Allen-Bardley 1794-AENTR FLEX I/O Dual Port EtherNet/IP Communication Adapter Module

The FLEX I/O Dual Port EtherNet/IP Communication Adapter Module (1794-AENTR) includes two EtherNet/IP ports configured as embedded switches that support not only the conventional star and tree topologies but also the daisy chain and Device Level Ring (DLR) topologies. The DLR topology provides a level of communication redundancy that enhances product availability. DLR also reduces and simplifies network wiring.

It can connect up to eight FLEX I/O modules per adapter module. The extreme environment (1794-AENTRXT) version of the communication adapter module operates in a broader temperature spectrum of -20 to 70°C and provides a solution for extreme environment applications.

FLEX I/O is claimed to be a cost-effective, flexible, modular I/O system for distributed applications and offers the functions of larger rack-based I/O, without the space requirement. Users can independently select the I/O type, termination and network.
