Function

Ac input

Supports 8 220V AC input channels, suitable for connecting AC signal devices (such as buttons, proximity sensors, relay contacts).

Each channel is equipped with a yellow LED indicator light that lights up when the signal is present, facilitating status monitoring and fault diagnosis.

Communication and Integration

Integrate with PLCS (such as ControlLogix, CompactLogix, SLC 500) or other controllers 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).

Flexible installation

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

Compatible with multiple terminal bases, it offers flexible wiring and DIN rail mounting 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: It is used for production line monitoring, connecting AC sensors or switches to collect equipment status signals, and is suitable for automotive manufacturing and food processing.

Process control: In the chemical, water treatment, and oil and gas industries, AC input signals (such as level switches and pressure switches) are collected.

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

Data recording: Records switch signals for alarm and event logging, suitable for industries such as pharmaceuticals and food and beverage that require compliance recording.

Ac signal application: Suitable for scenarios requiring high-voltage AC input, providing reliable signal acquisition.
