Physical Mounting

The following applies to mounting a IO-R-16 Remote I/O Module:
Horizontal mounting is preferred to facilitate heat dissipation. It is not necessary to remove the cover before
•
mounting.
Mounting on a 35mm wide DIN rail is recommended. The IO-R-16 unit base has a molded DIN rail slot and
•
locking clip, which simplifies mounting with other modules. Mounting on a DIN rail ensures accurate alignment
of connectors between all modules.
If DIN rail mounting is impractical, you can use screws in mounting tabs on the IO-R-16.

Procedure 1 provides step-by-step instructions for mounting the IO-R-16 module on an installed DIN rail.
Procedure 1 To mount on DIN rail.
Pull or pry down the plastic locking clip until it snaps into the open (down) position.
Step 1
Position the IO-R-16 module on the rail, tilting to hook the top DIN rail tab over the upper edge of the DIN
Step 2
rail (Figure 1). Rotate the module flush against the DIN rail and then press the locking clip upward to
release it and secure the module to the rail.
Slide the IO-R-16 module along the DIN rail to its intended location. If connecting to another mounted
Step 3
module, seat the 5-position plug into that module's connector socket.
Carefully install DIN rail end clips to secure the assembly. Make sure that the DIN rail stops do not press
Step 4
against the end connectors on the IO-R-16.
Do not mount hardware on both a DIN Rail and with tab mounts to another surface. This causes
Caution •
physical stress on equipment and prevents good connections between controller and modules.
Do not mount DIN rail stops so that they press against IO-R-16 end connectors. If possible, use
•
low-profile rail stops to eliminate possibility of contact and damage to the connectors.
Repeat this for all items, until all are mounted on the DIN rail(s), firmly connected to each other, and
Step 5
secured with DIN rail end clips.
