Function

Wiring support:

It provides 16 I/O terminals, suitable for connecting digital input/output modules, and supports high-density signal wiring.

Two common terminals and two power terminals simplify power distribution and common signal connection.

The NeMA-style screw clamping supports larger wire diameters (up to 12 AWG), ensuring reliable connections.

Communication and Integration

Integrate with PLCS (such as ControlLogix, CompactLogix, SLC 500) through Flex I/O modules and adapters (such as 1794-AENT, 1794-ACN15).

Supports distributed I/O architecture and is compatible with protocols such as Ethernet, ControlNet, and DeviceNet.

Flexible installation

Modular design, supporting DIN rail or panel installation, adaptable to different control cabinet layouts.

Supports live plugging and unplugging, facilitating module replacement and maintenance.

Durability

The design is adapted to industrial environments, featuring seismic and vibration resistance capabilities as well as a wide operating temperature range (-20 to 70°C).

Wiring protection

Provide I/O wiring protection covers to prevent dust and accidental contact, enhancing safety.

Clear terminal numbers and labels facilitate installation and commissioning.

Application scenarios

Manufacturing industry: It is used for production line control, connecting digital output modules (such as 1794-OA8, 1794-OW8), driving relays, solenoid valves or indicator lights, and is suitable for automotive manufacturing and food processing.

Process control: In the chemical, oil and gas, and water treatment industries, it works in conjunction with output modules to control 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 status of output signals for alarm and event logging, suitable for industries such as pharmaceuticals and food and beverage that require compliance recording.

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