Hirschmann BRS20-04009999-TTCY99HHSESXX.X.XX Extended-Temperature Copper Ethernet Selection for Small Industrial Control Cabinets
Hirschmann BRS20-04009999-TTCY99HHSESXX.X.XX is the BRS20-4TX-EEC configuration of the Hirschmann BOBCAT family. A small machine network often needs only a few managed connections, but its enclosure may experience substantial temperature changes. This four-port EEC model combines a compact DIN rail footprint with the extended operating range listed for the exact configuration.

Four copper connections in a compact cabinet
Allocate the four RJ45 connections before ordering: a link to the upstream network occupies one of the same four physical ports. Allow spare capacity if additional controllers, operator panels or service connections are expected later.

Cabinet supply planning
- Catalog supply: 2 x 12 VDC ... 24 VDC; listed power consumption: 5 W.
- For a four-port machine node, include the switch load in the cabinet power schedule before allocating spare terminals. Record which supply circuit feeds each input; connecting both inputs to one unprotected source does not establish an independent backup supply.
Does EEC mean the switch can be mounted outdoors without an enclosure?
No. The extended temperature range and the IP30 enclosure rating describe different properties. Cabinet protection, condensation control and the installation instructions still determine a suitable location.
Controller integration and software
The catalog identifies EtherNet/IP, PROFINET, Modbus TCP and IEC 61850 MMS switch-model profiles. For a small machine network, first establish which integration profile the controller project actually needs, then verify the delivered software and commissioning requirements. The switch is not being specified as a protocol converter.
