Function

High-density output

It provides 16 24V DC current source output channels, suitable for driving 24V DC devices such as indicator lights, relay coils, and solenoid valves.

Each channel is equipped with an electronic fuse to provide overload and short-circuit protection, enhancing reliability.

The yellow LED indicator lights show the status of each channel and light up when the signal is output, facilitating quick diagnosis.

Communication and Integration

Integrate with PLCS (such as ControlLogix, CompactLogix, PLC5, SLC 500) through Flex I/O adapters (such as Ethernet, ControlNet, DeviceNet).

Supports distributed I/O architecture, is compatible with multiple industrial network protocols, and has no limit on the number of installation instances (following the requirements of the Flex I/O system).

Adaptability to extreme environments

Designed for extreme environments (-20 to 70°C), it complies with G3 corrosion standards and is suitable for harsh industrial conditions.

Compatible with the ControlLogix-XT extreme environment system, it provides higher reliability.

Flexible installation

Modular design, supporting live plugging and unplugging, simplifies maintenance and replacement.

Compatible with multiple terminal bases, it supports DIN rail or panel installation and offers flexible wiring options.

Durability

It has the ability to resist earthquakes and vibrations and a wide operating temperature range, making it suitable for harsh industrial environments.

Support hazardous location certification (such as Class I Div 2), applicable to specific industrial scenarios.

Application scenarios

Manufacturing industry: Used for production line control, driving indicator lights, relays or solenoid valves, suitable for automotive manufacturing, food processing, packaging equipment.

Process control: In the chemical, oil and gas, and water treatment industries, it controls actuators or alarm devices, which is particularly suitable for extreme temperature or corrosive environments.

Factory automation: Integrated into the distributed control system via Ethernet or ControlNet, it works in coordination with PLC and HMI to achieve automated control.

Data recording: Records the output status for alarm and event logs, suitable for industries such as pharmaceuticals and food and beverage that require compliance recording.

Extreme environment applications: such as offshore platforms, mining, cold or high-temperature environments, benefiting from its XT extreme environment design and G3 corrosion protection.
