail to a Surface
The expansion modules, serial adapters and serial converters
weigh approximately 1.5 oz (42 grams) each so the mounting
hardware does not need to be overly strong. We recommend two
#10 pan head screws as shown in Figure 6, but only because
they best accommodate the slots in the DIN rail. The amount of
strain the wiring might place on the module mounting needs to be
considered also. In many cases, DIN rail with double-sided tape
might be acceptable, although not recommended in areas of high
vibration or extreme hot or cold temperatures.

Step 3: Mounting Modules to the DIN Rail
To mount modules to DIN rail, first locate the approximate desired
position to place the module on the DIN rail, then hook the hinge
end of the mounting clip to the edge of the DIN rail as shown in
Figure 8. Next lower the opposite “latch end” of the clip onto the
rail. Press down on the module until the latch end snaps in place.
A typical installation will look like Figure 9 once modules are
mounted to the DIN rail.
When choosing a location to mount the DIN rail, keep in mind that
wires will be entering both ends of the modules as shown in
Figure 7. Leave enough room on either end of module to allow
for wire routing to prevent undue stress placed on the module’s
connectors and mounting clips. The DIN rail may be mounted on
any vertical or horizontal mounting surface.
Step 4: Connections
After mounting the device(s), refer to the Instruction Manual for
each module for proper connections and operation.
