Function

High-precision analog input

Supports 8 single-ended analog input channels, capable of receiving 0-20mA, 4-20mA, ±10V DC, and 0-10V DC signals, suitable for connecting various analog devices (such as transmitters and sensors).

12-bit resolution (unipolar) or 11-bit signed (bipolar), providing high-precision signal conversion.

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 and is compatible with multiple industrial network protocols.

Flexible installation

Modular design, compatible with various terminal bases, supports DIN rail or panel installation.

Supports live plugging and unplugging, simplifying maintenance and replacement.

Diagnosis and Configuration

It can be configured through FactoryTalk or PLC programming software (such as RSLogix 5000), and supports independent setting of channels (current/voltage).

Provide real-time signal status feedback and return 0V/ 0mA when the channel is closed.

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 analog sensors (such as pressure, temperature, and flow sensors) to collect process data, and is suitable for automotive manufacturing and food processing.

Process control: In the chemical, oil and gas, and water treatment industries, signals from transmitters (such as 4-20 mA) are collected, and parameters such as liquid level and flow rate are monitored.

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 analog signal data for alarm and event logging, suitable for industries such as pharmaceuticals and food and beverage that require compliance recording.

High-density applications: The 8-channel design is suitable for control cabinets with limited space, providing an efficient analog input solution.
