About the Allen-Bradley 1734-AENTR

The 1734-AENTR is a POINT I/O 2-port EtherNet I/O adapter module. It supplies field power of 10 to 28.8V DC at 9 A and up to 5V DC at 0.8 A on the POINTBus. It works from -20 °C to +55 °C and mounts on DIN rail in an open-style housing with no enclosure type rating. Isolation is 50V continuous with reinforced insulation between all circuits.

What is the 1734-AENTR used for?

It is the head of a POINT I/O node: it connects the I/O modules beside it to the controller over EtherNet/IP and feeds them power.

Lifecycle and successor
