Function

Redundant ControlNet communication: Equipped with two ControlNet ports (Comm A and Comm B), it supports redundant network topology. When one port or network fails, data is automatically switched to the other port to ensure high availability.

Supports ControlNet 1.5 version and is more suitable for high-reliability applications compared to 1794-ACN15 (single-port, non-redundant).

Modular I/O support: Up to 8 Flex I/O modules can be connected, supporting up to 256 digital I/O points, and adapting to various I/O combinations.

Status indication: Equipped with LED indicator lights, including module status, I/O status, ControlNet port A and B status, for real-time monitoring and fault diagnosis.

Efficient configuration: Configured through the ControlLogix system and RSNetWorx software, it supports rapid setup and debugging, shortening the system launch time.

Installation flexibility: Supports DIN rail or panel installation, and the open design facilitates maintenance and expansion.

Application scenarios

Distributed I/O system: Widely used in factory automation, such as manufacturing, automotive production lines and packaging equipment, it enables remote I/O control through the ControlNet network.

High availability applications: Redundant ControlNet ports make it suitable for mission-critical scenarios such as the oil and gas, power, and water treatment industries, ensuring continuous system operation in the event of network failures.

Process control: It is used in the chemical, pharmaceutical and food and beverage industries that require precise data acquisition and control, and supports complex distributed control systems.

Industrial automation: In conjunction with Flex I/O modules, it is suitable for controlling sensors, actuators, valves and other equipment, and is widely used in conveyor belts, pump systems and HVAC applications.

High-reliability environment: Suitable for scenarios that require high reliability and rapid response, such as aerospace and heavy machinery manufacturing.
