Function

High-density analog input

It supports 12 single-ended analog input channels and can receive 0-20mA, 4-20mA, ±10V DC, and 0-10V DC signals, making it suitable for connecting analog devices such as transmitters, indicators, and recorders.

16-bit resolution (unipolar) or 15-bit signed (bipolar), providing high-precision signal acquisition.

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 suitable for multi-node network environments.

Flexible configuration

Each channel can be independently configured as voltage or current input and supports over-limit notification.

Configuration is carried out using FactoryTalk or RSLogix 5000 software, and the data is stored in 16-bit left-aligned registers.

Installation and maintenance

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

Compatible with 1794-TB3G and 1794-TB3GS terminal bases, supporting DIN rail or panel mounting.

Durability

Suitable for industrial environments, it features 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 12-channel design is suitable for control cabinets with limited space, providing an efficient analog input solution.
