Status indication: LED indicator light (I/O status, communication status A)

Function

ControlNet Communication

Supports the ControlNet protocol, with a communication rate up to 5 Mbps, suitable for real-time data transmission and control.

A single ControlNet port (BNC interface) is provided for non-redundant network architectures (if redundancy is required, 1794-ACNR15 should be used).

Supports Daisy chain or star topology, using Belden RG-6/U coaxial cable.

I/O extension

Up to 8 Flex I/O modules can be connected, supporting any combination of digital, analog or special modules, and flexibly adapting to different application requirements.

Convert the input power supply (24V DC) to the backplane power supply (5V DC, 640 mA) to supply power to the adjacent Flex I/O modules.

Status monitoring

It is equipped with LED status indicator lights to display the I/O status and ControlNet communication status, facilitating quick diagnosis of network or module issues.

Support configuration and monitoring via RSNetWorx for ControlNet or Studio 5000 Logix Designer.

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.

Supports DIN rail or panel installation, suitable for control cabinets with limited space.

Fault Diagnosis:

Provide network diagnostic functions to monitor the network status of ControlNet and the health status of modules.

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

Easy to configure

Online configuration can be carried out through the ControlNet network, simplifying system Settings and debugging.

Application scenarios

Distributed Control System (DCS)

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

It is suitable for scenarios that require high real-time and deterministic communication, such as the automotive manufacturing, petrochemical or 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

It is applied in industries such as chemical engineering, petroleum and natural gas, and water treatment, connecting analog or digital I/O modules to monitor and control process variables (such as temperature, pressure, and flow rate).

Suitable for process automation systems that require high reliability and rapid response.

Application in hazardous Locations: The module has passed the European Zone 2 and North American hazardous location certifications and is suitable for some hazardous environments (such as the petrochemical or pharmaceutical industries).

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