Allen Bradley 1794-AENTR Ethernet Adapter | FLEX I/O With Good Price In Stock

The Allen-Bradley 1794-AENTR is a Flex I/O communication adapter. This adapter is a DIN rail mounted device, which features Two (2) Ethernet communication port, used for connection Flex I/O rack to a central, ethernet enabled controller. It supports 10/100 Mbps communication rate with an input voltage requirement of 19.2 - 31.2 VDC. It supports installation of up to Eight (8) Flex I/O modules.

The Allen-Bradley module 1794-AENTR is a component module of the Flex I/O product family. This module is a redundant Ethernet communication adapter, typically used to implement high-availability Ethernet network as it supports implementation of Device Level Ring (DLR) topology.

Ethernet connectivity is achieved via the Dual RJ45 ports that supports Ethernet I/P protocol. These ports support Linear for simple communication network and Ring topology for High availability network. It supports 10/100 Mbps communication rate and capable of interfacing up to Eight (8) Flex I/O modules to the controller connected in the network.

The 1794-AENTR is directly mounted to a DIN rail. Inspect installation point for excessive vibration and shock. Operating vibration and shock acceptable for the module is 5g and 30g respectively. An external power supply with nominal supply voltage of 24VDC must be connected to the power terminals of the 1794-AENTR to energize the module. Acceptable voltage supply range is 19.2…31.2V DC, including 5% AC ripple. Conductor wire size recommended when establishing connections to the module is 0.33...3.31 sq. mm or 22...12 AWG, stranded copper wire with insulation rating of 75 °C or 167 °F or higher and maximum insulation thickness of 1.2 mm or 3/64 in.

This module is provided with status indicators that may help users in troubleshooting and monitoring the module. It has bi-color LED indicators that provide status regarding Module, Network, Ethernet Link1 and Ethernet Link2. Module and Network status LED are lit Green when normal and Red when experiencing problems. Link 1 and Link 2 status lit flashing yellow for 10 Mbps connections and green for 100 Mbps connection.

The Allen-Bradley 1794-AENTR is a Flex I/O dual-port EtherNet/IP redundant media adapter module. It can handle up to 8 I/O modules and it has a communication rate of 10 to 100 Mbps. It comes with an inrush current of 18 Amps for 2 milliseconds. It has a nominal input voltage of 24 Volts DC and an input voltage range of 19.2 to 31.2 Volts DC, which includes the 5% AC ripple. This module has a maximum power consumption of 500 mA and one of 400 mA at 24 Volts DC and a maximum Flexbus output of 640 mA at 5 Volts DC.

Ethernet adapter modules like the 1794-AENTR connect Ethernet/IP-enabled controllers like the ControlLogix and CompactLogix. It comes with status indicators that allow the users to monitor the conditions of the network (red/green), the module (red/green), and both links (yellow/green). The isolation voltage of this module is continuous at 50 Volts and it has a basic isolation type. It has been type-tested from power to Flexbus and to Ethernet at 1000 Volts AC for 60 seconds. It has a maximum power dissipation of 7.1 W at 19.2 Volts DC and a thermal dissipation of 24.2 BTU/hour at 24 Volts DC.

Installing and removing this module should not be done when it is powered on. The power source of this module should be Safety Extra Low Voltage (SELV)-compliant or Protected Extra Low Voltage (PELV)-compliant to comply with the CE Low Voltage Directive (LVD). Mounting is done with a DIN rail. No network scheduling and no routing tables are required for this module. The 1794-AENTR module can communicate with FLEX I/O modules on the same DIN rail. Note that users need to configure the IP address and the optional gateway address and subnet mask before using this module. The entire 1794-AENTR module measures 3.4 x 3.7 x 2.7 inches. This adapter is suitable for certain application requirements that use an Ethernet network. These include when there is a need for data to be sent regularly or for plant management. There is a built-in switch for high levels of availability and for drive configuration, data collection, and process control on a single, high-speed network, with internet/intranet connections. It uses the Control and Information Protocol (CIP).
