Function

High-precision temperature measurement

Designed specifically for thermocouples and millivolt inputs, it is suitable for high-precision temperature measurement.

Supports multiple types of thermocouples (B, C, E, J, K, N, R, S, T), suitable for different temperature ranges and application requirements.

It provides 24-bit high resolution to ensure the accuracy and stability of data collection.

Non-isolated high-density design

The high-density configuration of 16 channels is suitable for complex systems that require multi-point temperature monitoring.

Non-isolated design is suitable for environments where the signal has a common ground.

Data processing and format:

Supports integer mode (left-aligned, 2's complement) and IEEE 32-bit floating-point format, flexibly adapting to the requirements of different control systems.

Built-in timestamp function, supporting Event Sequence (SOE) applications, facilitating precise recording of data time points.

Diagnostic and protective functions:

Overvoltage/undervoltage detection: An alarm is triggered when the input signal exceeds the range.

Disconnection detection: A warning is issued when a channel disconnection or terminal block removal is detected.

CJC support: Cold end compensation is carried out through external CJC sensors to enhance the accuracy of temperature measurement.

Network compatibility

It can communicate with the ControlLogix controller via ControlNet or EtherNet/IP network, and is suitable for distributed control systems.

Support hot-swappable modules and terminal block removal to enhance maintenance convenience.

Status display: Equipped with LED status indicator lights for convenient on-site monitoring of the module's operating status.

Application scenarios

Industrial Automation

Petroleum and natural gas: It is used to monitor the temperature of pipelines, storage tanks and processing equipment to ensure the safety and stability of the technological process.

Electricity generation: It is used for temperature monitoring of key equipment such as boilers and turbines in power plants to optimize operational efficiency and prevent overheating.

Food and beverage processing: Monitor and control temperature during the food processing to ensure product quality and compliance with hygiene standards.

Complex control system

It is suitable for advanced control applications that require high-precision and multi-channel temperature measurement, such as chemical reactors, heat treatment furnaces or environmental test chambers.

In a distributed control system, it is integrated with the main controller through ControlNet or EtherNet/IP networks for centralized monitoring in large factories.

Environmental monitoring: It is used in environmental control systems, such as HVAC (Heating, Ventilation and Air Conditioning) or cold storage, to monitor and regulate temperature to maintain specific environmental conditions.

Scientific research and testing: In laboratories or testing environments, it is used for high-precision temperature data collection. Combined with millivolt input function, it supports multiple sensor types.

Process control: In scenarios where real-time temperature data and event sequence recording are required, it is used to optimize process flows and diagnose faults, such as in the metallurgical or pharmaceutical industries.
