24 volt ethernet hub

[a70duster]

Hello all,

I am installing a Controllogix device and using a Red Lion display for the HMI. I figured out how to get the ethernet working between the two. I am looking for a ethernet hub that operates off of 24 volts and haven't found anything on the net.

Any suggestions are welcome.

Or you can try B&B Electronics, they also make a very good industrial ENet hub and switch.

Westermo have a great range of ethernet products which are hardened for the industrial environment. Highly recommended.

B&B Electronics caters to the industry, with 24VDC powered switches, with integrated DIN rail mounts. They have models that are more rubust and will withstand being in a Hoffman enclosure outside.

Add Hirschmann to the list. I have had good results with their products.

I would also suggest using a switch rather than a hub.

I've used 24 vdc industrial grade Phoenix Contact switches in the past and have been satisfied with them.

To all,

What we need is an industrial grade/ruggedized switch with management capabilities, and that can handle trunking VLANs.

Cisco makes the 2955 series switch, which is a 12 port fully manageable, Din rail mounted unit. It is their “industrial” offering. It works well, we have several in operation, but it is bulky, and only runs off 24VDC. Many other industrial switches have the standard 10-30 VDC range on the input power.

Does anyone know of a good managed switch for the industrial arena?

As catserveng, said

They have the best Industrial managed switches available.

remember, always use a switch, hubs cause problems, I believe AB does not recommend using hubs anymore for any reason.

robertjo,

Take a look at Westermo's R200 and U200 switches on my previous link. I believe both have VLAN capability.
