Function

Isolated output: It provides 4 independently isolated analog output channels to ensure that the channels do not interfere with each other. Even if one channel fails, the others can still operate normally.

Flexible output configuration: Supports user-configurable current and voltage output to meet the needs of various devices.

High resolution and accuracy: 15-bit resolution, providing precise analog signal output, suitable for high-precision control applications.

Modular design: Supports hot plugging, allowing installation or removal while the backplane is powered on (it is recommended to disconnect the on-site power supply to avoid electric arcs).

Compatible with multiple terminal bases, simplifying wiring and maintenance.

Diagnosis and status indication: Equipped with a green power/status indicator light to monitor the module's operating status in real time.

Communication compatibility: Integrated with ControlNet, DeviceNet or EtherNet/IP networks via Flex I/O adapters, suitable for distributed control systems.

Environmental adaptability: XT version is provided, suitable for extreme environments, and compatible with ControlLogix-XT systems.

Application scenarios

Industrial automation: Used in manufacturing and material handling systems, it controls equipment such as frequency converters (VFDS), actuators, and valves, and is suitable for conveyor belts, packaging machines, and robots.

Process control: Applicable to the oil and gas, chemical and water treatment industries, it drives analog control equipment such as control valves, flow controllers and pressure transmitters.

Distributed control system: In conjunction with the Flex I/O system, it is used in distributed I/O architectures, such as automotive production lines and food and beverage processing.

High-precision control: It offers high-resolution analog output and is suitable for applications that require precise signal output, such as HVAC systems, laboratory equipment, and industrial furnace control.

Harsh environments: The XT version is suitable for high-temperature, humid or corrosive environments, such as the Marine engineering and mining industries.
