Function

High-density analog input

Supports 16 single-ended, 8 differential or 4 high-speed differential input channels, suitable for applications with high channel density.

Supports voltage (±10V, 0-10V, 0-5V) and current (0-20mA, 4-20mA) signals, and is compatible with both 2-wire and 4-wire transmitters.

16-bit resolution provides high-precision signal acquisition and is suitable for most industrial applications.

Flexible wiring method:

Single-ended connection: Suitable for scenarios with common ground signals, maximizing the number of channels (16 channels), but sensitive to noise.

Differential wiring: Suitable for scenarios without common ground or requiring high noise reduction capability, the number of channels is reduced to 8.

High-speed differential wiring: Suitable for systems that require rapid data updates, the number of channels is reduced to 4, and the scanning time is the shortest (5-122 ms).

Data Processing and Diagnosis

Supports real-time channel sampling and data alarm (including slope, process, over-range/under-range, and disconnection detection).

Supports engineering unit scaling, timestamp (15 bits, millisecond resolution), and multiple data formats (IEEE 32-bit floating-point or 16-bit integer).

Built-in Sigma-Delta analog-to-digital converter to ensure high precision and stability.

Network integration: Communicate with ControlLogix controllers via ControlNet or EtherNet/IP networks, supporting local or distributed I/O architectures.

Supports hot plugging (RIUP), which is convenient for maintenance and replacement.

Calibration: Factory pre-calibration, supporting recalibration by channel or module as a whole to ensure long-term accuracy.

Producer/consumer communication: Supports an efficient data exchange mode. The module can actively generate data without the need for controller polling, thereby enhancing system efficiency.

Application scenarios

Process control

In the petrochemical, pharmaceutical, water treatment or food processing industries, analog signals (4-20 mA or 0-10 V) of pressure, temperature, flow or level transmitters are collected.

High channel density is suitable for multi-point monitoring systems, such as pipeline pressure or tank liquid level monitoring.

Industrial Automation

It is used in automated production lines in manufacturing to monitor the output of sensors, such as motor current, vibration sensors or temperature sensors.

Single-ended wiring is suitable for low-cost applications of common ground signals, while differential wiring is suitable for environments with high noise.

Data Acquisition System

In test and measurement applications, multiple analog signals are collected for use in laboratory or industrial test platforms.

It supports real-time sampling and alarm functions, making it suitable for dynamic testing that requires rapid data updates.

Distributed control system: Through ControlNet or EtherNet/IP networks, it serves as a remote I/O component and is integrated into large-scale factory automation systems, suitable for cross-regional control.

General industrial applications: Suitable for scenarios with limited budgets and low requirements for isolation between channels, such as monitoring systems in small and medium-sized factories.
