Function

High-density temperature measurement

It supports 12 three-wire RTD input channels and is suitable for temperature monitoring applications with high channel density.

The 24-bit resolution offers extremely high accuracy (7.7-60 mΩ/bit, depending on the measurement range), making it suitable for precise temperature measurement.

Supports multiple RTD sensors (platinum, nickel, copper) and provides a resistance input range of 1-4000 Ω.

Non-isolated design

The channel to the backplane provides 250V isolation, but there is no isolation between channels, which is suitable for scenarios where signal sources share the same ground.

Compared with isolation modules (such as 1756-IRT8I), it has a lower cost and is suitable for environments with lower noise.

Advanced Data Processing

Supports IEEE 32-bit floating-point data format and is compatible with multiple control systems (such as HMI, SCADA).

It provides digital filtering, notch filtering (10 Hz, 50 Hz, 60 Hz, 100 Hz, 250 Hz, 1000 Hz), real-time sampling and automatic range selection.

Supports temperature linearization (Celsius/Fahrenheit), and can convert resistance values into temperature values.

Diagnostic function:

Supports open circuit detection (broken line detection), over-range/under-range detection, process alarm and rate alarm.

The sensor offset function allows for deviation correction and optimization of measurement accuracy.

The status LED indicator module shows the health, communication and input status, facilitating on-site diagnosis.

Network integration

Communicate with the ControlLogix controller via ControlNet or EtherNet/IP network, supporting local or distributed I/O architecture.

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

Software configuration:

Configured using Studio 5000 software, it supports independent setting of RTD type, range, filtering and alarm parameters for each channel.

Support Add-On Profiles (AOP) to simplify configuration and integration.

Application scenarios

Process control

In the petrochemical, pharmaceutical, food processing or water treatment industries, multiple temperature parameters are monitored, such as the temperatures of pipelines, storage tanks or reactors.

High channel density (12 points) is suitable for systems that need to monitor multiple RTD sensors simultaneously.

Industrial Automation

It is used for temperature monitoring in manufacturing industries, such as heat treatment furnaces, injection molding machines or metal processing equipment.

Non-isolated design is suitable for environments where signal sources share the same ground and have low electromagnetic noise.

Data Acquisition System

In the laboratory or test platform, multiple high-precision temperature data channels are collected, which is suitable for quality control or environmental monitoring.

The real-time sampling and alarm functions support dynamic test scenarios.

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 temperature monitoring.

Cost-sensitive scenarios: Compared with isolation modules (such as 1756-IRT8I), 1756-IR12 offers higher channel density and lower cost, making it suitable for applications with limited budgets but requiring multi-point measurements.
