Function

EtherNet/IP communication

Supports dual-port EtherNet/IP, is compatible with Device Level Ring (DLR) topology, and provides network redundancy to improve system availability.

Supports 10/100 Mbps communication rate, half-duplex/full-duplex mode, suitable for real-time data transmission and control.

It is configured through RSLinx and Studio 5000 Logix Designer to support RSNetWorx for EtherNet/IP network diagnosis.

I/O extension

Up to 8 Flex I/O modules can be connected, supporting digital input/output, analog input/output or special modules (such as counters, thermocouple modules), flexibly adapting to various application requirements.

Provide the backplane power supply (5V DC, 640 mA) to power the adjacent Flex I/O modules.

Status monitoring

It is equipped with dual-color LED indicator lights to display the Module status (Module), Network status (Network), and Ethernet connection status (Link 1/Link 2), facilitating rapid diagnosis.

Support network diagnostic function to monitor the health status of EtherNet/IP networks and modules.

Redundant network support

The dual RJ45 ports support DLR topology. When a single point of failure occurs in the network, the path can be automatically switched to ensure communication continuity.

It also supports linear or star topologies, suitable for different network architectures.

Compact design

The module integrates communication adapter and power conversion functions, simplifying the design of distributed I/O systems and reducing wiring and space requirements.

DIN rail mounting, suitable for control cabinets with limited space.

Easy to configure and maintain:

Supports automatic device replacement (ADR), facilitating module replacement and maintenance.

Online configuration and firmware update can be carried out through Studio 5000 Logix Designer or RSLogix 5000 (version 20 or higher).

Application scenarios

Distributed Control System (DCS)

Communicate with Allen-Bradley's Logix controllers (such as ControlLogix, CompactLogix) or other EtherNet/ IP-compatible devices via EtherNet/IP networks, and is suitable for distributed I/O expansion in large factories or production lines.

It is suitable for scenarios that require network redundancy, such as the automotive manufacturing, petrochemical, and food and beverage industries.

Machine control

It is used to monitor and control I/O signals in mechanical equipment, such as driving solenoid valves, relays or monitoring the status of sensors.

It is commonly found in packaging machines, conveying systems, assembly lines and other equipment.

Process control: Applied in industries such as chemical engineering, oil and gas, and water treatment, it connects analog or digital I/O modules to monitor and control process variables (such as temperature, pressure, and flow rate).

The DLR topology ensures high availability and is suitable for critical process control.

Application in hazardous locations: The module has passed ATEX and IECEx certifications and is suitable for some hazardous environments.

Building automation: It is used in building management systems to connect I/O modules to control HVAC, lighting or security systems.
