The following applies when you physically mount the unit.
- Horizontal mounting is strongly recommended to achieve maximum heat dissipation and meet the operating temperature upper limit. Any other mounting orientation reduces the upper limit.
- Mounting on a 35 mm wide DIN rail is recommended. The controller's unit base has a molded DIN rail slot and locking clip, as do option modules. DIN rail mounting ensures alignment of the connectors between the devices.
- Up to four option modules are supported.
- Dimensions of a unit appear in the
following figure. Figure 1. Mounting dimensions of Controller and option modules
