Features:
- Provides the expansion-side IM 312-5 interface with a fixed 0.5 m cable.
- Carries bus communication and operating power to supported compact S5 racks.
- Pairs with the IM 300-5 interface used in the central expansion path.
The CA11 suffix denotes the short fixed-cable version of the IM 312-5.
It lets a supported expansion unit operate without a separate internal power supply.
Available cable reach and cumulative rack current must be verified before the connection is restored.

- EU 184U and EU 187U racks can be placed directly above or near the central controller in compact cabinets.
- Centralized S5 layouts use the fixed interface cable where distributed communication is unnecessary.
- Maintenance replacements preserve a powered expansion path without adding a new rack supply.
- The expansion unit connects to a matching IM 300-5 on the central side.
- Bus signals and rack operating power share the documented interface path.
- Up to three supported expansion units may use one IM 300-5 connection arrangement.
- The fixed 0.5 m cable defines the usable reach between the connected S5 racks.
- The combined interface path carries bus signals and operating power to an expansion rack without its own supply.
- Total loading must remain within the upstream 5 A connection limit.
- Each IM 300-5 connection is limited to 5 A for the attached expansion loads.
- Rack power must be isolated before inserting or removing the fixed interface connector.
- Load calculations prevent overheating or voltage drop in the combined bus-and-power path.
