Function

High-precision temperature measurement

Supports multiple RTD sensors (platinum, nickel, copper) and direct resistance input, suitable for high-precision temperature or resistance measurement.

16-bit resolution (7.7-60 mΩ/bit, depending on the range), providing high-precision data acquisition.

It supports 3-wire and 4-wire RTD wiring. The 4-wire system can compensate for the resistance of the wire and improve the measurement accuracy.

Channel isolation

Each channel is independently isolated (channel-to-channel, channel-to-backplane), providing a 250V isolation voltage to reduce ground loops and electromagnetic noise interference and ensure signal integrity.

Flexible data processing

Support two data formats:

Integer mode: Offers multi-range selection, notch filtering and real-time sampling.

Floating-point mode: It includes integer mode functionality and adds temperature linearization, process alarm, rate alarm and digital filtering.

Support the selection of temperature units (Celsius or Fahrenheit), and the resistance value can be linearized into a temperature value through an RTD meter.

Diagnostic function:

Supports open-circuit detection (negative full-scale reading is reported within 5 seconds; if only end A is open-circuited, it is positive full-scale).

It provides process alarm, rate alarm, over-range/under-range detection and module health status monitoring.

The 10 Ω copper RTD supports offset compensation to reduce small-scale errors.

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.

Software configuration:

Configuration is carried out using Studio 5000 software, which supports independent setting of RTD type, range, filtering and alarm parameters for each channel.

Supports real-time sampling and timestamp functions, suitable for sequential event (SOE) applications.

Application scenarios

Process control

In the petrochemical, oil refining, pharmaceutical or food processing industries, it is used to monitor key temperature parameters such as the temperature of reactors, pipelines or storage tanks.

Channel isolation and high noise suppression capabilities are suitable for complex electromagnetic environments, ensuring measurement accuracy.

Industrial Automation

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

Supports 3-wire and 4-wire RTD to meet the configuration requirements of different sensors.

Data Acquisition System

In laboratories or test platforms, high-precision temperature or resistance data can be collected, which is suitable for scientific research or quality control.

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.

High-reliability scenarios:

The channel isolation and diagnostic functions make it suitable for scenarios with high reliability requirements, such as power systems, aerospace or critical infrastructure.

The 10 Ω copper RTD offset compensation function is suitable for high-precision low-temperature measurement.
