Others: Supports live plug and unplug (RIUP), with no isolation between channels

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, suitable for multi-node network environments, and has no limit on the number of installation instances (following the requirements of the Flex I/O system).

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

The design is adapted to industrial environments, featuring seismic and vibration resistance capabilities as well as a wide operating temperature range.

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.

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.

High-density application: The 16-channel design is suitable for control cabinets with limited space, providing an efficient output solution.
