Mounting Dimensions DIN Rail Mounting
Mounting dimensions exclude mounting feet or DIN Rail latches.
Figure 3 - DIN Rail Mounting [mm (in.)]
Maintain spacing from objects such as enclosure walls, wireways, and adjacent
equipment. Allow 50.8 mm (2 in.) of space on all sides for adequate ventilation. If
optional accessories/modules are attached to the relay, such as the power supply
Cat. No. 2080-PS120-240VAC, make sure that there is 50.8 mm (2 in.) of space
on all sides after attaching the optional parts.
The module can be mounted using the following DIN Rails:
35 x 7.5 x 1 mm (EN 50 022 - 35 x 7.5).
To mount the module on a DIN Rail:
1. Use a flat-blade screwdriver in the DIN Rail latch and pry it downwards
until it is in the unlatched position.
2. Hook the top of the DIN Rail mounting area of the relay onto the DIN
Rail, and then press the bottom until the relay snaps onto the DIN Rail.
3. Push the DIN Rail latch back into the latched position.
Use DIN Rail end anchors (Allen-Bradley Cat. Nos. 1492-EAJ35 or
1492­EAHJ35) for vibration or shock environments.
To remove the module from the DIN Rail, pry the DIN Rail latch downwards
until it is in the unlatched position.
For environments with greater vibration and shock concerns, use the panel
mounting method, instead of DIN Rail mounting.
