The Allen-Bradley 1794-AENT is a powerful communication adapter for distributed I/O systems. It connects a Flex I/O rack directly to an Ethernet network. This adapter lets you exchange data with Ethernet-enabled controllers efficiently. The module supports a communication rate of 10/100 Mbps. It requires an input voltage range from 19.2 to 31.2 VDC. This device allows installation of up to eight Flex I/O modules.
Product Procurement & Buyer Guide
Industrial engineers and procurement managers choose the 1794-AENT for its reliability. It solves the pain point of implementing remote I/O architectures. This adapter acts as remote I/O for PLC-5 and SLC 500 controllers. It also works seamlessly with CompactLogix and ControlLogix platforms.
The module supports both discrete and analog I/O modules. You can install input and output modules in any combination. This flexibility reduces your total system cost significantly. The adapter uses a single RJ45 port for Ethernet/IP protocol. It supports linear network topologies for simple wiring. This design lowers installation complexity and saves panel space.
You must match the power supply to its specifications. The nominal input voltage rating is 24 Volts DC. The adapter’s maximum power consumption is 550 mA. Operating voltage range includes a 5% AC ripple tolerance. The module’s maximum power dissipation is 7.3 W.
Step-by-Step User & Installation Guide
Mount the 1794-AENT on a standard DIN rail first. Secure the module firmly to the rail. Connect the Ethernet cable to the single RJ45 port. Use a Category 5 cable for best performance.
Power the adapter using a 24 VDC supply. Use stranded copper wire with 22 to 12 AWG size. The wire insulation must be rated for 75 °C. Tighten terminal screws to 0.8 Nm of torque. The module requires 450 mA current at 24 VDC.
Configure the network address using thumbwheel switches. You can also use a DHCP server for automatic setup. The default switch setting is 999. Check the module status indicator for network health. The red/green LED shows module and network status.
