About the Allen-Bradley 5094-AENTR

The 5094-AENTR is a FLEX 5000 Ethernet adapter for 8 modules with RJ45 ports. MP power is 18 to 32V DC at 1250 mA, and the backplane is rated 15V DC at 1130 mA. It dissipates up to 5.1 W at 18V DC, measures approximately 92.7 x 94.0 x 96.5 mm and weighs about 400 g. It works from -40 °C to +70 °C (technical data 5094-TD001) in an open-style housing.

What is the 5094-AENTR used for?

It is the head of a FLEX 5000 I/O node of up to 8 modules, connecting them to the controller over Ethernet. Power is isolated from the backplane and the backplane from Ethernet; the Ethernet ports are not isolated from each other.
